Maintaining a platform for monitoring everything imaginable requires a broad understanding of a plethora of technologies, systems and applications. We rely on community contributions and user feedback to continue providing the best monitoring solution out there. + +There are many ways to contribute, with varying requirements of skills: + +## All NetData Users + +### Give Netdata a GitHub star + +This is the minimum open-source users should contribute back to the projects they use. Github stars help the project gain visibility, stand out. So, if you use Netdata, consider pressing that button. **It really matters**. + +### Spread the word + +Community growth allows the project to attract new talent willing to contribute. This talent is then developing new features and improves the project. These new features and improvements attract more users and so on. It is a loop. So, post about netdata, present it to local meetups you attend, let your online social network or twitter, facebook, reddit, etc. know you are using it. **The more people involved, the faster the project evolves**. + +### Provide feedback + +Is there anything that bothers you about netdata? Did you experience an issue while installing it or using it? Would you like to see it evolve to you need? Let us know. [Open a github issue](https://github.com/netdata/netdata/issues) to discuss it. Feedback is very important for open-source projects. We can't commit we will do everything, but your feedback influences our road-map significantly. **We rely on your feedback to make Netdata better**. + +#### Help the developers understand what they have to do + +NetData is all about simplicity and meaningful presentation. It's impossible for a handful of people to know which metrics really matter when monitoring a particular software or hardware component you are interested in. Be specific about what should be collected, how the information should be presented in the dashboard and which alarms make sense in most situations. + +## Experienced Users + +### Help other users + +As the project grows, an increasing share of our time is spent on supporting this community of users in terms of answering questions, of helping users understand how netdata works and find their way with it. Helping other users is crucial. It allows the developers and maintainers of the project to focus on improving it. + +### Improve documentation + +Most of our documentation is in markdown (.md) files inside the netdata GitHub project. What remains in our Wiki will soon be moved in there as well. Don't be afraid to edit any of these documents and submit a GitHub Pull Request with your corrections/additions. + + +## Developers + +We expect most contributions to be for new data collection plugins. You can read about how external plugins work [here](collectors/plugins.d/). Additional instructions are available for [Node.js plugins](collectors/node.d.plugin) and [Python plugis](collectors/python.d.plugin). + +Of course we appreciate contributions for any other part of the NetData agent, including the [daemon](daemon), [backends for long term archiving](backends/), innovative ways of using the [REST API](web/api) to create cool [Custom Dashboards](web/gui/custom/) or to include NetData charts in other applications, similarly to what can be done with [Confluence](web/gui/confluence/). + + +### Contributions Ground Rules + +#### Code of Conduct and CLA + +We expect all contributors to abide by the [Contributor Covenant Code of Conduct](CODE_OF_CONDUCT.md). For a pull request to be accepted, you will also need to accept the [netdata contributors license agreement](CONTRIBUTORS.md), as part of the PR process. + +#### Performance and efficiency + +Everything on Netdata is about efficiency. We need netdata to always be the most lightweight monitoring solution available. We will reject to merge PRs that are not optimal in resource utilization and efficiency. + +Of course there are cases that such technical excellence is either not reasonable or not feasible. In these cases, we may require the feature or code submitted to be by disabled by default. + +#### Meaningful metrics + +Unlike other monitoring solutions, Netdata requires all metrics collected to have some structure attached to them. So, Netdata metrics have a name, units, belong to a chart that has a title, a family, a context, belong to an application, etc. + +This structure is what makes netdata different. Most other monitoring solution collect bulk metrics in terms of name-value pairs and then expect their users to give meaning to these metrics during visualization. This does not work. It is neither practical nor reasonable to give to someone 2000 metrics and let him/her visualize them in a meaningful way. + +So, netdata requires all metrics to have a meaning at the time they are collected. We will reject to merge PRs that loosely collect just a "bunch of metrics", but we are very keen to help you fix this. + +#### Automated Testing + +Netdata is a very large application to have automated testing end-to-end. But automated testing is required for crucial functions of it. + +Generally, all pull requests should be coupled with automated testing scenarios. However since we do not currently have a framework in place for testing everything little bit of it, we currently require automated tests for parts of Netdata that seem too risky to be changed without automated testing. + +Of course, manual testing is always required. + +#### Netdata is a distributed application + +Netdata is a distributed monitoring application. A few basic features can become quite complicated for such applications. We may reject features that alter or influence the nature of netdata, though we usually discuss the requirements with contributors and help them adapt their code to be better suited for Netdata. + +#### Operating systems supported + +Netdata should be running everywhere, on every production system out there. + +Although we focus on **supported operating systems**, we still want Netdata to run even on non-supported systems. This, of course, may require some more manual work from the users (to prepare their environment, or enable certain flags, etc). + +If your contributions limit the number of operating systems supported we will request from you to improve it. + +#### Documentation + +Your contributions should be bundled with related documentation to help users understand how to use the features you introduce. + +#### Maintenance + +When you contribute code to Netdata, you are automatically accepting that you will be responsible for maintaining that code in the future. So, if users need help, or report bugs, we will invite you to the related github issues to help them or fix the issues or bugs of your contributions. + diff --git a/CONTRIBUTORS.md b/CONTRIBUTORS.md index fde3d0b4f..46ae396f3 100644 --- a/CONTRIBUTORS.md +++ b/CONTRIBUTORS.md @@ -10,7 +10,7 @@ This agreement is part of the legal framework of the open-source ecosystem that adds some red tape, but protects both the contributor and the project.

This article will be using docker on your local workstation. We will be +working with docker in an ad-hoc way, launching containers that run ‘/bin/bash’ +and attaching a TTY to them. I use docker here in a purely academic fashion and +do not condone running Netdata in a container. I pick this method so individuals +without cloud accounts or access to VMs can try this out and for it’s speed of +deployment. + +## Why Netdata, Prometheus, and Grafana +Some time ago I was introduced to Netdata by a coworker. We were attempting to +troubleshoot python code which seemed to be bottlenecked. I was instantly +impressed by the amount of metrics Netdata exposes to you. I quickly added +Netdata to my set of go-to tools when troubleshooting systems performance. + +Some time ago, even later, I was introduced to Prometheus. Prometheus is a +monitoring application which flips the normal architecture around and polls +rest endpoints for its metrics. This architectural change greatly simplifies +and decreases the time necessary to begin monitoring your applications. +Compared to current monitoring solutions the time spent on designing the +infrastructure is greatly reduced. Running a single Prometheus server per +application becomes feasible with the help of Grafana. + +Grafana has been the go to graphing tool for… some time now. It’s awesome, +anyone that has used it knows it’s awesome. We can point Grafana at Prometheus +and use Prometheus as a data source. This allows a pretty simple overall +monitoring architecture: Install Netdata on your application servers, point +Prometheus at Netdata, and then point Grafana at Prometheus. + +I’m omitting an important ingredient in this stack in order to keep this tutorial +simple and that is service discovery. My personal preference is to use Consul. +Prometheus can plug into consul and automatically begin to scrape new hosts that +register a Netdata client with Consul. + +At the end of this tutorial you will understand how each technology fits +together to create a modern monitoring stack. This stack will offer you +visibility into your application and systems performance. + +## Getting Started - Netdata +To begin let’s create our container which we will install Netdata on. We need +to run a container, forward the necessary port that netdata listens on, and +attach a tty so we can interact with the bash shell on the container. But +before we do this we want name resolution between the two containers to work. +In order to accomplish this we will create a user-defined network and attach +both containers to this network. The first command we should run is: + +``` +docker network create --driver bridge netdata-tutorial +``` + +With this user-defined network created we can now launch our container we will +install Netdata on and point it to this network. + +``` +docker run -it --name netdata --hostname netdata --network=netdata-tutorial -p 19999:19999 centos:latest '/bin/bash' +``` + +This command creates an interactive tty session (-it), gives the container both +a name in relation to the docker daemon and a hostname (this is so you know what +container is which when working in the shells and docker maps hostname +resolution to this container), forwards the local port 19999 to the container’s +port 19999 (-p 19999:19999), sets the command to run (/bin/bash) and then +chooses the base container images (centos:latest). After running this you should +be sitting inside the shell of the container. + +After we have entered the shell we can install Netdata. This process could not +be easier. If you take a look at [this link](../installer/#installation), the Netdata devs give us +several one-liners to install netdata. I have not had any issues with these one +liners