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
