When you enable bottleneck detection, you also determine whether alerts are to be sent when the
bottleneck conditions at a port exceed a specified threshold. The alert parameters include whether
alerts are sent and the threshold, time, and quiet time options. These alert parameters apply to all
ports in the switch, unless you override them later.
After you enable bottleneck detection, you can change the alert parameters on all eligible ports,
switches, and fabrics.
NOTE
The best practice is to enable alerts and use the default values:
If you change the Window value, you should use a setting that is 300 seconds or higher.
If you change the alert parameters for a port, you can later cancel these settings and inherit the
settings from the switch. Refer to
instructions.
Use the following steps to enable bottleneck alerts and configure alert parameters.
1. Select Monitor > Performance > Bottlenecks.
