Completed process: how to visualize and show variables

imbaczek

I've got a process that doesn't have any human tasks. I'd like to see its variables and execution path just as if I was looking at a running process (for debugging and monitoring). Is this possible? Sounds like an obvious use case, I just hope its hidden too well for me to find it. Having the option of extracting this information using REST would be also very nice.

The value in {} bracket is variable value when process execution left the node. It means that process started with x=0, after the first step x= x+1 => x had value 1. User changed x value to 3.

Image displayed is audit trail (only path for this process instance is displayed) . Complete process definition is
