You can use the -configuration file - -```txt -[prometheus:exporter] - send charts matching = system.* -``` - -or the URL parameter `filter` in the `allmetrics` API call. - -```txt -http://localhost:19999/api/v1/allmetrics?format=shell&filter=system.* -``` - -### Operation modes - -Netdata supports three modes of operation for all exporting connectors: - -- `as-collected` sends to external databases the metrics as they are collected, in the units they are collected. - So, counters are sent as counters and gauges are sent as gauges, much like all data collectors do. For example, - to calculate CPU utilization in this format, you need to know how to convert kernel ticks to percentage. - -- `average` sends to external databases normalized metrics from the Netdata database. In this mode, all metrics - are sent as gauges, in the units Netdata uses. This abstracts data collection and simplifies visualization, but - you will not be able to copy and paste queries from other sources to convert units. For example, CPU utilization - percentage is calculated by Netdata, so Netdata will convert ticks to percentage and send the average percentage - to the external database. - -- `sum` or `volume`: the sum of the interpolated values shown on the Netdata graphs is sent to the external - database. So, if Netdata is configured to send data to the database every 10 seconds, the sum of the 10 values - shown on the Netdata charts will be used. - -Time-series databases suggest to collect the raw values (`as-collected`). If you plan to invest on building your -monitoring around a time-series database and you already know (or you will invest in learning) how to convert units -and normalize the metrics in Grafana or other visualization tools, we suggest to use `as-collected`. - -If, on the other hand, you just need long term archiving of Netdata metrics and you plan to mainly work with -Netdata, we suggest to use `average`. It decouples visualization from data collection, so it will generally be a lot -simpler. Furthermore, if you use `average`, the charts shown in the external service will match exactly what you -see in Netdata, which is not necessarily true for the other modes of operation. - -### Independent operation - -This code is smart enough, not to slow down Netdata, independently of the speed of the external database server. - -> ❗ You should keep in mind though that many exporting connector instances can consume a lot of CPU resources if they -> run their batches at the same time. You can set different update intervals for every exporting connector instance, -> but even in that case they can occasionally synchronize their batches for a moment. - -## Configuration - -Here are the configuration blocks for every supported connector. Your current `exporting.conf` file may look a little -different. - -You can configure each connector individually using the available [options](#options). The -`[graphite:my_graphite_instance]` block contains examples of some of these additional options in action. - -```conf -[exporting:global] - enabled = yes - send configured labels = no - send automatic labels = no - update every = 10 - -[prometheus:exporter] - send names instead of ids = yes - send configured labels = yes - send automatic labels = no - send charts matching = * - send hosts matching = localhost * - prefix = netdata - -[graphite:my_graphite_instance] - enabled = yes - destination = localhost:2003 - data source = average - prefix = Netdata - hostname = my-name - update every = 10 - buffer on failures = 10 - timeout ms = 20000 - send charts matching = * - send hosts matching = localhost * - send names instead of ids = yes - send configured labels = yes - send automatic labels = yes - -[prometheus_remote_write:my_prometheus_remote_write_instance] - enabled = yes - destination = localhost - remote write URL path = /receive - -[kinesis:my_kinesis_instance] - enabled = yes - destination = us-east-1 - stream name = netdata - aws_access_key_id = my_access_key_id - aws_secret_access_key = my_aws_secret_access_key - -[pubsub:my_pubsub_instance] - enabled = yes - destination = pubsub.googleapis.com - credentials file = /etc/netdata/pubsub_credentials.json - project id = my_project - topic id = my_topic - -[mongodb:my_mongodb_instance] - enabled = yes - destination = localhost - database = my_database - collection = my_collection - -[json:my_json_instance] - enabled = yes - destination = localhost:5448 - -[opentsdb:my_opentsdb_plaintext_instance] - enabled = yes - destination = localhost:4242 - -[opentsdb:http:my_opentsdb_http_instance] - enabled = yes - destination = localhost:4242 - username = my_username - password = my_password - -[opentsdb:https:my_opentsdb_https_instance] - enabled = yes - destination = localhost:8082 -``` - -### Sections - -- `[exporting:global]` is a section where you can set your defaults for all exporting connectors -- `[prometheus:exporter]` defines settings for Prometheus exporter API queries (e.g.: - `http://NODE:19999/api/v1/allmetrics?format=prometheus&help=yes&source=as-collected`). -- `[<type>:<name>]` keeps settings for a particular exporting connector instance, where: - - `type` selects the exporting connector type: graphite | opentsdb:telnet | opentsdb:http | - prometheus_remote_write | json | kinesis | pubsub | mongodb. For graphite, opentsdb, - json, and prometheus_remote_write connectors you can also use `:http` or `:https` modifiers - (e.g.: `opentsdb:https`). - - `name` can be arbitrary instance name you chose. - -### Options - -Configure individual connectors and override any global settings with the following options. - -- `enabled = yes | no`, enables or disables an exporting connector instance - -- `destination = host1 host2 host3 ...