Process Browsing has only one setting which is used to hide know processes like (system, idle, VSAX).
The process browsing setting can be configured in the "Server Admin > Endpoint Policies > System > General" section of the Web App.
You can also configure this setting on the VSAX Agent itself. However, the Web App Policy settings (if applied to the same machine) will always take precedence over the individual agent settings.
Also, Policies are naturally more convenient for applying such monitoring rules, as they can be applied to multiple machines simultaneously.
To configure this setting on the Agent, go to the "System > General" tab.
