Hi there, 
It'd be nice if we could send workflow stage information to logstash.

Possibly a step at the end of each run/ a joblistener that sends logstash events at the end.

1. Attaching to each stage, the node(s) that runs it,
2. Listing each stage's relationship to other stages.
3. Getting the stage's status, id, start time, build time, etc. 
4. List the branch that the stage is running on. 

Etc.
