Hi all,
I created a event monitoring message flow.
I added a events like FlowStart, FlowRollback and FlowEnd in the monitoring tab of the input node.
When I send a wrong message to input queue events are coming but flowstart event is coming twice.
Input File :
| Code: |
<?xml version="1.0" encoding="UTF-8"?>
<TemperatureConversion>
<Input>
<Unit>Celsius</Unit>
<Degree>28.5</Degree>
</Input>
<Output>
<Unit></Unit>
<Degree></Degree>
</Output>
</TemperatureConversion> |
FlowStart event :

Your flow backs out the message. That is why the flow starts twice.
You could add MQMD.BackoutCount in the event data so that the application that processes the events can ignore the second event. |

Hi Esa,
Thanks for responding,
I added the $Root/MQMD/BackoutCount for the flow start event and then deployed.
It is showing only two events i.e. flowrollback and flowend.
Transactionstart event is not coming...
Thanks....... |

OK, sorry.
I'm a bit rusty after several months break.
TransactionStart event is emitted before the message is parsed at all, so you cannot in fact add any message data in it. I think that is why you don't get the start events now, there is an exception while emitting them. |

Transaction Start event is in fact not very useful. In my opinion you only need it if you want to calculate the elapsed time for individual messages.
If you need to capture the message payload, you can do it with Transaction End and Transaction Rollback as well. |

Hi Esa,
Thanks for response,
Yes I want to capture the message but I want the three events in the output and I added the message data to the events but I didn't get the Transaction start event.
Thanks........ |
