-# Motivation
+## Pull Request Checklist for Node.js Plugins
+
+This is a generic checklist for submitting a new Node.js plugin for Netdata. It is by no means comprehensive.
+
+At minimum, to be buildable and testable, the PR needs to include:
+

Node.js is perfect for asynchronous operations. It is very fast and quite common (actually the whole web is based on it).
Since data collection is not a CPU intensive task, node.js is an ideal solution for it.

node.js is the fastest scripting language for collecting data. If your plugin needs to do a lot of work, compute values, etc, node.js is probably the best choice before moving to compiled code.

BASH is the simplest scripting language for collecting values. It is the less efficient though in terms of CPU resources. You can use it to collect data quickly, but extensive use of it might use a lot of system resources.
4. **C**
Of course, C is the most efficient way of collecting data. This is why netdata itself is written in C.

@@ -33,75 +32,45 @@ Performance monitoring for Linux disks is quite complicated. The main reason is
Hopefully, the Linux kernel provides many metrics that can provide deep insights of what our disks our doing. The kernel measures all these metrics on all layers of storage: **virtual disks**, **physical disks** and **partitions of disks**.
-Let's see the list of metrics provided by netdata for each of the above:
-
-### I/O bandwidth/s (kb/s)
-
-The amount of data transferred from and to the disk.
-
-### I/O operations/s
-
-The number of I/O operations completed.
-
-### Queued I/O operations
-
-The number of currently queued I/O operations. For traditional disks that execute commands one after another, one of them is being run by the disk and the rest are just waiting in a queue.
-
-### Backlog size (time in ms)
-
-The expected duration of the currently queued I/O operations.
-
-### Utilization (time percentage)
-
-The percentage of time the disk was busy with something. This is a very interesting metric, since for most disks, that execute commands sequentially, **this is the key indication of congestion**. A sequential disk that is 100% of the available time busy, has no time to do anything more, so even if the bandwidth or the number of operations executed by the disk is low, its capacity has been reached.
-
-Of course, for newer disk technologies (like fusion cards) that are capable to execute multiple commands in parallel, this metric is just meaningless.
-
-### Average I/O operation time (ms)
-
-The average time for I/O requests issued to the device to be served. This includes the time spent by the requests in queue and the time spent servicing them.
-
-### Average I/O operation size (kb)
-
-The average amount of data of the completed I/O operations.
-
-### Average Service Time (ms)
-
-The average service time for completed I/O operations. This metric is calculated using the total busy time of the disk and the number of completed operations. If the disk is able to execute multiple parallel operations the reporting average service time will be misleading.
-
-### Merged I/O operations/s
-
-The Linux kernel is capable of merging I/O operations. So, if two requests to read data from the disk are adjacent, the Linux kernel may merge them to one before giving them to disk. This metric measures the number of operations that have been merged by the Linux kernel.
-
-### Total I/O time
-
-The sum of the duration of all completed I/O operations. This number can exceed the interval if the disk is able to execute multiple I/O operations in parallel.
-
-### Space usage
-
-For mounted disks, netdata will provide a chart for their space, with 3 dimensions:
-
-1. free
-2. used
-3. reserved for root
-
-### inode usage