`, accepts **a space separated list** of hostnames, IPs (IPv4 and IPv6) and - ports to connect to. Netdata will use the **first available** to send the metrics. - - The format of each item in this list, is: `[PROTOCOL:]IP[:PORT]`. - - `PROTOCOL` can be `udp` or `tcp`. `tcp` is the default and only supported by the current exporting engine. - - `IP` can be `XX.XX.XX.XX` (IPv4), or `[XX:XX...XX:XX]` (IPv6). For IPv6 you can to enclose the IP in `[]` to - separate it from the port. - - `PORT` can be a number of a service name. If omitted, the default port for the exporting connector will be used - (graphite = 2003, opentsdb = 4242). - - Example IPv4: - -```conf - destination = 10.11.14.2:4242 10.11.14.3:4242 10.11.14.4:4242 -``` - - Example IPv6 and IPv4 together: - -```conf - destination = [ffff:...:0001]:2003 10.11.12.1:2003 -``` - - When multiple servers are defined, Netdata will try the next one when the previous one fails. - - Netdata also ships `nc-exporting.sh`, a script that can be used as a fallback exporting connector to save the - metrics to disk and push them to the time-series database when it becomes available again. It can also be used to - monitor / trace / debug the metrics Netdata generates. - - For the Kinesis exporting connector `destination` should be set to an AWS region (for example, `us-east-1`). - - For the MongoDB exporting connector `destination` should be set to a - [MongoDB URI](https://docs.mongodb.com/manual/reference/connection-string/). - - For the Pub/Sub exporting connector `destination` can be set to a specific service endpoint. - -- `data source = as collected`, or `data source = average`, or `data source = sum`, selects the kind of data that will - be sent to the external database. - -- `hostname = my-name`, is the hostname to be used for sending data to the external database server. By default this - is `[global].hostname`. - -- `prefix = Netdata`, is the prefix to add to all metrics. - -- `update every = 10`, is the number of seconds between sending data to the external database. Netdata will add some - randomness to this number, to prevent stressing the external server when many Netdata servers send data to the same - database. This randomness does not affect the quality of the data, only the time they are sent. - -- `buffer on failures = 10`, is the number of iterations (each iteration is `update every` seconds) to buffer data, - when the external database server is not available. If the server fails to receive the data after that many - failures, data loss on the connector instance is expected (Netdata will also log it). - -- `timeout ms = 20000`, is the timeout in milliseconds to wait for the external database server to process the data. - By default this is `2 * update_every * 1000`. - -- `send hosts matching = localhost *` includes one or more space separated patterns, using `*` as wildcard (any number - of times within each pattern). The patterns are checked against the hostname (the localhost is always checked as - `localhost`), allowing us to filter which hosts will be sent to the external database when this Netdata is a central - Netdata aggregating multiple hosts. A pattern starting with `!` gives a negative match. So to match all hosts named - `*db*` except hosts containing `*child*`, use `!*child* *db*` (so, the order is important: the first - pattern matching the hostname will be used - positive or negative). - -- `send charts matching = *` includes one or more space separated patterns, using `*` as wildcard (any number of times - within each pattern). The patterns are checked against both chart id and chart name. A pattern starting with `!` - gives a negative match. So to match all charts named `apps.*` except charts ending in `*reads`, use `!*reads - apps.*` (so, the order is important: the first pattern matching the chart id or the chart name will be used - - positive or negative). There is also a URL parameter `filter` that can be used while querying `allmetrics`. The URL - parameter has a higher priority than the configuration option. - -- `send names instead of ids = yes | no` controls the metric names Netdata should send to the external database. - Netdata supports names and IDs for charts and dimensions. Usually IDs are unique identifiers as read by the system - and names are human friendly labels (also unique). Most charts and metrics have the same ID and name, but in several - cases they are different: disks with device-mapper, interrupts, QoS classes, statsd synthetic charts, etc. - -- `send configured labels = yes | no` controls if host labels defined in the `[host labels]` section in `netdata.conf` - should be sent to the external database - -- `send automatic labels = yes | no` controls if automatically created labels, like `_os_name` or `_architecture` - should be sent to the external database - -## HTTPS - -Netdata can send metrics to external databases using the TLS/SSL protocol. Unfortunately, some of -them does not support encrypted connections, so you will have to configure a reverse proxy to enable -HTTPS communication between Netdata and an external database. You can set up a reverse proxy with -[Nginx](https://github.com/netdata/netdata/blob/master/docs/Running-behind-nginx.md). - -## Exporting engine monitoring - -Netdata creates five charts in the dashboard, under the **Netdata Monitoring** section, to help you monitor the health -and performance of the exporting engine itself: - -1. **Buffered metrics**, the number of metrics Netdata added to the buffer for dispatching them to the - external database server. - -2. **Exporting data size**, the amount of data (in KB) Netdata added the buffer. - -3. **Exporting operations**, the number of operations performed by Netdata. - -4. **Exporting thread CPU usage**, the CPU resources consumed by the Netdata thread, that is responsible for sending - the metrics to the external database server. - - - -## Exporting engine alerts - -Netdata adds 3 alerts: - -1. `exporting_last_buffering`, number of seconds since the last successful buffering of exported data -2. `exporting_metrics_sent`, percentage of metrics sent to the external database server -3. `exporting_metrics_lost`, number of metrics lost due to repeating failures to contact the external database server - - - - diff --git a/exporting/TIMESCALE.md b/exporting/TIMESCALE.md deleted file mode 100644 index 8ca61b75..00000000 --- a/exporting/TIMESCALE.md +++ /dev/null @@ -1,71 +0,0 @@ -<!-- -title: "Writing metrics to TimescaleDB" -description: "Send Netdata metrics to TimescaleDB for long-term archiving and further analysis." -custom_edit_url: "https://github.com/netdata/netdata/edit/master/exporting/TIMESCALE.md" -sidebar_label: "Writing metrics to TimescaleDB" -learn_status: "Published" -learn_rel_path: "Integrations/Export" ---> - -# Writing metrics to TimescaleDB - -Thanks to Netdata's community of developers and system administrators, and Mahlon Smith -([GitHub](https://github.com/mahlonsmith)/[Website](http://www.martini.nu/)) in particular, Netdata now supports -archiving metrics directly to TimescaleDB. - -What's TimescaleDB?

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: - -```sh -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. - -```sh -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](https://github.com/netdata/netdata/blob/master/packaging/installer/README.md), 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. - -<!-- candidate for reuse --> -```sh -wget -O /tmp/netdata-kickstart.sh https://my-netdata.io/kickstart.sh && sh /tmp/netdata-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_disk_space_GiB_average{chart="disk_space._run",dimension="avail",family="/run",mount_point="/run",filesystem="tmpfs",mount_root="/"} 0.0298195 1684951093000` -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_disk_space_GiB_average` has several labels: (`chart`, `family`, `dimension`, `mountt_point`, `filesystem`, `mount_root`). -This corresponds with disk space 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. - -```sh -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. - -```sh -yum install vim -y -``` - -You will also need `wget` and `curl` to download files and `sudo` if you are not root. - -```sh -yum install curl sudo wget -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. - -```sh -cd /tmp && curl -s https://api.github.com/repos/prometheus/prometheus/releases/latest \ -| grep "browser_download_url.*linux-amd64.tar.gz" \ -| cut -d '"' -f 4 \ -| wget -qi - - -mkdir /opt/prometheus - -sudo tar -xvf /tmp/prometheus-*linux-amd64.tar.gz -C /opt/prometheus --strip=1 -``` - -This should get Prometheus installed into the container. Let's test that we can run Prometheus and connect to it's web -interface. - -```sh -/opt/prometheus/prometheus --config.file=/opt/prometheus/prometheus.yml -``` - -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. - -```conf -netdata_disk_space_GiB_average{chart="disk_space._run",dimension="avail",family="/run",mount_point="/run",filesystem="tmpfs",mount_root="/"} 0.0298195 1684951093000 -``` - -Here our metric is `netdata_disk_space_GiB_average` and our common labels are `chart`, `family`, and `dimension`. The -last two values constitute the actual metric value for the metric type (gauge, counter, etc…). We also have specific -label for this chart named `mount_point`,`filesystem`, and `mount_root`. 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). - -```yaml -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: - -```sh -[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 homogeneous 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. - -```conf -# 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](https://github.com/netdata/netdata/blob/master/exporting/prometheus/README.md#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: - -```sh -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/exporting/aws_kinesis/Makefile.am b/exporting/aws_kinesis/Makefile.am deleted file mode 100644 index 161784b8..00000000 --- a/exporting/aws_kinesis/Makefile.am +++ /dev/null @@ -1,8 +0,0 @@ -# SPDX-License-Identifier: GPL-3.0-or-later - -AUTOMAKE_OPTIONS = subdir-objects -MAINTAINERCLEANFILES = $(srcdir)/Makefile.in - -dist_noinst_DATA = \ - README.md \ - $(NULL) diff --git a/exporting/aws_kinesis/README.md b/exporting/aws_kinesis/README.md deleted file mode 120000 index dbc98ac1..00000000 --- a/exporting/aws_kinesis/README.md +++ /dev/null @@ -1 +0,0 @@ -integrations/aws_kinesis.md

