Suggestions for High Level System Monitoring

Hi, I'm looking for a generic way to be notified when an exception happens in the system. We had a periodic system task fail last week, and we didn't find out until one of our users told us about it. I'd like to be notified before they notice. I've seen there are ways to use BPMNErrors, but I'm

Do you mean that one of the service tasks was failing? If this service task is a job you could use the event handlers of the Activiti Engine (http://activiti.org/userguide/index.html#eventDispatcher) to listen to JOB_EXECUTION_FAILURE events. It's also possible to throw a BpmnError from a service task and listen to the UNCAUGHT_BPMN_ERROR event without needing to add catching error event elements in the process definition. Is this what you are looking for?

Best regards,

Can you tell me when UNCAUGHT_BPMN_ERROR is really thrown and how to catch it?

I've created a ActivtiEventListener that I have registered in the ProcessEngine. It receive a lot of events, but I wasn't able to get the UNCAUGHT_BPMN_ERROR event. It instead log a "BpmnError: No catching boundary event found for error with errorCode" message and freeze there. My test never finish.

I may have do something wrong, just searching for an example somewhere and I've done a globak search for : UNCAUGHT_BPMN_ERROR and found nothing…

If it's really important you cause that execution flow, I'd suggest looking through the code on github; that's what I did. I was happy with the testing I was able to achieve with unit tests, and that I covered all "bad" sounding events was good enough for our scenario.

Sorry I can't be of more assistance!