+## Monitoring CPUs
+
+The `/proc/stat` module monitors CPU utilization, interrupts, context switches, processes started/running, thermal throttling, frequency, and idle states. It gathers this information from multiple files.
+
+If more than 50 cores are present in a system then CPU thermal throttling, frequency, and idle state charts are disabled.
+
+#### configuration
+
+`keep per core files open` option in the `[plugin:proc:/proc/stat]` configuration section allows reducing the number of file operations on multiple files.
+
+### CPU frequency
+
+The module shows the current CPU frequency as set by the `cpufreq` kernel
+module.
+
+**Requirement:**
+You need to have `CONFIG_CPU_FREQ` and (optionally) `CONFIG_CPU_FREQ_STAT`
+enabled in your kernel.
+
+`cpufreq` interface provides two different ways of getting the information through `/sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq` and `/sys/devices/system/cpu/cpu*/cpufreq/stats/time_in_state` files. The latter is more accurate so it is preferred in the module. `scaling_cur_freq` represents only the current CPU frequency, and doesn't account for any state changes which happen between updates. The module switches back and forth between these two methods if governor is changed.
+
+It produces one chart with multiple lines (one line per core).
+
+#### configuration
+
+`scaling_cur_freq filename to monitor` and `time_in_state filename to monitor` in the `[plugin:proc:/proc/stat]` configuration section
+
+### CPU idle states
+
+The module monitors the usage of CPU idle states.
+
+**Requirement:**
+Your kernel needs to have `CONFIG_CPU_IDLE` enabled.
+
+It produces one stacked chart per CPU, showing the percentage of time spent in
+each state.
+
+#### configuration
+
+`schedstat filename to monitor`, `cpuidle name filename to monitor`, and `cpuidle time filename to monitor` in the `[plugin:proc:/proc/stat]` configuration section

+SYNPROXY is a TCP SYN packets proxy. It can be used to protect any TCP server (like a web server) from SYN floods and similar DDos attacks.
+
+SYNPROXY is a netfilter module, in the Linux kernel (since version 3.12). It is optimized to handle millions of packets per second utilizing all CPUs available without any concurrency locking between the connections.
+
+The net effect of this, is that the real servers will not notice any change during the attack. The valid TCP connections will pass through and served, while the attack will be stopped at the firewall.
+
+To use SYNPROXY on your firewall, please follow our setup guides:
+
+ - **[Working with SYNPROXY](https://github.com/firehol/firehol/wiki/Working-with-SYNPROXY)**
+ - **[Working with SYNPROXY and traps](https://github.com/firehol/firehol/wiki/Working-with-SYNPROXY-and-traps)**
+
+### Real-time monitoring of Linux Anti-DDoS
+
+netdata is able to monitor in real-time (per second updates) the operation of the Linux Anti-DDoS protection.
+
+It visualizes 4 charts:
+
+1. TCP SYN Packets received on ports operated by SYNPROXY
+2. TCP Cookies (valid, invalid, retransmits)
+3. Connections Reopened
+4. Entries used

+## Pull Request Checklist for Python Plugins
+
+This is a generic checklist for submitting a new Python plugin for Netdata. It is by no means comprehensive.
+
+At minimum, to be buildable and testable, the PR needs to include:
+
+* The module itself, following proper naming conventions: `python.d/<module_dir>/<module_name>.chart.py`
+* A README.md file for the plugin under `python.d/<module_dir>`.
+* The configuration file for the module: `conf.d/python.d/<module_name>.conf`. Python config files are in YAML format, and should include comments describing what options are present. The instructions are also needed in the configuration section of the README.md
+* A basic configuration for the plugin in the appropriate global config file: `conf.d/python.d.conf`, which is also in YAML format. Either add a line that reads `# <module_name>: yes` if the module is to be enabled by default, or one that reads `<module_name>: no` if it is to be disabled by default.
+* A line for the plugin in `python.d/Makefile.am` under `dist_python_DATA`.
+* A line for the plugin configuration file in `conf.d/Makefile.am`, under `dist_pythonconfig_DATA`
+* Optionally, chart information in `web/dashboard_info.js`. This generally involves specifying a name and icon for the section, and may include descriptions for the section or individual charts.

