On systems with HT Split CPU the Average CPU usage shown in DOS Visibility page was calculated as average of all available CPU-s. On other hand, on other screens it is calculated as an average of maximum of data plane and control plane CPU-s. It causes inconsistency in displayed data.
Inconsistency in CPU usage values displayed in DOS Visibility and other screens
HT Split is enabled on the system (tmsh list sys db scheduler.splitplanes.ltm results in "True")
None
After the fix on systems with HT Split average CPU usage is calculated only for data plane CPU-s. The GUI title is changed correspondingly.
