Parameters for nrpe_check Win-NRPE:Memory with NSClient++

Hello dear LibreNMS community,

I have now tried different parameters for the nrpe_check with the nsclient++ for our SQL server.

I want to get a warning state at about 95% usage and a critical state at 100% usage.

The default parameters look like this:

-n -2 -c CheckMem

It works, but the warning and critical state is set too low for an SQL server.

I tried things like:
-n -2 -c CheckMem -w 95 -c 99

After that the check does not work anymore.

I hope you can help me.

Regards
