CPU Usage graph for AIX is misleading

Now several CPU metrics is collected for AIX as attached.

  • User

  • System

  • Wait

  • Hypervisor

  • Stolen idle cycles

  • Used

  • Idle

These metrics is stacked on a single graph.

But actually "Used" metric is sum of "User" "System" and "Wait", so the cpu usage is counted twice on the graph. This is misleading for user.

----

And "User", "System", "Wait" is collected from vmstat, which is expression from the OS point of view.

Hypervisor metic is collected through the lparstat, which is expression from the LPAR point of view.

These metrics are should not be expressed in the same single graph. The meaning of the metric is different.

So as default, please de-select the metrics whose data source is different. De-select the metrics other than User. System, Wait.

Let the user choose the metrics to display, OR create the separate graph for each metrics.
