Check_ram

As some people know, I previously " created" (mostly modified the check_swap plug-in to print RAM usage) check_ram in C. Now one of my problems for the past few months was putting the C plug-in as well as " supported" environment under the same hat. Today I had another look at the amount of available plug-ins in NagiosExchange. There are quite a few plug-ins available, but as I do have some experience with Python, I used the one written in Python. It was rather easy hacking in support for performance data into it, as the below shows. Someone else already posted a non-unified diff for performance data support, but that ain’t quite right according to the Nagios plug-in development guidelines.

As I was building the updated RPMs for SLES10, though needed to refresh my old patch. Also, I was getting strange messages from autotools and fixed these quirks, Now, I prepped a patch for it, and finished building new RPMs for i586 and x86_64.

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! ...
