HP StorageWorks Fabric OS 5.2.x administrator guide (5697-0014, November 2009)

320 Administering Advanced Performance Monitoring (APM)
The following example displays the monitors on slot 1, port 4 using the perfShowFilterMonitor
command (the monitor numbers are listed in the KEY column) and deletes monitor number 1 on slot 1, port
4 using the perfDelFilterMonitor command:
Monitoring ISL performance
ISL monitoring is set up on E_Ports automatically in release v4.4.0 and later.
An ISL monitor measures traffic to all reachable destination domains for an ISL, showing which destination
domain is consuming the most traffic. If there are more than 16 domains, the monitor samples traffic and
extrapolates the measurement.
EE monitors on E_Ports are deleted when they become part of an ISL.
You can monitor ISL performance using the perfMonitorShow command, as described in “”Displaying
monitor counters” on page 321.” You can clear ISL counters using the perfMonitorClear command, as
described in ”Clearing monitor counters” on page 323.
Monitoring trunks
For trunked ISLs on Fabric OS v4.x or higher switches, monitoring is set only on the master ISL, which
communicates with the associated slave ISLs. Note the following:
• For Fabric OS v3.x switches, monitoring can be set on slave ISLs.
• End-to-end monitors are not supported for ISLs.
• 4/16 SAN Switch and 4/8 SAN Switch, SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32,
and SAN Director 2/128 models support eight filter-based monitors for trunks.
• The SAN Switch 4/32, 4/64 SAN Switch, 400 MP Router, and 4/256 SAN Director switches support
12 filter-based monitors for trunks.
switch:admin> perfshowfiltermonitor 1/4
There are 4 filter-based monitors defined on port 4.
