I want to add some custom logs for tracking purposes so that i need to track job id for every execution of a channel.
(For example if channel is executing and let's say channel execution id or job id is 'QIE-123' and for each file transfer i am getting job instance id using qie.evaluateTemplate("{MSGID}") but here my question is how do i create or get channel execution id or job id in follwing channel.

in above channel i am hitting one rest end point and saving json response in file system.
script is as folloing
so with that script i also want to save job id or channel execution id.how to do that?
or else if i put my own custom job id then that job id will generate for every execution of script while i want i unique job id unless channel will not stop and restart again.
