Linux physical memory critical - agent based polling, memory is "available"

wes.reneau over 2 years ago

I know this has been discussed on numerous threads and short of missing something in those threads, I'm still left w/ a question.

1. using agent-based polling

2. not monitoring buffers, cached or shared memory

I know about this:
Help! Linux ate my RAM!

The node is monitored via the agent. I'm dealing w/ an onslaught of critical alerts repeatedly. The nodes are fine but the NOC team is obliged to respond to each.

Many of my vm's are reporting critical physical memory consumption, but in reality, they are fine.

I have the following monitored

This is what memory shows me on the server itself

Ideas?

I typically find little use for monitoring the memory volumes. I may be off base in that practice, but I have always used the SAM template to get a better idea of the memory utilization on a Linux server…

wes.reneau, Do you have Server and Application Monitor (SAM)? If so, have you considered applying the Linux Memory Monitoring Perl Template and seeing if that is a more meaningful method or metric to have your NOC respond to?

I'm curious about this one, too. Would you recommend un-checking the memory "volumes" in the Resource List on Linux nodes after switching to the SAM monitoring template?
