To remove any port-specific alerting and sub-second latency parameters and revert to the switch-
wide parameters, enter bottleneckmon --configclear.
To remove and erase all bottleneck alerts and their criteria, enter bottleneckmon --disable.
Disabling bottleneck detection on a switch
on page 404 for more details.
Refer to the Fabric OS Command Reference for more information.
Examples of applying and changing bottleneck detection parameters
The following examples show how to change various bottleneck detection parameters, and how the
changes made are retained when the next set of changes is made. For each example, after the
configuration command is run, the bottleneckmon --status command is run to show the new settings,
which are bolded just for the examples.
Example 1: Setting time window, quiet time, and threshold values for an entire switch.
The following example sets the time window to 150 seconds, the quiet time to 150 seconds, the
congestion threshold to 0.7 (70%) and the latency threshold to 0.2 (20%) for the entire switch.
switch123:admin> bottleneckmon --config -alert -time 150 -qtime 150 -cthresh 0.7 -
lthresh 0.2
switch:admin> bottleneckmon --status
Bottleneck detection - Enabled
==============================
Switch-wide sub-second latency bottleneck criterion:
====================================================
Time threshold - 0.800
Severity threshold - 50.000
Switch-wide alerting parameters:
================================
Alerts - Yes
Latency threshold for alert - 0.200
Congestion threshold for alert - 0.700
Averaging time for alert - 150 seconds
Quiet time for alert - 150 seconds
Example 2: Changing time window value for an entire switch.
The following example changes the time window value to 200 seconds for the entire switch.
switch123:admin> bottleneckmon --config -alert -time 200
switch123:admin> bottleneckmon --status
Bottleneck detection - Enabled
==============================
Switch-wide sub-second latency bottleneck criterion:
====================================================
Time threshold - 0.800
Severity threshold - 50.000
Switch-wide alerting parameters:
================================
Alerts - Yes
Latency threshold for alert - 0.200
Congestion threshold for alert - 0.700
Averaging time for alert - 200 seconds
Quiet time for alert - 150 seconds
Example 3: Disabling bottleneck detection alerts for a port.
The following example disables bottleneck detection alerts for port 46 only.
switch123:admin> bottleneckmon --config -noalert 46
switch123:admin> bottleneckmon --status
