Viewing Historical Data

To see historical performance data in a graph, click the History tab. Graphing starts when you click the tab and is based on the polling interval you selected.

To see the objects available in the scope, click the button next to Select Detail (the button text depends on what scope you selected), and select the object whose historical data you want to see.
