Memcache vs the Memory Usage monitor

[InscrutableDude]

I have a question. Several of our servers use memcache. Is there a way to make the Memory Usage monitor look at %commit instead of memory used? Since most of the ram is used by cache, it means that on a server with 14GB of RAM, about 800MB is technically "free", which generates critical alerts.

Thanks!

it really depends based on the plugin you're using to check memory. what one is it? probably worth looking at the help menu to see if there's a flag to specify.

If you aren't using something that comes with XI by default, can you please share a link to the code for the plugin or just attach the plugin? Thanks!

Sorry for the late reply, I got pulled onto multiple other projects.

I have no custom stuff installed at all. The is the basic Memory Usage monitor that comes with NRPE.

I'm not aware or a way to do anything with %commit in the standard install, but it looks like https://exchange.nagios.org/directory/P ... ce/details could easily be modified to get the %commit info from sar.

Are you using a different tool other than sar to get that %commit info?

[InscrutableDude]

I'm not currently using SAR on that server, but it's the idea that I was trying to convey. When looking at SAR output, you see the difference between "Usage" and ACTUAL usage.

Let me know if there's a way to get similar info, I'm not tied specifically to %commit.

I'll check that doc you referenced and see if that will work for me. I'll update here asap. Thanks!

To get what you are looking for, you would have to install another plugin on the remote server or see if there is a plugin that used SNMP and enable SNMP on the remote server.
Have you searched the exchange site for a plugin that will work for you?
