Icinga 2 provides configuration files for some commonly used features.
These are installed in the /etc/icinga2/features-available directory and can be enabled and disabled using the icinga2 feature enable and icinga2 feature disable CLI commands, respectively.
The icinga2 feature enable CLI command creates symlinks in the /etc/icinga2/features-enabled directory which is included by default in the example configuration file.
You can view a list of enabled and disabled features:
# icinga2 feature list Disabled features: api command compatlog debuglog graphite icingastatus ido-mysql ido-pgsql livestatus notification perfdata statusdata syslog Enabled features: checker mainlog notification
Using the icinga2 feature enable command you can enable features:
# icinga2 feature enable graphite Enabling feature graphite. Make sure to restart Icinga 2 for these changes to take effect.
You can disable features using the icinga2 feature disable command:
# icinga2 feature disable ido-mysql livestatus Disabling feature ido-mysql. Make sure to restart Icinga 2 for these changes to take effect. Disabling feature livestatus. Make sure to restart Icinga 2 for these changes to take effect.
The icinga2 feature enable and icinga2 feature disable commands do not restart Icinga 2. You will need to restart Icinga 2 using the init script after enabling or disabling features.