+# nvidia_smi
+
+This module monitors the `nvidia-smi` cli tool.
+
+**Requirements and Notes:**
+
+ * You must have the `nvidia-smi` tool installed and your NVIDIA GPU(s) must support the tool. Mostly the newer high end models used for AI / ML and Crypto or Pro range, read more about [nvidia_smi](https://developer.nvidia.com/nvidia-system-management-interface).
+
+ * You must enable this plugin as its disabled by default due to minor performance issues.
+
+ * On some systems when the GPU is idle the `nvidia-smi` tool unloads and there is added latency again when it is next queried. If you are running GPUs under constant workload this isn't likely to be an issue.
+
+ * Currently the `nvidia-smi` tool is being queried via cli. Updating the plugin to use the nvidia c/c++ API directly should resolve this issue. See discussion here: https://github.com/netdata/netdata/pull/4357
+
+ * Contributions are welcome.
+
+ * Make sure `netdata` user can execute `/usr/bin/nvidia-smi` or wherever your binary is.
+
+ * `poll_seconds` is how often in seconds the tool is polled for as an integer.
+
+It produces:
+
+1. Per GPU
+ * GPU utilization
+ * memory allocation
+ * memory utilization
+ * fan speed
+ * power usage
+ * temperature
+ * clock speed
+ * PCI bandwidth
+
+### configuration

+# openldap
+
+This module provides statistics information from openldap (slapd) server.
+Statistics are taken from LDAP monitoring interface. Manual page, slapd-monitor(5) is available.
+
+**Requirement:**
+* Follow instructions from https://www.openldap.org/doc/admin24/monitoringslapd.html to activate monitoring interface.
+* Install python ldap module `pip install ldap` or `yum install python-ldap`
+* Modify openldap.conf with your credentials
+
+### Module gives information with following charts:
+
+1. **connections**
+ * total connections number
+
+2. **Bytes**
+ * sent
+
+3. **operations**
+ * completed
+ * initiated
+
+4. **referrals**
+ * sent
+
+5. **entries**
+ * sent
+
+6. **ldap operations**
+ * bind
+ * search
+ * unbind
+ * add
+ * delete
+ * modify
+ * compare
+
+7. **waiters**
+ * read
+ * write
+
+
+
+### configuration
+
+Sample:
+
+```yaml
+openldap:
+ name : 'local'
+ username : "cn=monitor,dc=superb,dc=eu"
+ password : "testpass"
+ server : 'localhost'
+ port : 389
+```

+`smartd` must be running with `-A` option to write smartd attribute information to files.
+
+For this you need to set `smartd_opts` (or `SMARTD_ARGS`, check _smartd.service_ content) in `/etc/default/smartmontools`:
+
+
+```
+# dump smartd attrs info every 600 seconds
+smartd_opts="-A /var/log/smartd/ -i 600"
+```
+
+
+`smartd` appends logs at every run. It's strongly recommended to use `logrotate` for smartd files.

+
The Spring Boot Actuator exposes these metrics over HTTP and is very easy to use:
* add `org.springframework.boot:spring-boot-starter-actuator` to your application dependencies
* set `endpoints.metrics.sensitive=false` in your `application.properties`

+Module connects to tor control port to collect traffic statistics.
+
+**Requirements:**
+* `tor` program
+* `stem` python package
+
+It produces only one chart:
+
+1. **Traffic**
+ * read
+ * write
+
+### configuration
+
+Needs only `control_port`
+
+Here is an example for local server:
+
+```yaml
+update_every : 1
+priority : 60000
+
+local_tcp:
+ name: 'local'
+ control_port: 9051
+
+local_socket:
+ name: 'local'
+ control_port: '/var/run/tor/control'
+```
+
+### prerequisite
+
+Add to `/etc/tor/torrc`:
+
+```
+ControlPort 9051
+```
+
+For more options please read the manual.
+
+Without configuration, module attempts to connect to `127.0.0.1:9051`.

