Nagios/Icinga can also serve to send you friendly reminders, like for example that you need to perform software updates.
Here’s my little contribution, a simple plugin to monitor a given DokuWiki site and check against the release server for any upgrades.
Just fetch the check_dokuwiki-0.1 check_dokuwiki-0.2 tarball and extract the check_dokuwiki script to your Nagios/Icinga plugin directory.
The latest plugin update (0.2, 2015-09-06) catches up with latest updates on Dokuwikis web page, and now incorporates upstream checks using the same mechanism that Dokuwiki uses internally. Also it adds some (although not yet well tested) support for http authentication.
Please check out the cli help for more details on specific arguments:
check_dokuwiki v (nagios-plugins 1.4.15)

}
Then simply add a service to one or more of your DokuWiki hosts (or hostgroups, whatever you prefer).
define service{
use generic-service
host_name your_wiki_host_objects_list_here
service_description dokuwiki_version
check_command check_dokuwiki
max_check_attempts 5
check_interval 5
retry_interval 3

Restart Nagios/Icinga and you’re done.
Happy monitoring 🙂
