Monitoring Filter-Based Performance; Adding Standard Filter-Based Monitors - HP AE370A - Brocade 4Gb SAN Switch 4/12 Administrator's Manual

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 4/16 SAN Switch and 4/8 SAN Switch, SAN Switch 2/16V, SAN Switch 2/32, and SAN Director
2/128 models, the maximum number of filters is 8 per port, in any combination of standard filters and
user-defined filters.
For the SAN Switch 4/32, 4/64 SAN Switch, 400 MP Router and 4/256 SAN Director models, the
maximum number of filters is 12 per port, in any combination of standard filters and user-defined filters.
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.
For the 4/256 SAN Director, the maximum number of filters is 12 per port, in any combination of standard
filters and user-defined filters, except for the FC4-48 port blade. For the FC4-48 port blade:
• Ports 0 through 15 have a maximum of 12 filter monitors per port.
• Ports 16 through 31 have a maximum of 6 filter monitors per port.
• Ports 32 through 47 do not have filter monitors.
For the FC4- 1 6IP port blade, the maximum number of filters is 12 per port and 15 offsets per port. At the
time of this document's release, HP does not support the FC4- 1 6IP iSCSI blade. Consult

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
perfMonitorClear command, as described in

Adding standard filter-based monitors

Table 65 lists the commands for adding standard filter-based monitors to a port.

Telnet command
perfAddReadMonitor
perfAddWriteMonitor
perfAddRwMonitor
perfAddScsiMonitor
perfAddIpMonitor
You cannot add identical filter monitors to the same port. Two filter monitors are considered to be identical
when they have the same:
• Filter monitor type
• Owner (telnet, Web Tools, etc.)
• Alias
