Using Performance Monitor
NAS 8000 Performance Monitor lets you view performance of your HBAs, CPUs,
and total NFS activity from one location in your user interface.
■
With monitoring enabled, Performance Monitor gathers real-time data about
the enabled item and display it in chart format with updates every 5 seconds.
By enabling any metric, there is a small increase in the processor usage once
every 5 seconds.
■
With historical data enabled, Performance Monitor keeps and displays the
data up to 24 hours of it at a time in a chart. Historical data can only be
enabled in a category if monitoring is enabled. By enabling history for a
metric, there is a small amount of disk space used on the system disk (4 to 8
MB).
■
Performance Monitor allows you to have several charts open and viewable at
the same time.
Note: Because Performance Monitor runs in a separate window, you can keep it open
for use while you perform other activities in Command View NAS.
