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.
