Oh, and also `vmstat` has the `pc` column: > pc > Number of physical processors used. Displayed only if the partition is running with shared processor. And that is consistently...

> I think the formula for `ec` may be: `(usedPoolCPU% / 100 * poolCPUs) / entitled` That makes sense, so then I guess the question is what does NMON mean...

I can reproduce this on an internal AIX system. I added a new chart: ```xml ``` An the EC chart only shows 59% but clearly used CPUs are over entitled:...

Would you be okay with this new "Physical CPUs used" chart being added until we can figure out the EC_% issue?

Sorry for the delay. I finally created the PR: https://github.com/nmonvisualizer/nmonvisualizer/pull/106 I'll also try to figure out how to open a support case with AIX on whether nmon's EC_% is wrong...

For reference, opened AIX support case TS015955309

The AIX support team has responded, and, unintuitively, all `EC_*` fields [must be added up for entitlement usage](https://www.ibm.com/docs/en/aix/7.3?topic=tool-processor-statistics), **including** `EC_Idle%` as documented (see the **Note**): > Physical processor consumption in...

I added a minor comment on the diff but otherwise I think this is ready to close. Thanks!
