== Load external configuration files
|
||
|
|
|
||
|
|
Metricbeat can load external configuration files for modules, which allows you
|
||
|
|
to separate your configuration into multiple smaller configuration files. To use
|
||
|
|
this, you specify the `path` option under `metricbeat.config.modules` in the
|
||
|
|
main `metricbeat.yml` configuration file. By default, Metricbeat loads the
|
||
|
|
module configurations enabled in the <<enable-modules-d-configs,`modules.d`>>
|
||
|
|
directory. For example:
|
||
|
|
|
||
|
|
[source,yaml]
|
||
|
|
------------------------------------------------------------------------------
|
||
|
|
metricbeat.config.modules:
|
||
|
|
path: ${path.config}/modules.d/*.yml
|
||
|
|
------------------------------------------------------------------------------
|
||
|
|
|
||
|
|
|
||
|
|
`path`:: A Glob that defines the files to check for changes.
|
||
|
|
+
|
||
|
|
This setting must point to the `modules.d` directory if you want to use the
|
||
|
|
<<modules-command,`modules`>> command to enable and disable module
|
||
|
|
configurations.
|
||
|
|
|
||
|
|
Each file found by the Glob must contain a list of one or more module
|
||
|
|
definitions. For example:
|
||
|
|
|
||
|
|
[source,yaml]
|
||
|
|
------------------------------------------------------------------------------
|
||
|
|
- module: system
|
||
|
|
metricsets: ["cpu"]
|
||
|
|
enabled: false
|
||
|
|
period: 1s
|
||
|
|
|
||
|
|
- module: system
|
||
|
|
metricsets: ["network"]
|
||
|
|
enabled: true
|
||
|
|
period: 10s
|
||
|
|

=== Live reloading
|
||
|
|
|
||
|
|
You can configure Metricbeat to dynamically reload configuration files when
|
||
|
|
there are changes. To do this, you specify a path
|
||
|
|
(https://golang.org/pkg/path/filepath/#Glob[Glob]) to watch for module
|
||
|
|
configuration changes. When the files found by the Glob change, new modules are
|
||
|
|
started/stopped according to changes in the configuration files.
|
||
|
|
|
||
|
|
This feature is especially useful in container environments where one container
|
||
|
|
is used to monitor all services running in other containers on the same host.
|
||
|
|
Because new containers appear and disappear dynamically, you may need to change
|
||
|
|
the Metricbeat configuration frequently to specify which modules are needed and
|
||
|
|
which hosts must be monitored.
|
||
|
|
|
||
|
|
To enable dynamic config reloading, you specify the `path` and `reload` options
|
||
|
|
under `metricbeat.config.modules` in the main `metricbeat.yml` config file. For
|
||
|
|
example:
|
||
|
|
|
||
|
|
[source,yaml]
|
||
|
|
------------------------------------------------------------------------------
|
||
|
|
metricbeat.config.modules:
|
||
|
|
path: ${path.config}/modules.d/*.yml
|
||
|
|
reload.enabled: true
|
||
|
|
reload.period: 10s
|
||
|
|
------------------------------------------------------------------------------
|

|
|
||
|
|
`path`:: A Glob that defines the files to check for changes.
|
||
|
|
+
|
||
|
|
This setting must point to the `modules.d` directory if you want to use the
|
||
|
|
<<modules-command,`modules`>> command to enable and disable module
|
||
|
|
configurations.
|
||
|
|
|
||
|
|
`reload.enabled`:: When set to `true`, enables dynamic config reload.
|
||
|
|
|
||
|
|
`reload.period`:: Specifies how often the files are checked for changes. Do not
|
||
|
|
set the `period` to less than 1s because the modification time of files is often
|
||
|
|
stored in seconds. Setting the `period` to less than 1s will result in
|
||
|
|
unnecessary overhead.
