Maximum amount of memory used by Nagios XI

This is probably what's going on: https://www.linuxatemyram.com/

What's the output of free -m?

You may just need to use a different check, or adjust your thresholds.

Code: Select all

# free -m
             total       used       free     shared    buffers     cached
Mem:         19983       8829      11153         15        163       1141
-/+ buffers/cache:       7524      12458
Swap:          255          0        255

Definitely looks like 16GB would do it. You could go with 12GB, it looks like.

Did you have any other questions, or does the output of free -m resolve the issue for you?

[tmattingly]

I do agree with you. Again, I'm trying to keep the usage of memory under 90% so how do I limit it if I have a 16gb of ram to limit to say 14GB? This is so my other alert tools won't fire off with excessive memory consumption?

You just need to use a different plugin. This one should suffice: https://exchange.nagios.org//directory/ ... sh/details

Good point but my other software is Spotlight by Quest. Hence the reason I'm trying to leave some buffer so it won't alarm. see attachment

I'm not familiar with spotlight, but are there other options available for it to monitor a system or system memory? The problem comes down to it's checking a value that, while technically correct, doesn't give a real good idea of actual memory availability. I did a quick search online thinking others may have run into the same situation with spotlight but didn't find anything promising in the results. Have you tried reaching out to their support team?

[tmattingly]

Nope but I'll plan to do that next week. I'll let you know what they report...

[tmattingly]

I did set the threshold at 95% for now. My local Spotlight guy showed me how.

Did setting the threshold at 95% work out for you?

Are we able to close this topic, or did you have more questions?