and their bootstrapping scripts so far (If you guys run into anything do +share). Run the following command in your container. + +``` +bash <(curl -Ss https://my-netdata.io/kickstart.sh) --dont-wait +``` + +After the install completes you should be able to hit the Netdata dashboard at +http://localhost:19999/ (replace localhost if you’re doing this on a VM or have +the docker container hosted on a machine not on your local system). If this is +your first time using Netdata I suggest you take a look around. The amount of +time I’ve spent digging through /proc and calculating my own metrics has been +greatly reduced by this tool. Take it all in. + +Next I want to draw your attention to a particular endpoint. Navigate to +http://localhost:19999/api/v1/allmetrics?format=prometheus&help=yes In your +browser. This is the endpoint which publishes all the metrics in a format which +Prometheus understands. Let’s take a look at one of these metrics. +`netdata_system_cpu_percentage_average{chart="system.cpu",family="cpu",dimension="system"} +0.0831255 1501271696000` This metric is representing several things which I will +go in more details in the section on prometheus. For now understand that this +metric: `netdata_system_cpu_percentage_average` has several labels: [chart, +family, dimension]. This corresponds with the first cpu chart you see on the +Netdata dashboard. + + + +This CHART is called ‘system.cpu’, The FAMILY is cpu, and the DIMENSION we are +observing is “system”. You can begin to draw links between the charts in netdata +to the prometheus metrics format in this manner. + +## Prometheus +We will be installing prometheus in a container for purpose of demonstration. +While prometheus does have an official container I would like to walk through +the install process and setup on a fresh container. This will allow anyone +reading to migrate this tutorial to a VM or Server of any sort. + +Let’s start another container in the same fashion as we did the Netdata +container. `docker run -it --name prometheus --hostname prometheus +--network=netdata-tutorial -p 9090:9090 centos:latest '/bin/bash'` This should +drop you into a shell once again. Once there quickly install your favorite +editor as we will be editing files later in this tutorial. `yum install vim -y` + +Prometheus provides a tarball of their latest stable versions here: +https://prometheus.io/download/. Let’s download the latest version and install +into your container. + +``` +curl -L 'https://github.com/prometheus/prometheus/releases/download/v1.7.1/prometheus-1.7.1.linux-amd64.tar.gz' -o /tmp/prometheus.tar.gz + +mkdir /opt/prometheus + +tar -xf /tmp/prometheus.tar.gz -C /opt/prometheus/ --strip-components 1 +``` + +This should get prometheus installed into the container. Let’s test that we can run +prometheus and connect to it’s web interface. This will look similar to what +follows: + +``` +[root@prometheus prometheus]# /opt/prometheus/prometheus +INFO[0000] Starting prometheus (version=1.7.1, branch=master, revision=3afb3fffa3a29c3de865e1172fb740442e9d0133) + source="main.go:88" +INFO[0000] Build context (go=go1.8.3, user=root@0aa1b7fc430d, date=20170612-11:44:05) source="main.go:89" +INFO[0000] Host details (Linux 4.9.36-moby #1 SMP Wed Jul 12 15:29:07 UTC 2017 x86_64 prometheus (none)) source="main.go:90" +INFO[0000] Loading configuration file prometheus.yml source="main.go:252" +INFO[0000] Loading series map and head chunks... source="storage.go:428" +INFO[0000] 0 series loaded. source="storage.go:439" +INFO[0000] Starting target manager... source="targetmanager.go:63" +INFO[0000] Listening on :9090 source="web.go:259" +``` + +Now attempt to go to http://localhost:9090/. You should be presented with the +prometheus homepage. This is a good point to talk about Prometheus’s data model +which can be viewed here: https://prometheus.io/docs/concepts/data_model/ As +explained we have two key elements in Prometheus metrics. We have the ‘metric’ +and its ‘labels’. Labels allow for granularity between metrics. Let’s use our +previous example to further explain. + +``` +netdata_system_cpu_percentage_average{chart="system.cpu",family="cpu",dimension="system"} 0.0831255 1501271696000 +``` + +Here our metric is +‘netdata_system_cpu_percentage_average’ and our labels are ‘chart’, ‘family’, +and ‘dimension. The last two values constitute the actual metric value for the +metric type (gauge, counter, etc…). We can begin graphing system metrics with +this information, but first we need to hook up Prometheus to poll Netdata stats. + +Let’s move our attention to Prometheus’s configuration. Prometheus gets it +config from the file located (in our example) at +`/opt/prometheus/prometheus.yml`. I won’t spend an extensive amount of time +going over the configuration values documented here: +https://prometheus.io/docs/operating/configuration/. We will be adding a new +“job” under the “scrape_configs”. Let’s make the “scrape_configs” section look +like this (we can use the dns name Netdata due to the custom user-defined +network we created in docker beforehand). + +```yml +scrape_configs: + # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config. + - job_name: 'prometheus' + + # metrics_path defaults to '/metrics' + # scheme defaults to 'http'. + + static_configs: + - targets: ['localhost:9090'] + + - job_name: 'netdata' + + metrics_path: /api/v1/allmetrics + params: + format: [ prometheus ] + + static_configs: + - targets: ['netdata:19999'] +``` + +Let’s start prometheus once again by running `/opt/prometheus/prometheus`. If we +now navigate to prometheus at ‘http://localhost:9090/targets’ we should see our +target being successfully scraped. If we now go back to the Prometheus’s +homepage and begin to type ‘netdata_’ Prometheus should auto complete metrics +it is now scraping. + + + +Let’s now start exploring how we can graph some metrics. Back in our NetData +container lets get the CPU spinning with a pointless busy loop. On the shell do +the following: + +``` +[root@netdata /]# while true; do echo "HOT HOT HOT CPU"; done +``` + +Our NetData cpu graph should be showing some activity. Let’s represent this in +Prometheus. In order to do this let’s keep our metrics page open for reference: +http://localhost:19999/api/v1/allmetrics?format=prometheus&help=yes We are +setting out to graph the data in the CPU chart so let’s search for “system.cpu” +in the metrics page above. We come across a section of metrics with the first +comments `# COMMENT homogeneus chart "system.cpu", context "system.cpu", family +"cpu", units "percentage"` Followed by the metrics. This is a good start now let +us drill down to the specific metric we would like to graph. + +``` +# COMMENT +netdata_system_cpu_percentage_average: dimension "system", value is percentage, gauge, dt 1501275951 to 1501275951 inclusive +netdata_system_cpu_percentage_average{chart="system.cpu",family="cpu",dimension="system"} 0.0000000 1501275951000 +``` + +Here we learn that the metric name we care about is +‘netdata_system_cpu_percentage_average’ so throw this into Prometheus and see +what we get. We should see something similar to this (I shut off my busy loop) + + + +This is a good step toward what we want. Also make note that Prometheus will tag +on an ‘instance’ label for us which corresponds to our statically defined job in +the configuration file. This allows us to tailor our queries to specific +instances. Now we need to isolate the dimension we want in our query. To do this +let us refine the query slightly. Let’s query the dimension also. Place this +into our query text box. +`netdata_system_cpu_percentage_average{dimension="system"}` We now wind up with +the following graph. + + + +Awesome, this is exactly what we wanted. If you haven’t caught on yet we can +emulate entire charts from NetData by using the `chart` dimension. If you’d like +you can combine the ‘chart’ and ‘instance’ dimension to create per-instance +charts. Let’s give this a try: +`netdata_system_cpu_percentage_average{chart="system.cpu", instance="netdata:19999"}` + +This is the basics of using Prometheus to query NetData. I’d advise everyone at +this point to read [this page](../backends/prometheus/#using-netdata-with-prometheus). +The key point here is that NetData can export metrics from its internal DB or +can send metrics “as-collected” by specifying the ‘source=as-collected’ url +parameter like so. +http://localhost:19999/api/v1/allmetrics?format=prometheus&help=yes&types=yes&source=as-collected +If you choose to use this method you will need to use Prometheus's set of +functions here: https://prometheus.io/docs/querying/functions/ to obtain useful +metrics as you are now dealing with raw counters from the system. For example +you will have to use the `irate()` function over a counter to get that metric’s +rate per second. If your graphing needs are met by using the metrics returned by +NetData’s internal database (not specifying any source= url parameter) then use +that. If you find limitations then consider re-writing your queries using the +raw data and using Prometheus functions to get the desired chart. + +## Grafana +Finally we make it to grafana. This is the easiest part in my opinion. This time +we will actually run the official grafana docker container as all configuration +we need to do is done via the GUI. Let’s run the following command: + +``` +docker run -i -p 3000:3000 --network=netdata-tutorial grafana/grafana +``` + +This will get grafana running at ‘http://localhost:3000/’ Let’s go there and +login using the credentials Admin:Admin. + +The first thing we want to do is click ‘Add data source’. Let’s make it look +like the following screenshot + + + +With this completed let’s graph! Create a new Dashboard by clicking on the top +left Grafana Icon and create a new graph in that dashboard. Fill in the query +like we did above and save. + + + +## Conclusion + +There you have it, a complete systems monitoring stack which is very easy to +deploy. From here I would begin to understand how Prometheus and a service +discovery mechanism such as Consul can play together nicely. My current prod +deployments automatically register Netdata services into Consul and Prometheus +automatically begins to scrape them. Once achieved you do not have to think +about the monitoring system until Prometheus cannot keep up with your scale. +Once this happens there are options presented in the Prometheus documentation +for solving this. Hope this was helpful, happy monitoring. diff --git a/backends/prometheus/README.md b/backends/prometheus/README.md index 826cf051b..99a11f942 100644 --- a/backends/prometheus/README.md +++ b/backends/prometheus/README.md @@ -1,18 +1,21 @@ -> IMPORTANT: the format netdata sends metrics to prometheus has changed since netdata v1.7.

