perfAddIpMonitor
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.

Adding custom filter-based monitors

In addition to the standard filters—read, write, read/write, SCSI frame and IP frame—you can create
custom filters to gather statistics that fit your needs.
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
