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?