The examples provided in this document assume that you will be using Netdata as -a metrics endpoint, but the concepts apply as well to the remote write API method. - -### Understanding Netdata metrics - -#### Charts - -Each chart in Netdata has several properties (common to all its metrics): - -- `chart_id` - uniquely identifies a chart. - -- `chart_name` - a more human friendly name for `chart_id`, also unique. - -- `context` - this is the template of the chart. All disk I/O charts have the same context, all mysql requests charts - have the same context, etc. This is used for alert templates to match all the charts they should be attached to. - -- `family` groups a set of charts together. It is used as the submenu of the dashboard. - -- `units` is the units for all the metrics attached to the chart. - -#### Dimensions - -Then each Netdata chart contains metrics called `dimensions`. All the dimensions of a chart have the same units of -measurement, and are contextually in the same category (ie. the metrics for disk bandwidth are `read` and `write` and -they are both in the same chart). - -### Netdata data source - -Netdata can send metrics to Prometheus from 3 data sources: - -- `as collected` or `raw` - this data source sends the metrics to Prometheus as they are collected. No conversion is - done by Netdata. The latest value for each metric is just given to Prometheus. This is the most preferred method by - Prometheus, but it is also the harder to work with. To work with this data source, you will need to understand how - to get meaningful values out of them. - - The format of the metrics is: `CONTEXT{chart="CHART",family="FAMILY",dimension="DIMENSION"}`. - - If the metric is a counter (`incremental` in Netdata lingo), `_total` is appended the context. - - Unlike Prometheus, Netdata allows each dimension of a chart to have a different algorithm and conversion constants - (`multiplier` and `divisor`). In this case, that the dimensions of a charts are heterogeneous, Netdata will use this - format: `CONTEXT_DIMENSION{chart="CHART",family="FAMILY"}` - -- `average` - this data source uses the Netdata database to send the metrics to Prometheus as they are presented on - the Netdata dashboard. So, all the metrics are sent as gauges, at the units they are presented in the Netdata - dashboard charts. This is the easiest to work with. - - The format of the metrics is: `CONTEXT_UNITS_average{chart="CHART",family="FAMILY",dimension="DIMENSION"}`. - - When this source is used, Netdata keeps track of the last access time for each Prometheus server fetching the - metrics. This last access time is used at the subsequent queries of the same Prometheus server to identify the - time-frame the `average` will be calculated. - - So, no matter how frequently Prometheus scrapes Netdata, it will get all the database data. - To identify each Prometheus server, Netdata uses by default the IP of the client fetching the metrics. - - If there are multiple Prometheus servers fetching data from the same Netdata, using the same IP, each Prometheus - server can append `server=NAME` to the URL. Netdata will use this `NAME` to uniquely identify the Prometheus server. - -- `sum` or `volume`, is like `average` but instead of averaging the values, it sums them. - - The format of the metrics is: `CONTEXT_UNITS_sum{chart="CHART",family="FAMILY",dimension="DIMENSION"}`. All the - other operations are the same with `average`. - - To change the data source to `sum` or `as-collected` you need to provide the `source` parameter in the request URL. - e.g.: `http://your.netdata.ip:19999/api/v1/allmetrics?format=prometheus&help=yes&source=as-collected` - - Keep in mind that early versions of Netdata were sending the metrics as: `CHART_DIMENSION{}`. - -### Querying Metrics - -Fetch with your web browser this URL: - -`http://your.netdata.ip:19999/api/v1/allmetrics?format=prometheus&help=yes` - -_(replace `your.netdata.ip` with the ip or hostname of your Netdata server)_ - -Netdata will respond with all the metrics it sends to Prometheus. - -If you search that page for `"system.cpu"` you will find all the metrics Netdata is exporting to Prometheus for this -chart. `system.cpu` is the chart name on the Netdata dashboard (on the Netdata dashboard all charts have a text heading -such as : `Total CPU utilization (system.cpu)`.

You can change this in `netdata.conf`, like this: - -```conf -[prometheus:exporter] - prefix = netdata -``` - -It can also be changed from the URL, by appending `&prefix=netdata`. - -### Metric Units - -The default source `average` adds the unit of measurement to the name of each metric (e.g. `_KiB_persec`).

To get the metric names as they were -before v1.12, append to the URL `&oldunits=yes` - -### Accuracy of `average` and `sum` data sources - -When the data source is set to `average` or `sum`, Netdata remembers the last access of each client accessing Prometheus -metrics and uses this last access time to respond with the `average` or `sum` of all the entries in the database since -that. This means that Prometheus servers are not losing data when they access Netdata with data source = `average` or -`sum`. - -To uniquely identify each Prometheus server, Netdata uses the IP of the client accessing the metrics. If however the IP -is not good enough for identifying a single Prometheus server (e.g. when Prometheus servers are accessing Netdata -through a web proxy, or when multiple Prometheus servers are NATed to a single IP), each Prometheus may append -`&server=NAME` to the URL.
