Scenario - I want to find out how long a web service call takes in OEG.
as you can see I have a Scripting filter before and after the WS call.
I test the policy via Service Explorer and view the trace afterwards.
You notice that the script includes a check for response time > 10 secs and sets the boolean response accordingly.
However, we may also want to get the actual response time as a process instance attribute. That is very easily done, just add the following to the 2nd script.
Firstly, define the output variable,
then add the following to the script itself -
You can see I have also added a Trace filter at the end of the process.
Deploy and test
