Changing bottleneck detection parameters
13
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
Example 3: Disabling bottleneck detection alerts for a port
This disables bottleneck detection alerts for port 46 only.
switch:admin> bottleneckmon --config -noalert 46
switch:admin> bottleneckmon --status
Bottleneck detection - Enabled

Example 4: Selecting latency-only alerts and changing the latency threshold value for a single port
This changes the alerts to latency-only and the latency threshold value to 0.75, both on port 47
only.
switch:admin> bottleneckmon --config -alert=latency -lthresh 0.75 47
switch:admin> bottleneckmon --status
Bottleneck detection - Enabled
