Is there a way to tell in concourse that what triggered a job?
If you’re running a new-ish version of Concourse the
get of the resource that triggered the job shows up in yellow. For example in this job new versions of
bbl-github-release triggered the build.
As far as system logging goes I don’t think this is captured though it might appear in audit logs if you have those enabled. See this related thread for more details.
