EXAMPLES Bottleneck detection examples
To enable bottleneck detection on the switch without alerts (statistics collected with default parameters
are still available for viewing):
switch:admin> bottleneckmon --enable
To enable bottleneck detection on the switch with congestion and latency alerts using default values for
thresholds and time (preferred use case):
switch:admin> bottleneckmon --enable -alert
To enable bottleneck detection on the switch with congestion alerts only:
switch:admin> bottleneckmon --enable -alert=congestion
To enable bottleneck detection on the switch with latency alerts only:
switch:admin> bottleneckmon --enable -alert=latency
To customize congestion bottleneck detection on a port range after default alerts are enabled
switch-wide:
switch:admin> bottleneckmon --enable -alert
switch:admin> bottleneckmon --config -alert \
-cthresh .5 -time 240 1-15
To change the bottleneck detection configuration on the logical switch to allow congestion alerts only:
switch:admin> bottleneckmon --config -alert=congestion
To change the bottleneck detection configuration on the logical switch to allow latency alerts only:
switch:admin> bottleneckmon --config -alert=latency
To change the bottleneck detection configuration on the logical switch to allow both congestion and
latency alerts:
switch:admin> bottleneckmon --config -alert
To change the bottleneck detection configuration on the logical switch to disable all alerts:
switch:admin> bottleneckmon --config -noalert