In all places, in the code, there are both the `names` and their `default values`, so if something is not found in the configuration file, the default is used. The lookup is made using B-Trees and hashes (no string comparisons), so they are super fast. Also the `names` of the settings can be `my super duper setting that once set to yes, will turn the world upside down = no` - so goodbye to most of the documentation involved. + +Next, netdata can generate a valid configuration for the user to edit. No need to remember anything. Just get the configuration from the server (`/netdata.conf` on your netdata server), edit it and save it. + +Last, what about options you believe you have set, but you misspelled? When you get the configuration file from the server, there will be a comment above all `name = value` pairs the server does not use.

It has many [internal plugins](../collectors) for collecting most of the metrics presented by default when it starts, collecting data from `/proc`, `/sys` and other Linux kernel sources. + +To collect non-system metrics, netdata supports a plugin architecture. The following are the currently available external plugins: + +- **[Web Servers](#web-servers)**, such as apache, nginx, nginx_plus, tomcat, litespeed +- **[Web Logs](#web-log-parsers)**, such as apache, nginx, lighttpd, gunicorn, squid access logs, apache cache.log +- **[Load Balancers](#load-balancers)**, like haproxy +- **[Message Brokers](#message-brokers)**, like rabbitmq, beanstalkd +- **[Database Servers](#database-servers)**, such as mysql, mariadb, postgres, couchdb, mongodb, rethinkdb +- **[Social Sharing Servers](#social-sharing-servers)**, like retroshare +- **[Proxy Servers](#proxy-servers)**, like squid +- **[HTTP accelerators](#http-accelerators)**, like varnish cache +- **[Search engines](#search-engines)**, like elasticsearch +- **[Name Servers](#name-servers)** (DNS), like bind, nsd, powerdns, dnsdist +- **[DHCP Servers](#dhcp-servers)**, like ISC DHCP +- **[UPS](#ups)**, such as APC UPS, NUT +- **[RAID](#raid)**, such as linux software raid (mdadm), MegaRAID +- **[Mail Servers](#mail-servers)**, like postfix, exim, dovecot +- **[File Servers](#file-servers)**, like samba, NFS, ftp, sftp, WebDAV +- **[System](#system)**, for processes and other system metrics +- **[Sensors](#sensors)**, like temperature, fans speed, voltage, humidity, HDD/SSD S.M.A.R.T attributes +- **[Network](#network)**, such as SNMP devices, `fping`, access points, dns_query_time +- **[Time Servers](#time-servers)**, like chrony +- **[Security](#security)**, like FreeRADIUS, OpenVPN, Fail2ban +- **[Telephony Servers](#telephony-servers)**, like openSIPS +- **[Go applications](#go-applications)** +- **[Household appliances](#household-appliances)**, like SMA WebBox (solar power), Fronius Symo solar power, Stiebel Eltron heating +- **[Java Processes](#java-processes)**, via JMX or Spring Boot Actuator +- **[Provisioning Systems](#provisioning-systems)**, like Puppet +- **[Game Servers](#game-servers)**, like SpigotMC +- **[Distributed Computing Clients](#distributed-computing-clients)**, like BOINC +- **[Skeleton Plugins](#skeleton-plugins)**, for writing your own data collectors + +Check also [Third Party Plugins](Third-Party-Plugins.md) for a list of plugins distributed by third parties. + +## configuring plugins + +netdata comes with **internal** and **external** plugins: + +1. The **internal** ones are written in `C` and run as threads within the netdata daemon. +2. The **external** ones can be written in any computer language. The netdata daemon spawns these as processes (shown with `ps fax`) and reads their metrics using pipes (so the `stdout` of external plugins is connected to netdata for metrics collection and the `stderr` of external plugins is connected to `/var/log/netdata/error.log`). + +To make it easier to develop plugins, and minimize the number of threads and processes running, netdata supports **plugin orchestrators**, each of them supporting one or more data collection **modules**. Currently we ship plugin orchestrators for 4 languages: `C`, `python`, `node.js` and `bash` and 2 more are under development (`go` and `java`). + +#### enabling and disabling plugins + +To control which plugins netdata run, edit `netdata.conf` and check the `[plugins]` section. It looks like this: + +``` +[plugins] + # enable running new plugins = yes + # check for new plugins every = 60 + # proc = yes + # diskspace = yes + # cgroups = yes + # tc = yes + # nfacct = yes + # idlejitter = yes + # freeipmi = yes + # node.d = yes + # python.d = yes + # fping = yes + # charts.d = yes + # apps = yes +``` + +The default for all plugins is the option `enable running new plugins`. So, setting this to `no` will disable all the plugins, except the ones specifically enabled. + +#### enabling and disabling modules + +Each of the **plugins** may support one or more data collection **modules**. To control which of its modules run, you have to consult the configuration of the **plugin** (see table below). + +#### modules configuration + +Most **modules** come with **auto-detection**, configured to work out-of-the-box on popular operating systems with the default settings. + +However, there are cases that auto-detection fails. Usually the reason is that the applications to be monitored do not allow netdata to connect. In most of the cases, allowing the user `netdata` from `localhost` to connect and collect metrics, will automatically enable data collection for the application in question (it will require a netdata restart). + +You can verify netdata **external plugins and their modules** are able to collect metrics, following this procedure: + +```sh +# become user netdata +sudo su -s /bin/bash netdata + +# execute the plugin in debug mode, for a specific module. +# example for the python plugin, mysql module: +/usr/libexec/netdata/plugins.d/python.d.plugin 1 debug trace mysql +``` + +Similarly, you can use `charts.d.plugin` for BASH plugins and `node.d.plugin` for node.js plugins. +Other plugins (like `apps.plugin`, `freeipmi.plugin`, `fping.plugin`) use the native netdata plugin API and can be run directly. + +If you need to configure a netdata plugin or module, all user supplied configuration is kept at `/etc/netdata` while the stock versions of all files is at `/usr/lib/netdata/conf.d`. +To copy a stock file and edit it, run `/etc/netdata/edit-config`. Running this command without an argument, will list the available stock files. + +Each file should provide plenty of examples and documentation about each module and plugin. + +This is a map of the all supported configuration options: + +#### map of configuration files + +plugin | language | plugin<br/>configuration | modules<br/>configuration | +---:|:---:|:---:|:---| +`apps.plugin`<br/>(external plugin for monitoring the process tree on Linux and FreeBSD)|`C`|`netdata.conf` section `[plugin:apps]`|Custom configuration for the processes to be monitored at `apps_groups.conf` +`freebsd.plugin`<br/>(internal plugin for monitoring FreeBSD system resources)|`C`|`netdata.conf` section `[plugin:freebsd]`|one section for each module `[plugin:freebsd:MODULE]`.

