Switch-wide sub-second latency bottleneck criterion:
====================================================
Time threshold
- 0.800
Severity threshold - 50.000
Switch-wide alerting parameters:
================================
Alerts
- Yes
Latency threshold for alert - 0.200
Congestion threshold for alert - 0.700
Averaging time for alert
- 200 seconds
Quiet time for alert - 150 seconds
Per-port overrides for alert parameters:

Displaying bottleneck statistics
You can use the bottleneckmon -- show command to display a history of bottleneck conditions, for
up to three hours. This command has several display options:
•
Display only latency bottlenecks, only congestion bottlenecks, or both combined.
•
Display bottleneck statistics for a single port, bottleneck statistics for all ports on the switch, or
a list of ports affected by bottleneck conditions.
•
Continuously update the displayed data with fresh data.
Use the following procedure to display the bottleneck statistics:
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the bottleneckmon -- show command.
Example of displaying the bottleneck history in 5-second windows over a period of 30 seconds
In this example, the definition of bottlenecked ports is any port that had a bottleneck occur during
any second in the corresponding interval.
switch:admin> bottleneckmon --show -interval 5 -span 30
