Bottleneck detection

NOTE
The best practice is to enable alerts and use the default values:
Congestion 80%
Latency 10%
Window 300 seconds
Quiet Time 300 seconds
Time threshold 0.8
Severity threshold 50
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
“Inheriting alert parameters from a switch” on page 996 for
instructions.
Use the following steps to enable bottleneck alerts and configure alert parameters.
1. Select Monitor > Performance > Bottlenecks.
The Bottlenecks dialog box displays, as shown in Figure 421 on page 994.

2. Select Enable if it is not already selected.
3. Select the Congestion Alerts check box to enable alerts for congestion bottlenecks. Clear this
check box to disable alerts. If you enabled alerts, enter threshold values between 1 and 100,
or use the default value for triggering a congestion alert.
4. Select the Latency Alerts check box to enable alerts for latency bottlenecks. If you enabled
alerts, enter values for the following thresholds:
• Threshold - Enter values between 1 and 100, which is the percentage of one-second
intervals affected by congestion conditions within a specified time window that will trigger
a latency alert.
