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:
•
•
•
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

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.
