Description
Define a queue-length monitor to measure peak queue occupancy of a virtual output queue (VOQ).
In a typical deployment scenario that uses strict-priority scheduling, a
HIGH priority queue can starve LOW priority queues.
Thus the packets in such LOW priority queues can remain longer than
desired. Use this VOQ queue-length monitoring feature, along with queue transmit
statistics, to detect such stalled conditions.
Options
| monitoring-profile |
(Required) Name of the monitoring profile. Use the monitoring profile name to attach the monitoring profile to one or more interfaces. Each monitoring profile contains one or more export filters. |
| export-filters |
(Required) Name of the export filter. Each export filter consists of an optional peak queue length percentage filter and one or more queues. |
| peak-queue-length percent |
(Optional) The percentage of the peak queue length filter. When configured, Junos exports VOQ telemetry only when the hardware-captured peak queue length exceeds the configured value. When not configured, Junos always exports VOQ telemetry.
|
| queue |
(Required) The queue, or queues, for the export filter to monitor.
