I am setting up a MQ monitoring and alerting mechanism when the Queue High depth, maximum depth events occur based on performance events.
When MQRC_Q_HIGH_DEPTH event fires, High Depth event on the local Queue properties is getting disabled. Similarly, when MQRC_MAX_DEPTH event occurs, Maximum depth event is getting disabled.
In order to get these events enabled automatically, is it necessary to fire up MQRC_LOW_DEPTH event?
My question is how to automatically turn on the Max Queue depth and high depth events at subsequent times.
I appreciate anyone's comments on the performance events. |

When Queue Depth High is reached or breached the 'trigger' is set OFF, and both the Queue Max Depth and the Queue Depth Low 'triggers' are automatically set ON; when Queue Depth Low is reached or breached that 'trigger' is set OFF, and the Queue Depth High 'trigger' is then reset. It's all there in the manual should you care to read it, there's even a task to demonstrate how. Amazing things manuals...

Normally when setting up depth events on a local queue, they all need to be enabled, as you may not have prior knowledge of where the current depth is in relation to the percentage thresholds, eg.
| Code: |
ALTER QLOCAL('MY.QUEUE) +
QDPLOEV(ENABLED) QDEPTHLO(30) +
QDPHIEV(ENABLED) QDEPTHHI(90) +
QDPMAXEV(ENABLED) |
After that, MQ will automatically enable and disable the depth event attributes as the current depth goes up and down, and all the correct performance event messages will be produced.
