Plugin to get info from /proc/meminfo. This plugin lets you get any info from meminfo, including anything that may be architecture specific or added in the future.

As well as getting performance data, you can also set warning and critical thresholds that can trigger notifications, etc, in Nagios.

The benefit of this plugin over other meminfo scraping scripts is that it generic and does not try to interpret the data in any way.

I wrote this because I wished to monitor an NFS performance issue we had and I wanted to get performance data for Cached,Buffers,Dirty,Writeback and NFS_Unstable. I then created a Nagios NFS/Disk Cache stats service in Nagios and used pnp4nagios for graphing the performance data. Now we can tune our NFS performance and see the effect of the changes via the graphs.
