Spotlight on DB2 6.9.3 - User Guide

Processes grid

This grid presents a list of all processes that are running on the machine.

The Processes drilldown is NOT updated every time that Spotlight data is refreshed, as that may mean the update of hundreds of items of information at a time. To update this drilldown manually, press the F5 key, or choose the Refresh option from the View menu.

NOTE: 
Because information in the Processes drilldown is not updated when Spotlight data is refreshed, data from the drilldown is NOT available in historical snapshots.
