TODO: Ole Ernst – Write Installation Details DokuIcinga will be automatically installed and setup when installing icingaweb2-module-director, which is a dependency of nmsprime-hfcreq.
Issue: Icinga won't start after hostname change
Icinga stores the old hostname in a cache file, thus having problems to restart if the hostname was changed. The solutions is as follows:
- rm /var/cache/icinga2/icinga2.{debug,vars}
- icinga2 api setup
- systemctl restart icinga2.service
