Does anyone know what to use to incorporate a queue that contstantly reads messages off a queue(MDB) but throws alerts if it ever gets backed up to a certain depth?
thank you |

Can you be more specific ?
What do you mean with incorporate ???
I'd be going with a monitoring software and just raise the alert if the qdepth is greater than ....
Enjoy  |

This could be conveniently accomplished if jboss is your app server where for every mdb you can define generic interceptors that would check depth or preformat the message a certain way. Overall, this is not a good approach. You should have a separate app monitoring queue depths, enqueue/dequeue rates, etc.

im using was51. with mq 5.3
I understand how to write a java pgm to get the queuedepths, and I do not have the option of purchasing 3rd party software to monitor unfortunately.
I was thinking of just using a cron job to get the queuedepths. If the queuedepth is higher than X, I would like to use javaMail to send myself an email.
does this sound okay, or do you guys think I can accomlish this in a better way?
In windows, if i look at the MQ explorer in see a tab for events then a high depth..is there some way to have it work like a trigger monitor so it can call a program if the queue gets over 2000?
thanks |

Using Performance Events might help you out. Have an app monitor the system.admin.perfm.event for a queue depth high event then send you a mail or however you want to notify yourself.
You can also use triggering so that you don't have to have that process listen to the perfm.event queue, it will just be kicked off whenever that event is thrown.
Hopefully this is of some help. |

The Monitoring WebSphere MQ manual talks about performance events.
The Application Programming Guide discusses Triggering.
There may be more manuals that look into these topics. |

MO71 Supportpac may be an option too, because it can read event messages and react on it
