Looks good, but no performance data, which I would like to be able to
trend memory usage and justify upgrades. Anyone familiar with a good
memory test that properly handles memory reservations AND also includes
performance trending data?

So along with disk and CPU tests, I want to test for memory usage. I
pulled a perl memory script off Nagios Exchange and was quickly
reminded of how linux handles memory... how it leaves whatever has
been used previously as "reserved". Thus, a server with 4Gb of RAM
may show that 3.95Gb is in use, but in reality, more like 512Mb is in
use and the swap usage is under 10%, if used at all, confirming the
"actual versus reserved" issue. So how are you guys testing for
memory on Linux boxes that flag it as reserved when its not? Are
there any scripts on Nagios Exchange for memory testing that are
better than others?
I use check_memory.pl. It properly takes buffers and cache into
consideration (using the "free" command).
