Incorrect memory reporting

Why does Nagios report memory of 26639.72 when only 163840 is assigned to a VM of the 163840, 4096 is reserved

Hello sdecker, can you please provide us with more information? Which plugin are you're using to report memory usage?

check_nt 's MEMUSE includes the page file. Check to confirm this.

If you use checkMem via NRPE you can choose only physical

Step 1 is setting up NSClient++ to listen to check_nrpe connections. The official documentation is pretty good for that:
https://docs.nsclient.org/howto/nrpe/

@box293 has some very useful examples of leveraging check_nrpe with NSClient++ listed on his website:

The top example on this page shows a check against a machine using NSClient++ that only looks at the physical usage:
