[id="{beatname_lc}-configuration-reloading"]
== Reload the configuration dynamically

beta[]

You can configure {beatname_uc} 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.

To enable dynamic config reloading, you specify the `path` and `reload` options
in the main +{beatname_lc}.yml+ config file. For example:

["source","sh"]
------------------------------------------------------------------------------
auditbeat.config.modules:
  path: ${path.config}/conf.d/*.yml
  reload.enabled: true
  reload.period: 10s
------------------------------------------------------------------------------

*`path`*:: A glob that defines the files to check for changes.

*`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.

Each file found by the glob must contain a list of one or more module
definitions. For example:

[source,yaml]
------------------------------------------------------------------------------
- module: file_integrity
  paths:
  - /www/wordpress
  - /www/wordpress/wp-admin
  - /www/wordpress/wp-content
  - /www/wordpress/wp-includes
------------------------------------------------------------------------------

NOTE: On systems with POSIX file permissions, all Beats configuration files are
subject to ownership and file permission checks. If you encounter config loading
errors related to file ownership, see {libbeat}/config-file-permissions.html.
