Hi people: we use Xymon 4.3.30 and I believe had issues when vms are downgrade on the CPU quantity. For example one vms was 12 CPUs and month ago we re-shape it to 2 CPUs (same RAM).
But the realCPU stats sometime show and Y axis of 120%... For example today got red alarm by realCPU on 95% and the graph show a Y axis of 120%.
Should we make some adjustments or issue some command to correct this ?

Any input will really appreciate it. I don't know if this helps but; this example is running redhat 8.6 on Oracle OCI cloud.

    downgrades?

Hi Josh, currently we didn't delete the old data... I'm not the owner of the xymon system also by company rules  I should justify the deletion of that data.  Besides that: I'm assuming that CPU downgrade requires special handling. 

General question can we delete specific data from a host. For example, can we delete all CPU related data from this specific server and still have the disk, network and other monitored data. Like a specific reset.. Or is a all or nothing treatment?

Comparing 2 CPU going forward versus 12 CPU in the past makes for some confusion.  I'm not saying you have to delete that history for that one test on that one host, I'm saying it's a possibility.  It's what I would do.
