Clearing Monitor Counters

Clearing Monitor Counters
Before you clear statistics counters, verify the valid monitor numbers on a specific port using the
perfMonitorShow command, to make sure the correct monitor counters are cleared. To clear statistics
counters for all or a specified monitor, use the perfMonitorClear command. After the command has
been executed, the telnet shell confirms that the counters on the monitor have been cleared.
The command format is:
perfmonitorclear --class monitor_class [slotnumber/]portnumber [monitorId]
To clear statistics counters for an end-to-end monitor
To clear statistics counters for a filter-based monitor
monitor_class The monitor class, which can be one of EE (end-to-end), FLT (filter-based), or ISL
(inter-switch link). The --class monitor_class operand is required.
slotnumber Specifies the slot number for a SilkWorm 12000, 24000, or 48000 director. For all
other switches, this operand is not required. The slot number must be followed by a
slash ( / ) and the port number, so that each port is represented by both slot number
(1 through 4 or 7 through 10) and port number (0 through 15).
The SilkWorm director has a total of 10 slots. Slot numbers 5 and 6 are control
processor blades; slots 1 through 4 and 7 through 10 are port blades. For 16-port
blades, there are 16 ports, counted from the bottom, numbered 0 to 15. For 32-port
blades, there are 32 ports numbered 0 to 31.
portnumber Specifies a port number. Valid values for port number vary, depending on the switch
type. This operand is required.
monitorId Specifies the monitor number to clear. Monitor numbers are defined when you
create the monitor on a port. This operand is optional. If not specified, all monitor
counters on the port are cleared. This operand does not apply to ISL monitors.

In Fabric OS v3.1.0 and v4.1.0 (or later) the portStatsClear command clears AL_PA- based CRC error
counters for all the ports in the same group.
switch:admin> perfMonitorClear --class EE 1/2 5
End-to-End monitor number 5 counters are cleared
switch:admin> perfMonitorClear --class EE 1/2
This will clear ALL EE monitors' counters on port 2, continue?
(yes, y, no, n): [no] y
switch:admin> perfMonitorClear --class FLT 1/2 4
Filter-based monitor number 4 counters are cleared
switch:admin> perfMonitorClear --class FLT 1/2
This will clear ALL filter-based monitors' counters on port 2, continue? (yes, y, no,
y): [no] y
