I wrote a Nagios monitor to be able to check for various entitlement usages in an AIX shared CPU pool environment.
One can monitor the entitlement usage inside a LPAR, the usage of the configured CPU pool and the CPU usage of the whole managed system.
It's plain C and compiles with IBM xlC and GCC.
I think about making this small project public if there is any demand. So please make a comment if you're interested.
Is there any prefered way of how to publish such things?
