External Commands

Icinga 2 provides an external command pipe for processing commands triggering specific actions (for example rescheduling a service check through the web interface).

In order to enable the ExternalCommandListener configuration use the following command and restart Icinga 2 afterwards:

# icinga2-enable-feature command

Icinga 2 creates the command pipe file as /var/run/icinga2/cmd/icinga2.cmd using the default configuration.

Web interfaces and other Icinga addons are able to send commands to Icinga 2 through the external command pipe, for example for rescheduling a forced service check:

# /bin/echo "[`date +%s`] SCHEDULE_FORCED_SVC_CHECK;localhost;ping4;`date +%s`" >> /var/run/icinga2/cmd/icinga2.cmd

# tail -f /var/log/messages

Oct 17 15:01:25 icinga-server icinga2: Executing external command: [1382014885] SCHEDULE_FORCED_SVC_CHECK;localhost;ping4;1382014885
Oct 17 15:01:25 icinga-server icinga2: Rescheduling next check for service 'ping4'

Note

The command pipe file is owned by the group icingacmd with read/write permissions. Add your webserver's user to the group icingacmd to enable sending commands to Icinga 2 through your web interface.

# usermod -G -a icingacmd www-data
