We need details regarding the function of the MQ Monitor:
1 - Explain how the Enqueue/Dequeue Count Per Day metrics are derived?
2 - What metrics are polled directly from the MQ queue manager directly?
3 - What metrics are calculated by APM (agent or EM)?
1 - Enqueue count and dequeue count metrics are extracted directly from the MQ server. But the metrics like Enqueue count per min, Enqueue count per hour, Enqueue count per day and so on, are being calculated by MQMonitor internally. Enqueue count per day is nothing but the number of times the enqueue/put operation happened in the past 24 hours, on that particular queue.
2 - Most of the metrics are pulled directly from the MQ server. Only few such as Enqueue count per day metrics are calculated by MQMonitor.
