-span seconds
Specifies the total duration in seconds covered in the output. When a port is
specified with the --show command, the maximum span is 10800 seconds
(3 hours). When a wildcard (*) is specified, the maximum span is defined
such that the value of -span divided by the value of the interval cannot
exceed 30. The span value must be greater than 0. The default value is 10
seconds.
History data are maintained for a maximum of three hours per port, so the
span can be 10800 seconds at most. When the show command is issued for
all ports (*), the maximum duration is defined such that the value of -span
divided by the value of the interval cannot exceed 30.
-refresh Refreshes the display to continuously update with fresh data at a certain rate.
The refresh rate is equal to the number of seconds specified in the interval.
-congestion | -latency
Restricts the display to congestion or latency data. If neither is specified, the
command displays combined statistics for both types of bottlenecks
--
status Displays the details of the Bottleneck Detection configuration for the current
(logical) switch. Refer to the command description section for an explanation
of the displays. If virtual fabrics are enabled, ports not belonging to the
current logical switch are not displayed. This is change from v6.3.0, where the
output of --status included ports that did not belong to the current logical
switch.

help Displays the command usage.
Examples To enable bottleneck monitoring on the switch without alerts (statistics collected with default
parameters are still available for viewing):
switch:admin>
bottleneckmon --enable
To enable bottleneck monitoring on the switch with alerts using default values for thresholds and
time (preferred use case):
switch:admin>
bottleneckmon --enable -alert
To customize congestion bottleneck monitoring on a port range after default alerts are enabled
switch-wide:
switch:admin>
bottleneckmon --enable -alert
switch:admin>
bottleneckmon --config -alert -cthresh .5 -time 240 1-15
To disable bottleneck monitoring on a specified port:
switch:admin> bottleneckmon --exclude 2/4
To disable bottleneck monitoring on all ports of a chassis:
switch:admin>
bottleneckmon --disable
