Hi Kunal,

did you use the same approach as with the other monitors by providing a services file at META-INF/services/org.eclipse.stardust.engine.core.spi.monitoring.IActivityInstanceMonitor with your implementation class in it?

Just checking before I try to reproduce it.

Thanks!

Hi,

We used the 'IActivityInstanceMonitor' instance and got some results. But we would like to ask for your help and guidance for clearing some of our doubts.

1. )

Is the method 'activityInstanceStateChanged' executing at the time of state change or after state change i.e the values that we get for various attributes as output are the vaules of the activity just before the change occurred OR are these values after the change has occurred ?


For e.g. We have a manual activity lets say 'InputClientDetails' and it goes through 4 state changes i.e Created-->Created , Created-->Suspended , Suspended-->Application, Application-->Completed.

And we can see that 'activityInstanceStateChanged' has also triggered 4 times displaying us the values of various attributes that we asked for in the code.
But in fact we feel its triggered before the activity change takes place and gives the Current state of activity, i.e. its current start time and other information.


Which means, we get 'Created' state 2 times, but Never get the 'Completed' state in the results!


2.) Continuation of 1.

How should we get all the attribute values for the 'Completed' activity (As we would like to find the total execution time of an Activity). We can see that the 'IProcessExecutionMonitor' can provide the 'LastModificationTime' of the activities in that process, once the process is completed.
But we would like to get the completion time of specific activities before the entire process gets completed?


We feel that the 'activityInstanceStateChanged' triggers only at a state change request and as 'Completed' is the Final state of any activity with no further change needed thus we do not get the details !

why is it important to us?
As in real world some processes may run for days, while some critical activities may run for a few minutes (using web servers).

Could you please help us by providing some insight on the above questions?

Thanks,
Kunal