To set the data collection frequency, edit `/etc/netdata/netdata.conf` and set `update_every` to a higher number (this is the frequency in seconds data are collected for all charts: higher number of seconds = lower frequency, the default is 1 for per second data collection). You can also set this frequency per module or chart. Check the **[[Configuration]]** section. + +## Plugins + +If a plugin is using a lot of CPU, you should lower its update frequency, or if you wrote it, re-factor it to be more CPU efficient. Check **[[External Plugins]]** for more details on writing plugins. + +## CPU consumption when web clients are accessing dashboards + +Netdata is very efficient when servicing web clients. On most server platforms, netdata should be able to serve **1800 web client requests per second per core** for auto-refreshing charts. + +Normally, each user connected will request less than 10 chart refreshes per second (the page may have hundreds of charts, but only the visible are refreshed). So you can expect 180 users per CPU core accessing dashboards before having any delays. + +Netdata runs with the lowest possible process priority, so even if 1000 users are accessing dashboards, it should not influence your applications. CPU utilization will reach 100%, but your applications should get all the CPU they need. + +To lower the CPU utilization of netdata when clients are accessing the dashboard, set `web compression level = 1`, or disable web compression completely by setting `enable web responses gzip compression = no`. Both settings are in the `[web]` section. + + +## Monitoring a heavy loaded system + +Netdata, while running, does not depend on disk I/O (apart its log files and `access.log` is written with buffering enabled and can be disabled). Some plugins that need disk may stop and show gaps during heavy system load, but the netdata daemon itself should be able to work and collect values from `/proc` and `/sys` and serve web clients accessing it. + +Keep in mind that netdata saves its database when it exits and loads it back when restarted. While it is running though, its DB is only stored in RAM and no I/O takes place for it. + + +## Running netdata in embedded devices + +Embedded devices usually have very limited CPU resources available, and in most cases, just a single core. + +We suggest to do the following: + +#### external plugins + + `charts.d.plugin` and `apps.plugin`, each consumes twice the CPU resources of the netdata daemon. + + If you don't need them, disable them (edit `/etc/netdata/netdata.conf` and search for the plugins section). + + If you need them, increase their `update every` value (again in `/etc/netdata/netdata.conf`), so that they do not run that frequently. + +#### internal plugins + +If netdata is still using a lot of CPU, lower its update frequency. Going from per second updates, to once every 2 seconds updates, will cut the CPU resources of all netdata programs **in half**, and you will still have very frequent updates. + +If the CPU of the embedded device is too weak, try setting even lower update frequency. Experiment with `update every = 5` or `update every = 10` (higher number = lower frequency), until you get acceptable results. + +#### Single threaded web server + +Normally, netdata spawns a thread for each web client. This allows netdata to utilize all the available cores for servicing chart refreshes. You can however disable this feature and serve all charts one after another, using a single thread / core. This will might lower the CPU pressure on the embedded device.

Well, this is a linux box. Why do we need to configure every single metric we need to monitor. Of course it has a CPU and RAM and a few disks, and ethernet ports, it might run a firewall, a web server, or a database server and so on. Why do we need to configure all these metrics? + +**Netdata** has been designed to auto-detect everything. Of course you can enable, tweak or disable things. But by default, if **netdata** can retrieve `/server-status` from an web server you run on your linux box, it will automatically collect all performance metrics. This happens for apache, squid, nginx, mysql, opensips, etc. It will also automatically collect all available system values for CPU, memory, disks, network interfaces, QoS (with labels if you also use [FireQOS](http://firehol.org)), etc. Even for applications that do not offer performance metrics, it will automatically group the whole process tree and provide metrics like CPU usage, memory allocated, opened files, sockets, disk activity, swap activity, etc per application group. + +Netdata supports plenty of [configuration](../daemon/config/). However, we have done everything we can to allow netdata to auto-detect as much as possible. + +Even netdata plugins are designed to support configuration-less operation. So, you just install and run netdata. You will need to configure something only if it cannot be auto-detected. + +> Take any performance monitoring solution and try to troubleshoot a performance problem. At the end of the day you will have to ssh to the server to understand what exactly is happening. You will have to use `iostat`, `iotop`, `vmstat`, `top`, `iperf`, `ethtool` and probably a few dozen more console tools to figure it out. + +With **netdata**, this need is eliminated significantly. Of course you will ssh. Just not for monitoring performance. + +If you install **netdata** you will prefer it over the console tools. **Netdata** visualizes the data, while the console tools just show their values. The detail is the same - I have spent pretty much time reading the source code of the console tools, to figure out what needs to do done in netdata, so that the data, the values, will be the same. Actually, **netdata** is more precise than most console tools, it will interpolate all collected values to second boundary, so that even if something took a few microseconds more to be collected, netdata will correctly estimate the per second value. + +**Netdata** visualizes data in ways you cannot even imagine on a console. It allows you to see the present in real-time, much like the console tools, but also the recent past, compare different metrics with each other, zoom in to see the recent past in detail, or zoom out to have a helicopter view of what is happening in longer durations, build custom dashboards with just the charts you need for a specific purpose. + +Most engineers that install netdata, ssh to the server to tweak system or application settings and at the same time they monitor the result of the new settings in **netdata** on their browser. + +## Per second data collection and visualization + +**Per second data collection and visualization** is usually only available in dedicated console tools, like `top`, `vmstat`, `iostat`, etc. Netdata brings per second data collection and visualization to all applications, accessible through the web. + +*You are not convinced per second data collection is important?* +**Click** this image for a demo: + +[](http://netdata.firehol.org/demo2.html) + +## Realtime monitoring + +> Any performance monitoring solution that does not go down to per second collection and visualization of the data, is useless. It will make you happy to have it, but it will not help you more than that. + +Visualizing the present in **real-time and in great detail**, is the most important value a performance monitoring solution should provide. The next most important is the last hour, again per second. The next is the last 8 hours and so on, up to a week, or at most a month. In my 20+ years in IT, I needed just once or twice to look a year back. And this was mainly out of curiosity. + +Of course real-time monitoring requires resources. **netdata** is designed to be very efficient: + +1. collecting performance data is a repeating process - you do the same thing again and again. **Netdata** has been designed to learn from each iteration, so that the next one will be faster. It learns the sizes of files (it even keeps them open when it can), the number of lines and words per line they contain, the sizes of the buffers it needs to process them, etc. It adapts, so that everything will be as ready as possible for the next iteration. +2. internally, it uses hashes and indexes (b-trees), to speed up lookups of metrics, charts, dimensions, settings. +3. it has an in-memory round robin database based on a custom floating point number that allows it to pack values and flags together, in 32 bits, to lower its memory footprint. +4. its internal web server is capable of generating JSON responses from live performance data with speeds comparable to static content delivery (it does not use `printf`, it is actually 11 times faster than in generating JSON compared to `printf`). + +**Netdata** will use some CPU and memory, but it **will not produce any disk I/O at all**, apart its logs (which you can disable if you like). + +Most servers should have plenty of CPU resources (I consider a hardware upgrade or application split when a server averages around 40% CPU utilization at the peak hour). Even if a server has limited CPU resources available, you can just lower the data collection frequency of **netdata**. Going from per second to every 2 seconds data collection, will cut the **netdata** CPU requirements in half and you will still get charts that are just 2 seconds behind. + +The same goes for memory. If you just keep an hour of data (which is perfect for performance troubleshooting), you will most probably need 15-20MB. You can also enable the kernel de-duper (Kernel Same-Page Merging) and **netdata** will offer to it all its round robin database. KSM can free 20-60% of the memory used by **netdata** (guess why: there are a lot of metrics that are always zero or just constant). + +When netdata runs on modern computers (even on CELERON processors), most chart queries are replied in less than 3 milliseconds! **Not seconds, MILLISECONDS!