Hi,
Please help, I need to create a subflow that would be used for logging. I need to pick up the mainflow that contains the subflow and the node which called the subflow. This is the only way that I can think of dynamic way to figure out which logging event is to be logged.
I am not sure if the design is possible(realistic)  , but I wanted to do as dynamic as possible. |

| IMO, isn't that more reasonable to determine which event to log based on the what message comes into the subflow, instead of based on which node/main flow calls the subflow? |

There's a whole bunch of message flow and node properties you can access. See the Broker Properties section in the ESQL Reference. But if you want to access a previous node's properties after the flow has entered the subflow, I think you'll need to pass them in the environment or local environment.

Thanks for the response. I am trying to send the event to be logged, but I am a bit relactant to put a compute node infront of every note that needs to send and event, SO I was hoping to find a simple generic way to have one subflow that can do it.
Is there any otherway to send out event message to a queue, without actually writing ESQL code to hardcode the event after every node?  |

Yes, MB version 7 supports Common Event Infrastucture. You can just configure a node to emit events. The events are published to system topics. If you want to use CEI, you are actually supposed to buy WebSphere Business Monitor, which is as far as I know much more expensive than Message Broker. But you can as well subscribe to those topics, examine the messages and write you own monitoring application. I am not saying that it will be easy, but that is what I would try if I were you.
Take a look at
