204 Administering advanced performance monitoring
The EE mask has 12 fields, each with a value of on or off. The following example shows how to set and
display and EE mask (the EE mask is set on slot 1, port 11):
Displaying a monitor
Issue the perfMonitorShow command, as described in ”Displaying monitor counters” on page 207.
Deleting EE monitors
Use the perfDelEeMonitor command to delete EE monitors. You can delete all monitors or specific
monitors. The following example deletes the EE monitor number 0 on slot 1, port 2:
Monitoring filter-based performance
Filter-based performance monitoring counts the number of times a frame with a particular pattern is
transmitted by a port. Filter-based monitoring is achieved by configuring a filter for a particular purpose.
The filter can be a standard filter (for example, a SCSI read command filter that counts the number of SCSI
read commands that have been transmitted by the port) or a user-defined filter customized for your
particular use.
For the SAN Switch 4/32, the maximum number of filters is 12 per port, in any combination of standard
filters and user-defined filters.
For the 4/8 SAN Switch, 4/16 SAN Switch, SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32,
Brocade 4Gb SAN Switch for HP p-Class BladeSystem, Core Switch 2/64, and SAN Director 2/128, the
maximum number of filters is eight per port, in any combination of standard filters and user-defined filters.
For the 4/256 SAN Director, the maximum number of filters is 12 per port.
The actual number of filters that can be configured on a port depends on the complexity of the filters. For
trunked ports, the filter is configured on the trunk master.
You can monitor filter-based performance using the perfMonitorShow command, as described in
”Displaying monitor counters” on page 207. You can clear filter-based counters using the
perfMonitorClear command, as described in ”Clearing monitor counters” on page 209.
