Adding standard filter-based monitors Table 43 lists the commands for adding standard filter-based monitors to a port. Table 43 Commands to add filter-based monitors Telnet command Description perfAddReadMonitor perfAddWriteMonitor perfAddRwMonitor perfAddScsiMonitor perfAddIpMonitor Counts the number of SCSI read commands. Counts the number of SCSI write commands. Counts the number of SCSI read and write commands. Counts the number of SCSI traffic frames. Counts the number of IP traffic frames. The following example adds filter-based monitors to slot 1, port 2 and displays the results: switch:admin> perfaddreadmonitor 1/2 SCSI Read filter monitor #0 added switch:admin> perfaddwritemonitor 1/2 SCSI Write filter monitor #1 added switch:admin> perfaddrwmonitor 1/2 SCSI Read/Write filter monitor #2 added switch:admin> perfaddscsimonitor 1/2 SCSI traffic frame monitor #3 added switch:admin> perfaddipmonitor 1/2 IP traffic frame monitor #4 added switch:admin> perfmonitorshow --class FLT 1/2 There are 5 filter-based monitors defined on port 2.

To define a custom filter, use the perfAddUserMonitor command. With this command, you must specify a series of offsets, masks, and values. For all transmitted frames, the switch performs these tasks: • Locates the byte found in the frame at the specified offset • Applies the mask to the byte found in the frame • Compares the value with the given values in the perfAddUserMonitor command • Increments the filter counter if a match is found The following number of offsets can be specified: • SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, Core Switch 2/64, and SAN Director 2/128 (Fabric OS 4.0.0 or later): Up to two different offsets per port (one offset when FMS is enabled) • 4/256 SAN Director (Fabric OS 5.0.1 or later): Up to 15 different offsets per port (14 offsets when fmsmode is enabled) • SAN Switch 2/8-EL and SAN Switch 2/16 (Fabric OS 3.0.0 or later): Up to three different offsets per port Fabric OS 5.x administrator guide 205
