Filter-based performance monitoring
17
Virtual Fabrics considerations: Filter-based monitors are not supported on logical ISLs (LISLs), but
are supported on ISLs and extended ISLs (XISLs).
You can monitor filter-based performance using the perfMonitorShow command, as described in
“Displaying monitor counters” on page 398. You can clear filter-based counters using the
perfMonitorClear command, as described in “Clearing monitor counters” on page 399.
Adding standard filter-based monitors
You cannot add identical filter monitors to the same port. Two filter monitors are considered to be
identical when they have the same values for the following items:
• Filter monitor type
• Owner (Telnet, Web Tools, etc.)
• Alias
1. Connect to the switch and log in as admin.
2. Enter one of the following commands, depending on the type of monitor you want to add:
• perfAddReadMonitor To count the number of SCSI Read commands.
• perfAddWriteMonitor To count the number of SCSI Write commands.
• perfAddRwMonitor To count the number of SCSI Read and Write commands.
• perfAddScsiMonitor To count the number of SCSI traffic frames.
• perfAddIpMonitor To count the number of IP traffic frames.
Example
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.

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.
