Symptoms

There are discrepancies between the per-core CPU usage graphs and the system CPU usage graph.

Impact

The system does not report the actual CPU usage. In some places the per-core usage is high while the system usage does not reflect that, and in other places the system usage is high, while the per-core usage is flat.

Conditions

Normal running conditions.

Workaround

None

Fix Information

System now reports matching CPU usage in the per-core CPU usage graphs and the system CPU usage graph.
