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.
1. Connect to the switch and log in as admin.
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.
