External Commands
Damit Kommandos über das Webinterface ausgeführt werden dürfen sind einige Schritte erforderlich. Diese sind in /usr/share/doc/icinga/README.Debian auch beschrieben.
Zuerst wird die Option check_external_commands in der Konfigurationsdatei /etc/icinga/icinga.cfg auf 1 gesetzt:
# EXTERNAL COMMAND OPTION # This option allows you to specify whether or not Icinga should check # for external commands (in the command file defined below). By default # Icinga will *not* check for external commands, just to be on the # cautious side. If you want to be able to use the CGI command interface # you will have to enable this. # Values: 0 = disable commands, 1 = enable commands check_external_commands=1
Danach müssen noch die Dateiberechtigungen angepasst werden:
sudo /etc/init.d/icinga stop sudo dpkg-statoverride --update --add nagios www-data 2710 /var/lib/icinga/rw sudo dpkg-statoverride --update --add nagios nagios 751 /var/lib/icinga sudo /etc/init.d/icinga start
