WMB 7.0.0.3 running on Solaris.
A project is attempting to use Resource Statistics to determine resource usage by their flows; specifically (but not limited to) JVM usage & ODBC activity.
They've discovered that, as clearly indicated here, their monitoring application is getting XML "too frequently":
| Quote: |
| An application that subscribes to a publication, in the form of an XML message, that is published by the broker every 20 seconds |
They want a longer reporting interval to 20 seconds. I can't find any way to vary this; I'd initially thought that mqsichangebroker -v controlled this but research indicates that's the accounting reporting period.
Before I recommend that they suck it up and process the XML every 20 seconds like good little developers, does anyone have any brilliant ideas / cunning plans / undetectable murder strategies?
Constraints:
- No monitoring software. The site already has some, published by NeverHeardOfThem Software Inc, which is worthless generally and doublly so in this specific instance
- No use of MBExplorer. Connecting that to the queue manager will (according to the MQ admins) cause the skies to turn to fire, the seas to turn to blood and a swarm of locusts to devour the building. Hence the use of a subscribing app.

One idea: Have a second message flow collect the 20 second reports and aggregate the data, then publish a summary report at the desired interval.

One other idea: just unsubscribe! After getting a publication unsubscribe your app and then recubscribe after your desired longer interval. The broker will keep totaling up the stats for you in the background (for the ones that are cumulative) so you should not miss anything vital... 
Kind regards,

Unless some other application in subscribing to the same topic, I guess? |

No, the Broker will send every 20 seconds to every app that is subscribed...
Kind regards,

1) Subscribe
2) Consume subscription
3) Unsubscribe
4) Pause for the desired interval
5) Repeat from 1)
Clearly you'd need to flesh the details out a bit in the code.....

| If you subscribe, consume and unsubscribe with a minutes interval, arey you not going to miss two of the three 20 s samples? |

No, not for the stats that are cumulative...

Actually my question was more specific to know how this can be achieved through code?
How can Unsubscribe from a topic and then again set the Subscription from code? The fourth point has already had so many discussions I guess. |
