Description Christian Völker univentionstaff 2018-06-05 08:53:54 CEST 
From https://forge.univention.org/bugzilla/show_bug.cgi?id=18661#c1 we know the CPU-utilization is not always fully reliable.

Some administrators do not like to have a display which is not reliable while others are fine with an estimated CPU-usage display.

So in the end it should be configurable if UVMM displays CPU-usage or not. Ideally per virtual machine.

I do not think this is helpful, as it would generate questions why the CPU usage is shown some VMs is shown but not on all.

This fix introduces the UCRv uvmm/umc/showcpuusage which sets the visibility for the CPU usage column in the UVMM UMC module. The default is yes, which shows the column. Setting it to 'no' hides the column, a reload of the UVMM module browser session is required.
