Nagios

Well, it turns out that my thought was ultimativly flawed. When defining the hostgroup_members in the lower tiers, nagios is association the checks from the lower tier with the upper tiers. Thus propagandating all checks upwards, and me ending up with ~250 checks instead of ~150. Gonna have to try to define the dependency backwards, maybe that’ll help. But that’s a topic for Monday. Guess I’ll finish viewing Ghost in the Shell - Stand Alone Complex first.

Well, it seems to be getting a “trend” for me, to integrate stuff into our Active Directory. Now that I know why, and how easy that is, I expect to add more stuff. The good thing about the integration is, that you only need to maintain a single source for authorization. The bad thing about that is, that stuff becomes dependent on the Active Directory (we do have four domain controllers, so that should be fine). ...

Since we started utilizing Nagios’s power two months ago, I finally came up with a C-based ram-plugin for nagios. The biggest problem I had with the python and perl based plugins, that some distributions (yes, SLES and Debian) don’t install either Python or Perl. Since I wanted a manageable setup (as in unified code base across all distributions), I wanted it to work without installing too much. So I took the swap plugin and basically removed what wasn’t necessary and voila! ...