# web_log
-Tails the apache/nginx/lighttpd/gunicorn log files to collect real-time web-server statistics.
+## Motivation
-It produces following charts:
+Web server log files exist for more than 20 years. All web servers of all kinds, from all vendors, [since the time NCSA httpd was powering the web](https://en.wikipedia.org/wiki/NCSA_HTTPd), produce log files, saving in real-time all accesses to web sites and APIs.
-1. **Response by type** requests/s
+Yet, after the appearance of google analytics and similar services, and the recent rise of APM (Application Performance Monitoring) with sophisticated time-series databases that collect and analyze metrics at the application level, all these web server log files are mostly just filling our disks, rotated every night without any use whatsoever.
+
+netdata turns this "useless" log file, into a powerful performance and health monitoring tool, capable of detecting, **in real-time**, most common web server problems, such as:
+
+- too many redirects (i.e. **oops!** *this should not redirect clients to itself*)
+- too many bad requests (i.e. **oops!** *a few files were not uploaded*)
+- too many internal server errors (i.e. **oops!** *this release crashes too much*)
+- unreasonably too many requests (i.e. **oops!** *we are under attack*)
+- unreasonably few requests (i.e. **oops!** *call the network guys*)
+- unreasonably slow responses (i.e. **oops!** *the database is slow again*)
+- too few successful responses (i.e. **oops!** *help us God!*)
+
+## Usage
+
+If netdata is installed on a system running a web server, it will detect it and it will automatically present a series of charts, with information obtained from the web server API, like these (*these do not come from the web server log file*):
+
+![image](https://cloud.githubusercontent.com/assets/2662304/22900686/e283f636-f237-11e6-93d2-cbdf63de150c.png)
+*[**netdata**](https://my-netdata.io/) charts based on metrics collected by querying the `nginx` API (i.e. `/stab_status`).*
+
+> [**netdata**](https://my-netdata.io/) supports `apache`, `nginx`, `lighttpd` and `tomcat`. To obtain real-time information from a web server API, the web server needs to expose it. For directions on configuring your web server, check the config files for each web server. There is a directory with a config file for each web server under [`/etc/netdata/python.d/`](../).
+
+## Configuration
+
+[**netdata**](https://my-netdata.io/) has a powerful `web_log` plugin, capable of incrementally parsing any number of web server log files. This plugin is automatically started with [**netdata**](https://my-netdata.io/) and comes, pre-configured, for finding web server log files on popular distributions. Its configuration is at [`/etc/netdata/python.d/web_log.conf`](web_log.conf), like this:
+
+
+```yaml
+nginx_log:
+ name : 'nginx_log'
+ path : '/var/log/nginx/access.log'
+
+apache_log:
+ name : 'apache_log'
+ path : '/var/log/apache/other_vhosts_access.log'
+ categories:
+ cacti : 'cacti.*'
+ observium : 'observium'
+```
+
+Theodule has preconfigured jobs for nginx, apache and gunicorn on various distros.
+You can add one such section, for each of your web server log files.
+
+> **Important**<br/>Keep in mind [**netdata**](https://my-netdata.io/) runs as user `netdata`. So, make sure user `netdata` has access to the logs directory and can read the log file.
+
+## Charts
+
+Once you have all log files configured and [**netdata**](https://my-netdata.io/) restarted, **for each log file** you will get a section at the [**netdata**](https://my-netdata.io/) dashboard, with the following charts.
+
+### responses by status
+
+In this chart we tried to provide a meaningful status for all responses. So:
+
+- `success` counts all the valid responses (i.e. `1xx` informational, `2xx` successful and `304` not modified).
+- `error` are `5xx` internal server errors. These are very bad, they mean your web site or API is facing difficulties.
+- `redirect` are `3xx` responses, except `304`. All `3xx` are redirects, but `304` means "not modified" - it tells the browsers the content they already have is still valid and can be used as-is. So, we decided to account it as a successful response.
+- `bad` are bad requests that cannot be served.
+- `other` as all the other, non-standard, types of responses.

-4. **Bandwidth** KB/s
+### bandwidth
+
+This is a nice view of the traffic the web server is receiving and is sending.
+
+What is important to know for this chart, is that the bandwidth used for each request and response is accounted at the time the log is written. Since [**netdata**](https://my-netdata.io/) refreshes this chart every single second, you may have unrealistic spikes is the size of the requests or responses is too big. The reason is simple: a response may have needed 1 minute to be completed, but all the bandwidth used during that minute for the specific response will be accounted at the second the log line is written.
+
+As the legend on the chart suggests, you can use FireQoS to setup QoS on the web server ports and IPs to accurately measure the bandwidth the web server is using. Actually, [there may be a few more reasons to install QoS on your servers](../../tc.plugin/#tcplugin)...
+
+**Bandwidth** KB/s
* received (bandwidth of requests)

