Changing bottleneck detection parameters
13
Setting a congestion alert only
This example enables a congestion alert and shows its values.
Example of setting an alert for congestion
switch:admin> bottleneckmon --enable -alert=congestion
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 - Congestion only
Congestion threshold for alert - 0.800
Averaging time for alert - 300 seconds
Quiet time for alert - 300 seconds
Setting a latency alert only
This example enables a latency alert shows its values.
Example of setting an alert for latency
switch:admin> bottleneckmon --enable -alert=latency
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 - Latency only
Latency threshold for alert - 0.100
Averaging time for alert - 300 seconds
Quiet time for alert - 300 seconds
Changing bottleneck detection parameters
When you enable bottleneck detection, you can configure switch-wide or port-specific alerting
parameters. The alerting parameters indicate whether alerts are sent, and the threshold, time, and
quiet time options, as well as sub-second latency criterion for ports.
After you enable bottleneck detection, you can change the alerting parameters for the entire switch
or just for individual ports. For example, you can change only the latency threshold for only port 47
without affecting any other port. You can also change the parameters on ports that have been
excluded from bottleneck detection.For a trunk, you can change the parameters only on the master
port.
