Finding which pipeline and worker touched an event

Does Stream attach the worker ID to each event in the internal fields like cribl_pipe does for the pipelines? If so, what is the field name? If not, is there a way to make stream add the worker ID to the event?

If you’re looking for the name of the worker node which processed the event, you can add a field whose value is: C.os.hostname()

You can select what System fields you would like by going to any Destination → Post-Processing → and add the fields you would like under System Fields.
