I want to monitor the queues we use at the application level, but I want to also monitor the health of the MQ so I was wondering which queues should I monitor.
Where can I find the documentation about each one of the system queues ?,
What queues should I monitor ?
Thanks. |

monitoring system queues are not that important, if you have properly designed.
Monitor the apps queues, using some tools.

You don't monitor your DLQ? Your System Cluster Transmit Queues? The Cluster Command queues? The trigger monitor's INIT queues?
You need to know when those are not at zero depth or rapidly trending towards zero depth.

You need to ponder what it means when a message arrives (unexpectedly) in your DLQ. IBM supplies a dead-letter queue handler for all platforms. It allows you to write a script to move dead-letter messages somewhere - if you want to.
Other queues of interest would include the event queues, like the SYSTEM.CHANNEL.EVENT.QUEUE. It captures messages about misbehavior of your channels.
Monitoring software from IBM Tivoli, and isv's, offer automation software to do the monitoring for you - based on rules you supply.

I can monitor those queues, but the question is the same:
What does it means to have 1 or 100 or 10000 messages on X or Y queue ?
For example, there is the queue:
SYSTEM.ADMIN.CHANNEL.EVENT
I know it has to do with events on the channels, but does it means it was not able to process an event at some time ?, does it means the event needs to be sent to a remote QM ?, should I open each one of the messages on that queue ? |

Do some reading in the WMQ Monitoring manual. Do a Mr. Google search on MQ event messages. Take a look at SupportPac MO01: Event and Dead Letter Queue Monitor.
Only Channel Events are enabled as the product is distributed. You can enable others or disable them all. Channel event messages mean channel problems; but your channel definitions may specify retry intervals to automatically recover from channel problems. Refer to the WMQ Communications manual for lots of useful narrative on channel problems.
Short answer to your question: yes. But there is automation software...