+
+> **Important**<br/>Most web servers do not log the request size by default.<br/>So, [unless you have configured your web server to log the size of requests](https://github.com/netdata/netdata/blob/419cd0a237275e5eeef3f92dcded84e735ee6c58/conf.d/python.d/web_log.conf#L76-L89), the `received` dimension will be always zero.
-5. **Timings** ms (request processing time)
+### timings
+
+[**netdata**](https://my-netdata.io/) will also render the `minimum`, `average` and `maximum` time the web server needed to respond to requests.
+
+Keep in mind most web servers timings start at the reception of the full request, until the dispatch of the last byte of the response. So, they include network latencies of responses, but they do not include network latencies of requests.

-6. **Request per url** requests/s (configured by user)
+> **Important**<br/>Most web servers do not log timing information by default.<br/>So, [unless you have configured your web server to also log timings](https://github.com/netdata/netdata/blob/419cd0a237275e5eeef3f92dcded84e735ee6c58/conf.d/python.d/web_log.conf#L76-L89), this chart will not exist.
-7. **Http Methods** requests/s (requests per http method)
+### URL patterns
-8. **Http Versions** requests/s (requests per http version)
+This is a very interesting chart. It is configured entirely by you.
-9. **IP protocols** requests/s (requests per ip protocol version)
+[**netdata**](https://my-netdata.io/) can map the URLs found in the log file into categories. You can define these categories, by providing names and regular expressions in `web_log.conf`.
-10. **Current Poll Unique Client IPs** unique ips/s (unique client IPs per data collection iteration)
+So, this configuration:
-11. **All Time Unique Client IPs** unique ips/s (unique client IPs since the last restart of netdata)
+```yaml
+nginx_netdata: # name the charts
+ path: '/var/log/nginx/access.log' # web server log file

+
+### Unique clients
+
+The last charts are about the unique IPs accessing your web server.

+
+>**Important**<br/>To provide this information `web_log` plugin keeps in memory all the IPs seen by the web server. Although this does not require so much memory, if you have a web server with several million unique client IPs, we suggest to [disable this chart](https://github.com/netdata/netdata/blob/419cd0a237275e5eeef3f92dcded84e735ee6c58/conf.d/python.d/web_log.conf#L64).

