I went to the url you specified and read that the Enable User Activity Logging checkbox should be enabled to view user nac activity so I checked our CAM and noticed that the checkbox is not enabled and a warning next to it which states " (Warning: Enabling the Reporting/User Activity Logging feature may impact the overall system performance)".
So I am hesitant to enable the checkbox. Can anyone comment whether they've experienced any CAM performance with this feature enabled?
