Changing bottleneck detection parameters
13
Congestion threshold for alert - 0.700
Averaging time for alert - 200 seconds
Quiet time for alert - 150 seconds
Per-port overrides for alert parameters:
========================================
Port Alerts? LatencyThresh CongestionThresh Time (s) QTime (s)
=================================================================================
46 N -- -- -- --
47 L 0.750 -- 200 150
Example 5: Changing the latency time value for a single port
This changes the time value to 250 seconds for port 47 only. Notice that the command must
include -alert=latency to preserve the latency-only alerts configured in the previous example.
In general, -alert must be specified (with =latency or =congestion if desired), on every --config
command when alerts are desired.
switch:admin> bottleneckmon --config -alert=latency -time 250 47
switch:admin> bottleneckmon --status
Bottleneck detection - Enabled
==============================
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
Per-port overrides for alert parameters:
========================================
Port Alerts? LatencyThresh CongestionThresh Time (s) QTime (s)
=================================================================================
46 N -- -- -- --
47 L 0.750 -- 250 150
Example 6: Clearing bottleneck detection override values from ports
This removes any changed bottleneck detection parameter values from ports 46 and 47.
Notice that the “Per-port overrides for alert parameters” section is not displayed as there are no
per-port overrides.
switch:admin> bottleneckmon --configclear 46-47
switch:admin> bottleneckmon --status
Bottleneck detection - Enabled
==============================
Switch-wide sub-second latency bottleneck criterion:
====================================================
Time threshold - 0.800
Severity threshold - 50.000
