Displaying bottleneck detection configuration details

3. Repeat
on every switch in the fabric.
NOTE
Best practice is to use the default values for the alerting and sub-second latency criterion
parameters.
Example of enabling bottleneck detection
(Recommended use case) The following example enables bottleneck detection on the switch with
alerts using default values for thresholds and time.
switch:admin> bottleneckmon --enable -alert
The following example enables bottleneck detection on the switch without alerts. In this case, even
though alerts are not delivered, you can still view the bottleneck history using either the CLI or BNA.
switch:admin> bottleneckmon --enable
Displaying bottleneck detection configuration details
Use the following procedure to display the bottleneck detection configuration details:
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the bottleneckmon --status command to display the details of bottleneck detection
configuration for the switch, which includes the following:
•
Whether the feature is enabled
•
Switch-wide parameters
•
Per-port overrides, if any
•
Excluded ports
The initials in the section “Per-port overrides for alert parameters,” indicate which alerts have been
set. The meanings are as follows:
•
C indicates a congestion alert has been set
•
L indicates a latency alert has been set
•
Y indicates both alerts are set
•
N indicates no alerts are set
The examples below show the status of different bottleneck alerts.
Example of status showing that bottleneck detection is not enabled
switch:admin> bottleneckmon --status
Bottleneck detection - Disabled
switch:admin>
See
“Enabling bottleneck detection on a switch”
on page 380 for instructions on enabling
bottleneck detection.
Example of status output showing that bottleneck detection is enabled for both congestion and latency
switch:admin> bottleneckmon --status
Bottleneck detection - Enabled
