Overview of Performance Monitor Operations
This section briefly describes how to use Performance Monitor to monitor the
storage system.
Start Monitoring
To start monitoring the storage system, you start Performance Monitor and
display the Monitoring Options window.
The following statistics appear in the tabs of Performance Management
windows.
•
LU statistics are displayed in the Port-LUN tab.
•
Volume statistics are displayed in the LDEV tab.
In the above tabs, performance statistics of unused volumes are displayed as
hyphens (-), if the range of monitored CUs does not match the range of CUs
used in the disk storage system or registered as external volumes. In addition,
depending on your disk subsystem configuration, the list may display
performance statistics for some volumes and not display performance statistics
for other volumes.
To correctly display performance statistics, you must specify CUs to be
monitored as follows:
•
To display performance statistics of a LUSE volume in the Port-LUN tab,
you must specify all volumes that make up the LUSE volume as the
monitoring targets.
•
To display performance statistics of parity group to be displayed in the
LDEV tab, you must specify all volumes that belong to the parity group as
the monitoring target.