** Less than 3 milliseconds for calculating the chart, generating JSON text, compressing it and sending it to your web browser. Timings are logged in netdata's `access.log` for you to examine. + +Netdata is written in plain `C` and the key system plugins are written in `C` too. Its speed can only be compared to the native console system administration tools. + +You can also stress test your netdata installation by running the script `tests/stress.sh` found in the distribution. Most modern server hardware can serve more than 300 chart refreshes per second per core. A raspberry pi 2, can serve 300+ chart refreshes per second utilizing all of its 4 cores. + + +## No disk I/O at all + +Netdata does not use any disk I/O, apart from its logs and even these can be disabled. + +Netdata will use some memory (you size it, check [[Memory Requirements]] and CPU (below 2% of a single core for the daemon, plugins may require more, check [[Performance]]), but normally your systems should have plenty of these resources available and spare. + +The design goal of **NO DISK I/O AT ALL** effectively means netdata will not disrupt your applications. + +## No root access + +You don't need to run netdata as root. If started as root, netdata will switch to the `netdata` user (or any other user given in its configuration or command line argument). + +There are a few plugins that in order to collect values need root access. These (and only these) are setuid to root. + +## Visualizes QoS + +Netdata visualizes `tc` QoS classes automatically. If you also use FireQOS, it will also collect interface and class names. + +Check this animated GIF (generated with [ScreenToGif](https://github.com/NickeManarin/ScreenToGif)): + + + +## Embedded web server + +> Most solutions require dedicated servers to actually use the monitoring console. To my perspective, this is totally unneeded for performance monitoring. All of us have a spectacular tool on our desktops, that allows us to connect in real time to any server in the world: **the web browser**. It shouldn't be so hard to use the same tool to connect in real-time to all our servers. + +With **netdata**, there is no need to centralize anything for performance monitoring. You view everything directly from their source. No need to run something else to access netdata. Of course you can use a firewall, or a reverse proxy, to limit access to it. But for most systems, inside your DMZ, just running it will be enough. + +Still, with **netdata** you can build dashboards with charts from any number of servers. And these charts will be connected to each other much like the ones that come from the same server. You will hover on one and all of them will show the relative value for the selected timestamp. You will zoom or pan one and all of them will follow. **Netdata** achieves that because the logic that connects the charts together is at the browser, not the server, so that all charts presented on the same page are connected, no matter where they come from. + +## Performance monitoring, scaled properly + +"Properly"? What is "properly"? + +We know software solutions can **scale up** (i.e. you replace its resources with bigger ones), or **scale out** (i.e. you add more smaller resources to it). In both cases, to get more of it, you need to supply **more resources**. + +So, what is "scaled properly"? + +Traditionally, monitoring solutions centralize all metric data to provide unified dashboards across all servers. So, you install agents on all your servers to collect system and application metrics which are then sent to a central place for storage and processing. Depending on the solution you use, the central place can either **scale up** or **scale out** (or a mix of the two). + +"Scaled properly" is something completely different. "Scaled properly" minimizes the need for a "central place", so that **there is nothing to be scaled**! + +Wait a moment! You cannot take out the "central place" of a monitoring solution! + +Yes, we can! well... most of it, but before explaining how, let's see what happens today: + +Monitoring solutions are a key component for any online service. These solutions usually consume considerable amount of resources. This is true for both "scale-up" and "scale-out" solutions. These resources require maintenance and administration too. To balance the resources required, these monitoring solutions follow a few simple rules: + +1. The number of metrics collected per server is limited. They collect CPU, RAM, DISK, NETWORK metrics and a few application metrics. + +2. The data collection frequency of each metric is also very low, at best it is once every 10 or 15 seconds, at worst every 5 or 10 mins. + +Due to all the above, most centralized monitoring solutions are usually good for alarms and **statistics of past performance**. The alarms usually trigger every 1 to 5 minutes and you get a few low-resolution charts about the past performance of your servers. + +Well... there is something wrong in this approach! Can you see it? + +Let's see the netdata approach: + +1. Data collection happens **per second**. This allows true real-time performance monitoring. + +2. **Thousands of metrics** per server and application are collected, **every single second**. The number of metrics collected is not a problem. + +3. Data do not leave the server they are collected. Data are not centralized, so the need for a huge central place that will process and store gazillions of data is not needed. + + > Ok, I hear a few of you complaining already - you will find out... patience... + +4. netdata does not use any DISK I/O while running (apart its log files - and even these can be disabled) and netdata runs with the lowest possible process priority, so that **your applications will never be affected by it**. + +5. Each netdata is standalone. Your web browser connects directly to each server to present real-time dashboards. The charts are so snappy, so real-time, so fast that we can call netdata, **a console killer for performance monitoring**. + +The charting libraries **netdata** uses, are the fastest possible ([Dygraphs](http://dygraphs.com/) do make the difference!) and **netdata** respects browser resources. Data are just rendered on a canvas. No processing in javascript at all. + +6. netdata is very efficient: just 2% of a single core is required and some RAM, and you can actually control how much of both you want to allocate to it. + + +Server side, chart data generation scales pretty well. You can expect 400+ chart refreshes per second per core on modern hardware. For a page with 10 charts visible (the page may have hundreds, but only the visible are refreshed), just a tiny fraction of a single CPU core will be used for servicing them. Even these refreshes stop when you switch tabs on your browser, you focus on another window, scroll to a part of the page without charts, zoom or pan a chart. And of course the **netdata** server runs with the lowest possible process priority, so that your production environment, your applications, will not be slowed down by the netdata server. + +7. netdata dashboards can be multi-server (check: [http://my-netdata.io](http://my-netdata.io)) - your browser connects to each netdata server directly. + +So, using netdata, your monitoring infrastructure is embedded on each server, limiting significantly the need of additional resources. netdata is very resource efficient and utilizes server resources that already exist and are spare (on each server). + +Of course, there are a few issues that need to be addressed with this approach: + +1. We need an index of all netdata installations we have +2. We need a place to handle notifications and alarms +3. We need a place to save statistics of past performance + +Our approach uses the netdata [registry](../registry/). The registry solves the problem of maintaining a list of all the netdata installations we have. It does this transparently, without any configuration. It tracks the netdata servers your web browser has visited and bookmarks them at the `my-netdata` menu. + +Every netdata can be a registry. You can use the global one we provided for free, or pick one of your netdata servers and turn it to a registry for your network. diff --git a/doc/a-github-star-is-important.md b/doc/a-github-star-is-important.md new file mode 100644 index 000000000..c00fba300 --- /dev/null +++ b/doc/a-github-star-is-important.md @@ -0,0 +1,13 @@ +# A GitHub start is important + +**GitHub stars** allow netdata to expand its reach, its community, especially attract people with skills willing to contribute to it. + +Compared to its first release, netdata is now **twice as fast**, has all its bugs settled and a lot more functionality.

Normally, you don't want to disable this. You can disable individual functions of it at the next section. +`tc`|monitoring network interfaces QoS (tc classes) +`idlejitter`|internal plugin (written in C) that attempts show if the systems starved for CPU. Disabling it will eliminate a thread. +`cgroups`|monitoring linux containers. Most probably you are not going to need it. This will also eliminate another thread. +`checks`|a debugging plugin, which is disabled by default. +`apps`|a plugin that monitors system processes. It is very complex and heavy (heavier than the netdata daemon), so if you don't need to monitor the process tree, you can disable it. +`charts.d`|BASH plugins (squid, nginx, mysql, etc).

CPU utilization + +If after disabling the plugins you don't need, netdata still uses a lot of CPU without any clients accessing the dashboard, try lowering its data collection frequency. Going from "once per second" to "once every two seconds" will not have a significant difference on the user experience, but it will cut the CPU resources required **in half**. + +To set the update frequency, edit `/etc/netdata/netdata.conf` and set: + +``` +[global] + update every = 2 +``` + +You may have to increase this to 5 or 10 if the CPU of the device is weak. + +Keep in mind this will also force dashboard chart refreshes to happen at the same rate.

Lower memory requirements + +You can set the default size of the round robin database for all charts, using: + +``` +[global] + history = 600 +``` + +The units for history is `[global].update every` seconds. So if `[global].update every = 6` and `[global].history = 600`, you will have an hour of data ( 6 x 600 = 3.600 ), which will store 600 points per dimension, one every 6 seconds. + +Check also [[Memory Requirements]] for directions on calculating the size of the round robin database. + +--- + +## 7.

