Monitoring console does not show CPU and Memory Usage data

[nadz]

Hi,

After we upgrade our Splunk version to 8.2.1,

Under the monitoring console `overview` tab,
the chart under `CPU usage by process` and `Memory Usage by process` are empty.

However, they do appear under the `Resource Usage: Instance` tab.

Is anyone able to help why the chart is empty under the `overview` tab of the monitoring console?

Have you opened a case with Support?

Hi Jwalthour

Nope. Haven't opened a support case yet. 
Thought of asking here first.
