Changing bottleneck detection parameters

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
Severity threshold
Switch-wide alerting parameters:
================================
Alerts
Congestion threshold for alert - 0.800
Averaging time for alert
Quiet time for alert

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
Severity threshold
Switch-wide alerting parameters:
================================
Alerts
Latency threshold for alert
Averaging time for alert
Quiet time for alert

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.
