Dispatcher queues

Purpose

This monitor is dedicated to the surveillance of the dispatcher queues. It can monitor the number of requests waiting in the queues at a given time, and the number of requests written within a given period of time.

Configuration hints

Use the surveillance table to create monitoring rule for each type of queue, and set the threshold for the maximum number of requests to watch for a given queue. If you set a period to a value different than 0, the threshold will be used to compare against the number of requests received within the period, instead of the total number of waiting requests