+
+## Alarms
+
+The magic of [**netdata**](https://my-netdata.io/) is that all metrics are collected per second, and all metrics can be used or correlated to provide real-time alarms. Out of the box, [**netdata**](https://my-netdata.io/) automatically attaches the [following alarms](../../../health/health.d/web_log.conf) to all `web_log` charts (i.e. to all log files configured, individually):
+
+alarm|description|minimum<br/>requests|warning|critical
+:-------|-------|:------:|:-----:|:------:
+`1m_redirects`|The ratio of HTTP redirects (3xx except 304) over all the requests, during the last minute.<br/>&nbsp;<br/>*Detects if the site or the web API is suffering from too many or circular redirects.*<br/>&nbsp;<br/>(i.e. **oops!** *this should not redirect clients to itself*)|120/min|&gt; 20%|&gt; 30%
+`1m_bad_requests`|The ratio of HTTP bad requests (4xx) over all the requests, during the last minute.<br/>&nbsp;<br/>*Detects if the site or the web API is receiving too many bad requests, including `404`, not found.*<br/>&nbsp;<br/>(i.e. **oops!** *a few files were not uploaded*)|120/min|&gt; 30%|&gt; 50%
+`1m_internal_errors`|The ratio of HTTP internal server errors (5xx), over all the requests, during the last minute.<br/>&nbsp;<br/>*Detects if the site is facing difficulties to serve requests.*<br/>&nbsp;<br/>(i.e. **oops!** *this release crashes too much*)|120/min|&gt; 2%|&gt; 5%
+`5m_requests_ratio`|The percentage of successful web requests of the last 5 minutes, compared with the previous 5 minutes.<br/>&nbsp;<br/>*Detects if the site or the web API is suddenly getting too many or too few requests.*<br/>&nbsp;<br/>(i.e. too many = **oops!** *we are under attack*)<br/>(i.e. too few = **oops!** *call the network guys*)|120/5min|&gt; double or &lt; half|&gt; 4x or &lt; 1/4x
+`web_slow`|The average time to respond to requests, over the last 1 minute, compared to the average of last 10 minutes.<br/>&nbsp;<br/>*Detects if the site or the web API is suddenly a lot slower.*<br/>&nbsp;<br/>(i.e. **oops!** *the database is slow again*)|120/min|&gt; 2x|&gt; 4x
+`1m_successful`|The ratio of successful HTTP responses (1xx, 2xx, 304) over all the requests, during the last minute.<br/>&nbsp;<br/>*Detects if the site or the web API is performing within limits.*<br/>&nbsp;<br/>(i.e. **oops!** *help us God!*)|120/min|&lt; 85%|&lt; 75%
+
+The column `minimum requests` state the minimum number of requests required for the alarm to be evaluated. We found that when the site is receiving requests above this rate, these alarms are pretty accurate (i.e. no false-positives).
-Module has preconfigured jobs for nginx, apache and gunicorn on various distros.
+[**netdata**](https://my-netdata.io/) alarms are user configurable. Sample config files can be found under directory `health/health.d` of the netdata github repository. So, even [`web_log` alarms can be adapted to your needs](../../../health/health.d/web_log.conf).

+Others use NFACCT, the netfilter accounting module which is already part of the Linux firewall. However, this would require configuring a firewall on every system you want to measure bandwidth (just FYI, I do install a firewall on every server - and I strongly advise you to do so too - but configuring accounting on all servers seems overkill when you don't really need it for billing purposes).
-QoS monitoring attempts to solve this in a much cleaner way.
+**There is however a much simpler approach**.
-## Introduction to QoS
+## QoS

-**apply QoS on traffic**. Even most interesting is that it can apply QoS to **both inbound and
-outbound traffic**.
+One of the features the Linux kernel has, but it is rarely used, is its ability to **apply QoS on traffic**. Even most interesting is that it can apply QoS to **both inbound and outbound traffic**.
QoS is about 2 features:
1. **Classify traffic**
- Classification is the process of organizing traffic in groups, called **classes**.
- Classification can evaluate every aspect of network packets, like source and destination ports,
- source and destination IPs, netfilter marks, etc.
+ Classification is the process of organizing traffic in groups, called **classes**. Classification can evaluate every aspect of network packets, like source and destination ports, source and destination IPs, netfilter marks, etc.
- When you classify traffic, you just assign a label to it. For example **I call `web server`
- traffic, the traffic from my server's tcp/80, tcp/443 and to my server's tcp/80, tcp/443,
- while I call `web surfing` all other tcp/80 and tcp/443 traffic**. You can use any combinations
- you like. There is no limit.
+ When you classify traffic, you just assign a label to it. Of course classes have some properties themselves (like queuing mechanisms), but let's say it is that simple: **a label**. For example **I call `web server` traffic, the traffic from my server's tcp/80, tcp/443 and to my server's tcp/80, tcp/443, while I call `web surfing` all other tcp/80 and tcp/443 traffic**. You can use any combinations you like. There is no limit.
2. **Apply traffic shaping rules to these classes**
- Traffic shaping is used to control how network interface bandwidth should be shared among the
- classes. Of course we are not interested for this feature to just monitor the traffic.
- Classification will be enough for monitoring everything.
+ Traffic shaping is used to control how network interface bandwidth should be shared among the classes. Normally, you need to do this, when there is not enough bandwidth to satisfy all the demand, or when you want to control the supply of bandwidth to certain services. Of course classification is sufficient for monitoring traffic, but traffic shaping is also quite important, as we will explain in the next section.
-The key reasons of applying QoS on all servers (even cloud ones) are:
+## Why you want QoS
- - **ensure administrative tasks (like ssh, dns, etc) will always have a small but guaranteed
- bandwidth.** QoS can guarantee that services like ssh, dns, ntp, etc will always have a small
- supply of bandwidth. So, no matter what happens, you will be able to ssh to your server and
- DNS will always work.
+1. **Monitoring the bandwidth used by services**
- - **ensure other administrative tasks will not monopolize all the available bandwidth.**
- Services like backups, file copies, database dumps, etc can easily monopolize all the
- available bandwidth. It is common for example a nightly backup, or a huge file transfer
- to negatively influence the end-user experience. QoS can fix that.
+ netdata provides wonderful real-time charts, like this one (wait to see the orange `rsync` part):
- - **ensure each end-user connection will get a fair cut of the available bandwidth.**
- Several QoS queuing disciplines in Linux do this automatically, without any configuration from you.
- The result is that new sockets are favored over older ones, so that users will get a snappier
- experience, while others are transferring large amounts of traffic.
-