For each source, netdata uses a plugin that connects to the source (or reads the relative files produced by the source), receives raw data and processes them to calculate the metrics shown on netdata dashboards. + +Even if netdata plugins connect to your database server, or read your application log file to collect raw data, the product of this data collection process is always a number of **chart metadata and metric values** (summarized data for dashboard visualization). All netdata plugins (internal to the netdata daemon, and external ones written in any computer language), convert raw data collected into metrics, and only these metrics are stored in netdata databases, sent to upstream netdata servers, or archived to backend time-series databases. + +> The **raw data** collected by netdata, do not leave the host they are collected. **The only data netdata exposes are chart metadata and metric values.** + +This means that netdata can safely be used in environments that require the highest level of data isolation (like PCI Level 1). + +## your systems are safe with netdata + +We are very proud that **the netdata daemon runs as a normal system user, without any special privileges**. This is quite an achievement for a monitoring system that collects all kinds of system and application metrics. + +There are a few cases however that raw source data are only exposed to processes with escalated privileges. To support these cases, netdata attempts to minimize and completely isolate the code that runs with escalated privileges. + +So, netdata **plugins**, even those running with escalated capabilities or privileges, perform a **hard coded data collection job**. They do not accept commands from netdata. The communication is strictly **unidirectional**: from the plugin towards the netdata daemon. The original application data collected by each plugin do not leave the process they are collected, are not saved and are not transferred to the netdata daemon. The communication from the plugins to the netdata daemon includes only chart metadata and processed metric values. + +netdata slaves streaming metrics to upstream netdata servers, use exactly the same protocol local plugins use. The raw data collected by the plugins of slave netdata servers are **never leaving the host they are collected**. The only data appearing on the wire are chart metadata and metric values. This communication is also **unidirectional**: slave netdata servers never accept commands from master netdata servers. + +## netdata is read-only + +netdata **dashboards are read-only**. Dashboard users can view and examine metrics collected by netdata, but cannot instruct netdata to do something other than present the already collected metrics. + +netdata dashboards do not expose sensitive information. Business data of any kind, the kernel version, O/S version, application versions, host IPs, etc are not stored and are not exposed by netdata on its dashboards. + +## netdata viewers authentication + +netdata is a monitoring system. It should be protected, the same way you protect all your admin apps. We assume netdata will be installed privately, for your eyes only. + +### why netdata should be protected + +Viewers will be able to get some information about the system netdata is running. This information is everything the dashboard provides. The dashboard includes a list of the services each system runs (the legends of the charts under the `Systemd Services` section), the applications running (the legends of the charts under the `Applications` section), the disks of the system and their names, the user accounts of the system that are running processes (the `Users` and `User Groups` section of the dashboard), the network interfaces and their names (not the IPs) and detailed information about the performance of the system and its applications. + +This information is not sensitive (meaning that it is not your business data), but **it is important for possible attackers**. It will give them clues on what to check, what to try and in the case of DDoS against your applications, they will know if they are doing it right or not. + +Also, viewers could use netdata itself to stress your servers. Although the netdata daemon runs unprivileged, with the minimum process priority (scheduling priority `idle` - lower than nice 19) and adjusts its OutOfMemory (OOM) score to 1000 (so that it will be first to be killed by the kernel if the system starves for memory), some pressure can be applied on your systems if someone attempts a DDoS against netdata. + +### protect netdata from the internet + +netdata is a distributed application. Most likely you will have many installations of it. Since it is distributed and you are expected to jump from server to server, there is very little usability to add authentication local on each netdata. + +Until we add a distributed authentication method to netdata, you have the following options: + +#### expose netdata only in a private LAN + +If your organisation has a private administration and management LAN, you can bind netdata on this network interface on all your servers. This is done in `netdata.conf` with these settings: + +``` +[web] + bind to = 10.1.1.1:19999 localhost:19999 +``` + +You can bind netdata to multiple IPs and ports. If you use hostnames, netdata will resolve them and use all the IPs (in the above example `localhost` usually resolves to both `127.0.0.1` and `::1`). + +**This is the best and the suggested way to protect netdata**. Your systems **should** have a private administration and management LAN, so that all management tasks are performed without any possibility of them being exposed on the internet. + +For cloud based installations, if your cloud provider does not provide such a private LAN (or if you use multiple providers), you can create a virtual management and administration LAN with tools like `tincd` or `gvpe`. These tools create a mesh VPN allowing all servers to communicate securely and privately. Your administration stations join this mesh VPN to get access to management and administration tasks on all your cloud servers. + +For `gvpe` we have developed a [simple provisioning tool](https://github.com/netdata/netdata-demo-site/tree/master/gvpe) you may find handy (it includes statically compiled `gvpe` binaries for Linux and FreeBSD, and also a script to compile `gvpe` on your Mac). We use this to create a management and administration LAN for all netdata demo sites (spread all over the internet using multiple hosting providers). + +--- + +In netdata v1.9+ there is also access list support, like this: + +``` +[web] + bind to = * + allow connections from = localhost 10.* 192.168.* +``` + + +#### use an authenticating web server in proxy mode + +Use **one nginx** (or one apache) server to provide authentication in front of **all your netdata servers**. So, you will be accessing all your netdata with URLs like `http://nginx.host/netdata/{NETDATA_HOSTNAME}/` and authentication will be shared among all of them (you will sign-in once for all your servers). Check [this wiki page for more information on configuring nginx for such a setup](Running-behind-nginx.md#netdata-via-nginx). + +To use this method, you should firewall protect all your netdata servers, so that only the nginx IP will allowed to directly access netdata. To do this, run this on each of your servers (or use your firewall manager): + +```sh +NGINX_IP="1.2.3.4" +iptables -t filter -I INPUT -p tcp --dport 19999 \! -s ${NGINX_IP} -m conntrack --ctstate NEW -j DROP +``` +_commands to allow direct access to netdata from an nginx proxy_ + +The above will prevent anyone except your nginx server to access a netdata dashboard running on the host. + +For netdata v1.9+ you can also use `netdata.conf`: + +``` +[web] + allow connections from = localhost 1.2.3.4 +``` + +Of course you can add more IPs. + +For netdata prior to v1.9, if you want to allow multiple IPs, use this: + +```sh +# space separated list of IPs to allow access netdata +NETDATA_ALLOWED="1.2.3.4 5.6.7.8 9.10.11.12" +NETDATA_PORT=19999 + +# create a new filtering chain || or empty an existing one named netdata +iptables -t filter -N netdata 2>/dev/null || iptables -t filter -F netdata +for x in ${NETDATA_ALLOWED} +do + # allow this IP + iptables -t filter -A netdata -s ${x} -j ACCEPT +done + +# drop all other IPs +iptables -t filter -A netdata -j DROP + +# delete the input chain hook (if it exists) +iptables -t filter -D INPUT -p tcp --dport ${NETDATA_PORT} -m conntrack --ctstate NEW -j netdata 2>/dev/null + +# add the input chain hook (again) +# to send all new netdata connections to our filtering chain +iptables -t filter -I INPUT -p tcp --dport ${NETDATA_PORT} -m conntrack --ctstate NEW -j netdata +``` +_script to allow access to netdata only from a number of hosts_ + +You can run the above any number of times. Each time it runs it refreshes the list of allowed hosts. + +#### other methods + +Of course, there are many more methods you could use to protect netdata: + +- bind netdata to localhost and use `ssh -L 19998:127.0.0.1:19999 remote.netdata.ip` to forward connections of local port 19998 to remote port 19999. This way you can ssh to a netdata server and then use `http://127.0.0.1:19998/` on your computer to access the remote netdata dashboard. + +- If you are always under a static IP, you can use the script given above to allow direct access to your netdata servers without authentication, from all your static IPs. + +- install all your netdata in **headless data collector** mode, forwarding all metrics in real-time to a master netdata server, which will be protected with authentication using an nginx server running locally at the master netdata server. This requires more resources (you will need a bigger master netdata server), but does not require any firewall changes, since all the slave netdata servers will not be listening for incoming connections. + +## registry or how to not send any information to a third party server + +The default configuration uses a public registry under registry.my-netdata.io (more information about the registry here: [mynetdata-menu-item](../registry/) ).

