Key metric statistical table
The key metric statistical table displays basic (default) and advanced performance statistics based
on historical data. To view advanced statistics, select Advanced from the View type list. For more
information about, see
“Statistical data” (page 30) .
The data is displayed for the predefined interval (default - last hour data) that you initially configured
under the Key Metrics tab (Settings > HP P6000 Performance Advisor Instance > Configuration).
You can choose to view data for a different predefined interval or custom duration by selecting
the appropriate option from the Display list. The duration for viewing statistical data is always
independent of the duration for plotting the key metric charts, and the vice versa is also applicable.
For more information on viewing the key metric chart or statistical data for a different duration,
see
“Using the Display option” (page 15) .
For more information on viewing key metrics, see “Viewing a summary of key metrics” (page 108) .

time; for example, KB/s, MB/s, and GB/h.
•