+2. **Ensure sensitive administrative tasks will not starve for bandwidth**
-Once **traffic classification** is applied, netdata can visualize the bandwidth consumption per
-class in real-time (no configuration is needed for netdata - it will figure it out).
+ Have you tried to ssh to a server when the network is congested? If you have, you already know it does not work very well. QoS can guarantee that services like ssh, dns, ntp, etc will always have a small supply of bandwidth. So, no matter what happens, you will be able to ssh to your server and DNS will always work.
-QoS, is extremely light. You will configure it once, and this is it. It will not bother you again
-and it will not use any noticeable CPU resources, especially on application and database servers.
+3. **Ensure administrative tasks will not monopolize all the bandwidth**
+
+ Services like backups, file copies, database dumps, etc can easily monopolize all the available bandwidth. It is common for example a nightly backup, or a huge file transfer to negatively influence the end-user experience. QoS can fix that.
+
+4. **Ensure each end-user connection will get a fair cut of the available bandwidth.**
+
+ Several QoS queuing disciplines in Linux do this automatically, without any configuration from you. The result is that new sockets are favored over older ones, so that users will get a snappier experience, while others are transferring large amounts of traffic.
+
+5. **Protect the servers from DDoS attacks.**
+
+ When your system is under a DDoS attack, it will get a lot more bandwidth compared to the one it can handle and probably your applications will crash. Setting a limit on the inbound traffic using QoS, will protect your servers (throttle the requests) and depending on the size of the attack may allow your legitimate users to access the server, while the attack is taking place.
+
+ Using QoS together with a [SYNPROXY](../proc.plugin/README.md#linux-anti-ddos) will provide a great degree of protection against most DDoS attacks. Actually when I wrote that article, a few folks tried to DDoS the netdata demo site to see in real-time the SYNPROXY operation. They did not do it right, but anyway a great deal of requests reached the netdata server. What saved netdata was QoS. The netdata demo server has QoS installed, so the requests were throttled and the server did not even reach the point of resource starvation. Read about it [here](../proc.plugin/README.md#linux-anti-ddos).
+
+On top of all these, QoS is extremely light. You will configure it once, and this is it. It will not bother you again and it will not use any noticeable CPU resources, especially on application and database servers.
+
+ - ensure administrative tasks (like ssh, dns, etc) will always have a small but guaranteed bandwidth. So, no matter what happens, I will be able to ssh to my server and DNS will work.
+
+ - ensure other administrative tasks will not monopolize all the available bandwidth. So, my nightly backup will not hurt my users, a developer that is copying files over the net will not get all the available bandwidth, etc.
+
+ - ensure each end-user connection will get a fair cut of the available bandwidth.
+
+Once **traffic classification** is applied, we can use **[netdata](https://github.com/netdata/netdata)** to visualize the bandwidth consumption per class in real-time (no configuration is needed for netdata - it will figure it out).
