13 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 - 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. 384 Fabric OS Administrator's Guide 53-1002745-02
