Is it possible to get the pipeline ID from inside a Logstash config?
I have a monitoring script that gets the pipeline IDs from the Logstash API, and checks a file with the same name to see if the heartbeat is current.
Being able to use a variable for the filename would mean I can have the same output config for each pipeline, instead of manually naming each heartbeat file in a bunch of separate configs.
I've tried guessing a few variable names, but no luck.
