The daemon configuration file is read from
Depending on your installation method, Netdata will have been installed either directly under
/, or under
/opt/netdata. The paths mentioned here and in the documentation in general assume that your installation is under
/. If it is not, you will find the exact same paths under
/opt/netdata as well. (i.e.
/etc/netdata will be
This config file is not needed by default. Netdata works fine out of the box without it. But it does allow you to adapt the general behavior of Netdata, in great detail. You can find all these settings, with their default values, by accessing the URL
https://netdata.server.hostname:19999/netdata.conf. For example check the configuration file of netdata.firehol.org. HTTP access to this file is limited by default to private IPs, via the web server access lists.
netdata.conf has sections stated with
[section]. You will see the following sections:
[global]to configure the netdata daemon.
[web]to configure the web server.
[plugins]to configure which collectors to use and PATH settings.
[health]to configure general settings for health monitoring
[registry]for the netdata registry.
[backend]to set up streaming and replication options.
[statsd]for the general settings of the stats.d.plugin.
[plugin:NAME]sections for each collector plugin, under the comment Per plugin configuration.
[CHART_NAME]sections for each chart defined, under the comment Per chart configuration.
The configuration file is a
name = value dictionary. Netdata will not complain if you set options unknown to it. When you check the running configuration by accessing the URL
/netdata.conf on your netdata server, netdata will add a comment on settings it does not currently use.
netdata.conf has been modified, netdata needs to be restarted for changes to apply:
sudo service netdata restart
If the above does not work, try the following:
sudo killall netdata; sleep 10; sudo netdata

[web] section options¶
Refer to the web server documentation
[plugins] section options¶
In this section you will see be a boolean (
no) option for each plugin (e.g. tc, cgroups, apps, proc etc.). Note that the configuration options in this section for the orchestrator plugins
node.d control all the modules written for that orchestrator. For instance, setting
python.d = no means that all Python modules under
collectors/python.d.plugin will be disabled.
Additionally, there will be the following options:
|PATH environment variable||
|PYTHONPATH environment variable||Used to set a custom python path|
|enable running new plugins||
||When set to

[health] section options¶
This section controls the general behavior of the health monitoring capabilities of Netdata.
Specific alarms are configured in per-collector config files under the
health.d directory. For more info, see health monitoring.
Alarm notifications are configured in
|in memory max health log entries||1000||Size of the alarm history held in RAM|

[registry] section options¶
To understand what this section is and how it should be configured, please refer to the registry documentation.
Refer to the streaming and replication documentation.
Per plugin configuration¶
The configuration options for plugins appear in sections following the pattern
Most internal plugins will provide additional options. Check Internal Plugins for more information.
Please note, that by default Netdata will enable monitoring metrics for disks, memory, and network only when they are not zero. If they are constantly zero they are ignored. Metrics that will start having values, after netdata is started, will be detected and charts will be automatically added to the dashboard (a refresh of the dashboard is needed for them to appear though). Use
yes instead of
auto in plugin configuration sections to enable these charts permanently. You can also set the
enable zero metrics option to
yes in the
[global] section which enables charts with zero metrics for all internal Netdata plugins.
External plugins will have only 2 options at
|update every||the value of
||The frequency in seconds the plugin should collect values. For more information check Performance.|
|command options||empty||Additional command line options to pass to the plugin.|
External plugins that need additional configuration may support a dedicated file in
/etc/netdata. Check their documentation.
Per chart configuration¶
In this section you will find a separate subsection for each chart shown on the dashboard. You can control all aspects of a specific chart here. You can understand what each option does by reading how charts are defined. If you don’t know how to find the name of a chart, you can learn about it here.