This does not work, as the chroot environment does not have access to `/proc`, and therefore exposes very few metrics to netdata. Additionally, [this issue](https://github.com/SynoCommunity/spksrc/issues/2758), still open as of 2018/06/24, indicates that the Debian Chroot package is not suitable for DSM versions greater than version 5 and may corrupt system libraries and render the NAS unable to boot. + +The good news is that the 64-bit static installer works fine if your NAS is one that uses the amd64 architecture. It will install the content into `/opt/netdata`, making future removal safe and simple. + +###### Additional Work + +When netdata is first installed, it will run as _root_. This may or may not be acceptable for you, and since other installations run it as the _netdata_ user, you might wish to do the same. This requires some extra work: + +1. Creat a group `netdata` via the Synology group interface. Give it no access to anything. +2. Create a user `netdata` via the Synology user interface. Give it no access to anything and a random password. Assign the user to the `netdata` group. Netdata will chuid to this user when running. +3. Change ownership of the following directories, as defined in [Netdata Security](../doc/netdata-security.md#netdata-security): + +``` +$ chown -R root:netdata /opt/netdata/usr/share/netdata +$ chown -R netdata:netdata /opt/netdata/var/lib/netdata /opt/netdata/var/cache/netdata +$ chown -R netdata:root /opt/netdata/var/log/netdata +``` + +Additionally, as of 2018/06/24, the netdata installer doesn't recognize DSM as an operating system, so no init script is installed. You'll have to do this manually: + +1. Add [this file](https://gist.github.com/oskapt/055d474d7bfef32c49469c1b53e8225f) as `/etc/rc.netdata`. Make it executable with `chmod 0755 /etc/rc.netdata`. +2.

Check [Creating Badges](../../api/badges/) for more information on badges. + +So, let's create a table and add this badge for both our web servers: + + + +Now we get this: + + + +### Add a netdata chart + +The simplest form of a chart is this (it adds the chart `web_log_nginx_netdata.response_statuses`, using 100% of the width, 150px height, and the last 10 minutes of data): + +```html +<div + data-netdata="web_log_nginx_netdata.response_statuses" + data-width="100%" + data-height="150px" + data-before="0" + data-after="-600" +></div> +``` + +Add this to `html` block on confluence: + + + +And you will get this: + + + +> This chart is **alive**, fully interactive. You can drag it, pan it, zoom it, etc like you do on netdata dashboards! + +Of course this too big. We need something smaller to add inside the table. Let's try this: + +```html +<div + data-netdata="web_log_nginx_netdata.response_statuses" + data-legend="false" + data-dygraph-yaxislabelwidth="35" + data-dygraph-ypixelsperlabel="8" + data-after="-600" + data-before="0" + data-title="" + data-height="100px" + data-width="300px" +></div> +``` + +The chart name is shown on all netdata charts, so just copy it from a netdata dashboard. + +We will fetch the same chart from both servers. To define the server we also added `data-host=` with the URL of each server, like this (we also added `<br/>` for a newline between the badge and the chart): + + + +Which gives us this: + + + +Note the color difference. This is because netdata automatically hides dimensions that are just zero (the frankfurt server has only successful requests). To instruct netdata to disable this feature, we need to add another html fragment at the bottom of the page (make sure this is added after loading `dashboard.js`). So we edit the first block we added, and append a new `<script>` section to it: + + +```html +<script> +// don't load bootstrap - confluence does not need this +var netdataNoBootstrap = true; + +// select the web notifications to show on this dashboard +// var netdataShowAlarms = true; +// var netdataAlarmsRecipients = [ 'sysadmin', 'webmaster' ]; +</script> + +<script src="https://london.my-netdata.io/dashboard.js"></script> + +<script> +// do not hide dimensions with just zeros +NETDATA.options.current.eliminate_zero_dimensions = false; +</script> +``` + +Now they match: + + + +#### more options + +If you want to change the colors append `data-colors="#001122 #334455 #667788"`. The colors will be used for the dimensions top to bottom, as shown on a netdata dashboard. Keep in mind the default netdata dashboards hide by default all dimensions that are just zero, so enable them at the dashboard settings to see them all. + +You can get a percentage chart, by adding these on these charts: + +```html + data-append-options="percentage" + data-decimal-digits="0" + data-dygraph-valuerange="[0, 100]" + data-dygraph-includezero="true" + data-units="%" +``` + +The first line instructs netdata to calculate the percentage of each dimension, the second strips any fractional digits, the third instructs the charting library to size the chart from 0 to 100, the next one instructs it to include 0 in the chart and the last changes the units of the chart to `%`. This is how it will look: + + + +You can make any number of charts have common min and max on the y-range by adding `common-min="NAME"` and `common-max="NAME"`, where `NAME` is anything you like. Keep in mind for best results all the charts with the same `NAME` should be visible at once, otherwise a not-visible chart will influence the range and until it is updated the range will not adapt. + +### Add gauges + +Let's now add a few gauges. The chart we added has several dimensions: `success`, `error`, `redirect`, `bad` and `other`. + +Let's say we want to add 2 gauges: + +1. `success` and `redirect` together, in blue +2. `error`, `bad` and `other` together, in orange + +We will add the following for each server. We have enclosed them in another a `<div>` because Confluence will wrap them if the page width is not enough to fit them. With that additional `<div>` they will always be next to each other. + +```html +<div style="width: 300px; text-align: center;"> +<div + data-netdata="web_log_nginx_netdata.response_statuses" + data-host="https://london.my-netdata.io" + data-dimensions="success,redirect" + data-chart-library="gauge" + data-title="Good" + data-units="requests/s" + data-gauge-adjust="width" + data-width="120" + data-before="0" + data-after="-600" + data-points="600" + data-common-max="response_statuses" + data-colors="#007ec6" + data-decimal-digits="0" + ></div><div + data-netdata="web_log_nginx_netdata.response_statuses" + data-host="https://london.my-netdata.io" + data-dimensions="error,bad,other" + data-chart-library="gauge" + data-title="Bad" + data-units="requests/s" + data-gauge-adjust="width" + data-width="120" + data-before="0" + data-after="-600" + data-points="600" + data-common-max="response_statuses" + data-colors="#97CA00" + data-decimal-digits="0" + ></div> +</div> +``` + +Adding the above will give you this: + + + + +### Final source - for the confluence source editor + +If you enable the source editor of Confluence, you can paste the whole example (implementing the first image on this post and demonstrating everything discussed on this page): + +```html +<p class="auto-cursor-target">Monitoring the health of the

Keep in mind more javascript modules may be loaded (every chart library is a different javascript file, that is loaded on first use). + +### Prevent dashboard.js from starting chart refreshes + +If your web page is not static and you plan to add charts using javascript, you can tell `dashboard.js` not to start processing charts immediately after loaded, by adding this fragment before loading it: + +```html +<script>var netdataDontStart = true;</script> +``` + +The above, will inform the `dashboard.js` to load everything, but not process the web page until you tell it to. +You can tell it to start processing the page, by running this javascript code: + +```js +NETDATA.start(); +``` + +Be careful not to call the `NETDATA.start()` multiple times. Each call to this function will spawn a new thread that will start refreshing the charts. + +If, after calling `NETDATA.start()` you need to update the page (or even get your javascript code synchronized with `dashboard.js`), you can call (after you loaded `dashboard.js`): + +```js +NETDATA.pause(function() { + // ok, it is paused + + // update the DOM as you wish + + // and then call this to let the charts refresh: + NETDATA.unpause(); +}); +``` + +### The default netdata server + +`dashboard.js` will attempt to auto-detect the URL of the netdata server it is loaded from, and set this server as the default netdata server for all charts. + +If you need to set any other URL as the default netdata server for all charts that do not specify a netdata server, add this before loading `dashboard.js`: + +```html +<script type="text/javascript">var netdataServer = "http://your.netdata.server:19999";</script> +``` + +--- + +# Adding charts + +To add charts, you need to add a `div` for each of them. Each of these `div` elements accept a few `data-` attributes: + +### The chart unique ID + +The unique ID of a chart is shown at the title of the chart of the default netdata dashboard. You can also find all the charts available at your netdata server with this URL: `http://your.netdata.server:19999/api/v1/charts` ([example](http://netdata.firehol.org/api/v1/charts)). + +To specify the unique id, use this: + +```html +<div data-netdata="unique.id"></div> +``` + +The above is enough for adding a chart. It most probably have the wrong visual settings though. Keep reading... + +### The duration of the chart + +You can specify the duration of the chart (how much time of data it will show) using: + +```html +<div data-netdata="unique.id" + data-after="AFTER_SECONDS" + data-before="BEFORE_SECONDS" + ></div> +``` + +`AFTER_SECONDS` and `BEFORE_SECONDS` are numbers representing a time-frame in seconds. + +The can be either: + +- **absolute** unix timestamps (in javascript terms, they are `new Date().getTime() / 1000`. Using absolute timestamps you can have a chart showing always the same time-frame. + +- **relative** number of seconds to now. To show the last 10 minutes of data, `AFTER_SECONDS` must be `-600` (relative to now) and `BEFORE_SECONDS` must be `0` (meaning: now). If you want the chart to auto-refresh the current values, you need to specify **relative** values. + +### Chart sizes + +You can set the size of the chart using this: + +```html +<div data-netdata="unique.id" + data-width="WIDTH" + data-height="HEIGHT" + ></div> +``` + +`WIDTH` and `HEIGHT` can be anything CSS accepts for width and height (e.g. percentages, pixels, etc). +Keep in mind that for certain chart libraries, `dashboard.js` may apply an aspect ratio to these. + +If you want `dashboard.js` to remember permanently (browser local storage) the dimensions of the chart (the user may resize it), you can add: `data-id="SETTINGS_ID"`, where `SETTINGS_ID` is anything that will be common for this chart across user sessions. + +### Netdata server + +Each chart can get data from a different netdata server. You can give per chart the netdata server using: + +```html +<div data-netdata="unique.id" + data-host="http://another.netdata.server:19999/" + ></div> +``` + +If you have ephemeral monitoring setup ([More info here](../../../streaming/#monitoring-ephemeral-nodes)) and have no direct access to the nodes dashboards, you can use the following: + +```html +<div data-netdata="unique.id" + data-host="http://yournetdata.server:19999/host/reported-hostname" + ></div> +``` +### Chart library + +The default chart library is `dygraph`.

