Troubleshooting Performance Monitor
• When the WWN of a host bus adapter is displayed in red in the tree of the WWN tab:
The host bus adapter (HBA) whose WWN is displayed in red is connected to two or more
ports, but the traffic between the HBA and some of the ports are not monitored by Performance
Monitor. When many-to-many connections are established between HBAs and ports, make sure
that all the traffics between HBAs and ports monitored. For details on the measures, see the HP
StorageWorks XP24000 Performance Control User's Guide.
• When a part of monitoring data is missing:
While displaying Performance Monitor in short range, if I/O workloads between hosts
and the storage system become heavy, the storage system gives higher priority to I/O
processing than monitoring processing. In such a case, a part of monitoring data might be
missing. If the monitoring data are missing frequently, use the Gathering Interval option in
the Monitoring Options window to change the collection interval longer. For details, see
“ Start Monitoring ” on page 47 and “ Monitoring Options Window ” on page 42
Note that the display of the LDEV tab, Port-LUN tab, and WWN tab is fixed to in short range.
