A utility called icingastats is included in the Icinga distribution. It is compiled and installed along with the main Icinga daemon. The icingastats utility allows you to obtain various information about a running Icinga process that can be very helpful in tuning performance. You can obtain information either in human-readable or performance data compatible format.

You can run the icingastats utility with the --help option to get usage information.

To obtain human-readable information on the performance of a running Icinga process, run the icingastats utility with the -c command line argument to specify your main configuration file location like such:

[icinga@monitoring ~]# /usr/local/icinga/bin/icingastats -c /usr/local/icinga/etc/icinga.cfg

[icinga@monitoring ~]#

As you can see, the utility displays a number of different metrics pertaining to the Icinga process. Metrics which have multiple values are (unless otherwise specified) min, max and average values for that particular metric.

You can use the icingastats utility to display various Icinga metrics using PNP4Nagios (or other compatible programmes). To do so, run the icingastats utility using the --mrtg and --data arguments. The --data argument is used to specify what statistics should be graphed. Possible values for the --data argument can be found by running the icingastats utility with the --help option.