If the chart shows 10 minutes of data (600 seconds), its update frequency is 1 second, and the chart width is 1800 pixels, then `dashboard.js` will request from the netdata server: 10 minutes of data, represented in 600 points, and the chart will be refreshed per second. If the user resizes the window so that the chart becomes 600 pixels wide, then `dashboard.js` will request the same 10 minutes of data, represented in 200 points and the chart will be refreshed once every 3 seconds. + +If you need to have a fixed number of points in the data source retrieved from the netdata server, you can set: + +```html +<div data-netdata="unique.id" + data-points="DATA_POINTS" + ></div> +``` + +Where `DATA_POINTS` is the number of points you need. + +You can also overwrite the pixels-per-point per chart using this: + +```html +<div data-netdata="unique.id" + data-pixels-per-point="PIXELS_PER_POINT" + ></div> +``` + +Where `PIXELS_PER_POINT` is the number of pixels each data point should occupy. + +### Data grouping method + +Netdata supports **average** (the default), **sum** and **max** grouping methods. The grouping method is used when the netdata server is requested to return fewer points for a time-frame, compared to the number of points available. + +You can give it per chart, using: + +```html +<div data-netdata="unique.id" + data-method="max" + ></div> +``` + +### Changing rates + +Netdata can change the rate of charts on the fly. So a charts that shows values **per second** can be turned to **per minute** (or any other, e.g. **per 10 seconds**), with this: + +```html +<div data-netdata="unique.id" + data-method="average" + data-gtime="60" + data-units="per minute" + ></div> +``` + +The above will provide the average rate per minute (60 seconds). +Use 60 for `/minute`, 3600 for `/hour`, 86400 for `/day` (provided you have that many data). + +- The `data-gtime` setting does not change the units of the chart. You have to change them yourself with `data-units`. +- This works only for `data-method="average"`. +- netdata may aggregate multiple points to satisfy the `data-points` setting. For example, you request `per minute` but the requested number of points to be returned are not enough to report every single minute. In this case netdata will sum the `per second` raw data of the database to find the `per minute` for every single minute and then **average** them to find the **average per minute rate of every X minutes**. So, it works as if the data collection frequency was per minute. + +### Selecting dimensions + +By default, `dashboard.js` will show all the dimensions of the chart. +You can select specific dimensions using this: + +```html +<div data-netdata="unique.id" + data-dimensions="dimension1,dimension2,dimension3,..." + ></div> +``` + +netdata supports coma (` , `) or pipe (` | `) separated [simple patterns](../../../libnetdata/simple_pattern/) for dimensions. By default it searches for both dimension IDs and dimension NAMEs. You can control the target of the match with: `data-append-options="match-ids"` or `data-append-options="match-names"`. Spaces in `data-dimensions=""` are matched in the dimension names and IDs. + +### Chart title + +You can overwrite the title of the chart using this: + +```html +<div data-netdata="unique.id" + data-title="my super chart" + ></div> +``` + +### Chart units + +You can overwrite the units of measurement of the dimensions of the chart, using this: + +```html +<div data-netdata="unique.id" + data-units="words/second" + ></div> +``` + +### Chart colors + +`dashboard.js` has an internal palette of colors for the dimensions of the charts. +You can prepend colors to it (so that your will be used first) using this: + +```html +<div data-netdata="unique.id" + data-colors="#AABBCC #DDEEFF ..." + ></div> +``` + +### Extracting dimension values + +`dashboard.js` can update the selected values of the chart at elements you specify. For example, let's assume we have a chart that measures the bandwidth of eth0, with 2 dimensions `in` and `out`. You can use this: + +```html +<div data-netdata="net.eth0" + data-show-value-of-in-at="eth0_in_value" + data-show-value-of-out-at="eth0_out_value" + ></div> + +My eth0 interface, is receiving <span id="eth0_in_value"></span> +and transmitting <span id="eth0_out_value"></span>. +``` + +### Hiding the legend of a chart + +On charts that by default have a legend managed by `dashboard.js` you can remove it, using this: + +```html +<div data-netdata="unique.id" + data-legend="no" + ></div> +``` + +### API options + +You can append netdata **[[REST API v1]]** data options, using this: + +```html +<div data-netdata="unique.id" + data-append-options="absolute,percentage" + ></div> +``` + +A few useful options are: + +- `absolute` to show all values are absolute (i.e. turn negative dimensions to positive) +- `percentage` to express the values as a percentage of the chart total (so, the values of the dimensions are added, and the sum of them if expressed as a percentage of the sum of all dimensions) +- `unaligned` to prevent netdata from aligning the charts (e.g. when requesting 60 seconds aggregation per point, netdata returns chart data aligned to XX:XX:00 to XX:XX:59 - similarly for hours, days, etc - the `unaligned` option disables this feature) +- `match-ids` or `match-names` is used to control what `data-dimensions=` will match. + +### Chart library performance + +`dashboard.js` measures the performance of the chart library when it renders the charts. You can specify an element ID you want this information to be visualized, using this: + +```html +<div data-netdata="unique.id" + data-dt-element-name="measurement1" + ></div> + +refreshed in <span id="measurement1"></span> milliseconds! +``` + +### Syncing charts y-range + +If you give the same `data-common-max="NAME"` to 2+ charts, then all of them will share the same max value of their y-range. If one spikes, all of them will be aligned to have the same scale. This is done for the cpu interrupts and and cpu softnet charts at the dashboard and also for the `gauge` and `easypiecharts` of the netdata home page. + +```html +<div data-netdata="chart1" + data-common-max="chart-group-1" + ></div> + +<div data-netdata="chart2" + data-common-max="chart-group-1" + ></div> +``` + +The same functionality exists for `data-common-min`. + +### Syncing chart units + +netdata dashboards support auto-scaling of units. So, `MB` can become `KB`, `GB`, etc dynamically, based on the value to be shown. + +Giving the same `NAME` with `data-common-units="NAME"`, 2+ charts can be forced to always have the same units. + +```html +<div data-netdata="chart1" + data-common-units="chart-group-1" + ></div> + +<div data-netdata="chart2" + data-common-units="chart-group-1" + ></div> +``` + +### Setting desired units + +Charts can be scaled to specific units with `data-desired-units="UNITS"`.
