bottleneckMon

Monitors and reports latency and congestion bottlenecks on F_Ports and E_Ports.

DESCRIPTION

Use this command to (1) detect latency and congestion bottlenecks on F[L]_Ports and E_Ports and (2) to
manage credit recovery on backend ports. Bottleneck detection and credit recovery are two independent
functions; enabling credit recovery has no impact on bottleneck detection and vice versa.

Bottleneck Detection

For bottleneck detection, this command provides the following management functions:

•

Enabling or disabling bottleneck detection on a switch and optionally configuring thresholds and alert
parameters.

•

Changing alert parameters on specified ports after you have enabled the feature on the switch.

•

Configuring severity thresholds for congestion and latency bottlenecks for a switch or for a specified
port list.

•

Configuring for congestion and/or latency bottlenecks for a switch or for a specified port list.

•

Refining the criterion for defining latency bottleneck conditions to allow for more (or less) sensitive
monitoring at the sub-second level.

•

Clearing the configuration on specified ports only (this option cannot be performed switch-wide).

•

Excluding specified ports from being monitored or including previously excluded ports.

•

Generating history or status reports that show congestion bottlenecks and latency bottlenecks.
