Bottleneck detection

Configuring bottleneck alert parameters
After you enable bottleneck detection, you can change the alert parameters on all eligible ports,
switches, and fabrics.
The alert parameters include whether alerts are sent and the threshold, time, and quiet time
options.
NOTE
Best practice is to enable alerts and use the default values:
Congestion 80%
Latency 10%
Window 300 seconds
Quiet Time 300 seconds
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. See “Inheriting alert parameters from a switch” on page 804 for
instructions.
1. Select Monitor > Performance > Bottlenecks.
The Bottlenecks dialog box displays.
2. Select Enable if it is not already selected.
3. Select the Alerts check box to enable alerts. Clear this check box to disable alerts.
4. If you enabled alerts, enter values for the alert settings, or use the default values.
5. Select one or more fabrics, switches, or ports from the Products/Ports list.
You can select fabrics or switches or ports, but you cannot select a mix of fabrics, switches,
and ports.
6. Click the right arrow to apply the settings in the Bottleneck Detection pane to the selected
elements in the Products/Ports list.
If you selected one or more ports, a right arrow displays in the Direct Assigned column for
these ports, indicating that the alert parameters for the ports override the alert parameters for
the switch.
If you selected switches or fabrics, the alert parameters are changed for all of the eligible ports
in those switches and fabrics except for the ports that had been directly assigned alert
parameters previously.
7. Cl ic k OK or Apply to save your changes.
