152 Administering advanced performance monitoring
Deleting filter-based monitors
To delete a filter-based monitor:
1. List the valid monitor numbers using the
perfshowfiltermonitor
command.
2. Use the
perfdelfiltermonitor
command to delete a specific monitor. If you do not specify which
monitor number to delete, you are asked if you want to delete all entries.
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.
You can monitor ISL performance using the
perfmonitorshow
command, as described in “” Displaying
monitor counters ” on page 153. You can clear ISL counters using the
perfmonitorclear
command,
as described in ” Clearing monitor counters ” on page 155.
Monitoring trunks
For trunked ISLs on Fabric OS v4.x switches, monitoring is set only on the master ISL, which
communicates with the associated slave ISLs. For Fabric OS v3.x switches, monitoring can be set on slave
ISLs.
End-to-end monitors are not supported for ISLs.
The HP StorageWorks SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, Core Switch 2/64,
and SAN Director 2/128 support eight filter-based monitors for trunks.
The SAN Switch 4/32 supports 12 filter-based monitors for trunks.
