Hi guys,
We are having problem with nagios monitoring memory usage on one of our nodes.
On the node :total used free shared buff/cache available
Mem: 2848 178 1902 8 767 2506
Swap: 2047 0 2047
While the service monitoring in nagios is:
CRITICAL - 5168 / 2848 MB (%) Free Memory, Used: 182 MB, Shared: 8 MB, Buffers: 764 MB, Cached: 2502 MB
Pls can anyone offer an help?

Can you post which plugin you are using and how the check is configured in XI?

We are using the regular linux server wizard and the default memory usage plugging that comes with it.
Other services monitor ok, except the memory usage metric.
Thanks!

if this is an RHEL/Centos 6 or 7 box you might check if slab is using memory...
grep -i reclaim /proc/meminfo

What Operating System is the remote machine running and what version is it?
Can you please post how the check is configured in XI.

It's Linux rhel7....
Here is how the check is being configured; check_nrpe!check_mem!-a '-w 20 -c 10'!!!!!!
We used the default memory usage metric.
Thanks!

The updated plugin in that post *should* fix your issue.
