bottleneckMon

-lthresh latency_threshold

Specifies the severity threshold for latency that triggers an alert. The

threshold indicates the percentage of one-second intervals affected by the

bottleneck condition within the specified time window. The threshold is

expressed as the equivalent fraction between 0 and 1. The default value is

0.1. This parameter is valid only for latency alerts.

EXAMPLES Add the following examples to the Example section:

To enable bottleneck detection on the logical switch with congestion alerts only:

switch:admin> bottleneckmon --enable -alert=congestion

To enable bottleneck detection on the logical switch with latency alerts only:

switch:admin> bottleneckmon --enable -alert=latency

To enable bottleneck detection on the logical switch with both congestion and latency alerts:

switch:admin> bottleneckmon --enable -alert

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

To change the bottleneck detection configuration on port 5 to allow congestion alerts only; overrides

switch-wide configuration:

switch:admin> bottleneckmon --config -alert=congestion 5

To change the bottleneck detection configuration on port 5 to allow latency alerts only; overrides

switch-wide configuration:

switch:admin> bottleneckmon --config -alert=latency 5

To change the bottleneck detection configuration on port 5 to allow congestion and latency alerts;

overrides switch-wide configuration:

switch:admin> bottleneckmon --config -alert 5

To change the bottleneck detection configuration on port 5 to disable alerts; overrides switch-wide

configuration:

switch:admin> bottleneckmon --config -noalert 5

The output of the --status display has been changed to indicate which type of alert is configured. In the

section "Switch-wide alerting parameters", the output now displays which type of alert is configured.

(Previously it only displayed whether or not alerts were enabled.) In the section "Per-port overrides for

alert parameters", the abbreviations "C" and "L" indicate "congestion" and "latency". The meanings of the

abbreviations "Y" (both alerts configured) and "N" (no alerts configured) remain unchanged.
