This will create a public issue which anybody can view and comment on.

Please provide as much information as possible. At least, this should include a description of your issue and steps to reproduce the problem. If possible please provide a summary of what steps or workarounds you have already tried, and any docs or articles you found (un)helpful.

Problem you have encountered:
Currently, any user that kicks off a pipeline job won't be shown in Stackdriver logs. Instead it will show the Service Account which is being impersonated by the Pipeline job requester.

Thus, when customers need to extract the data to know who ran the job, they'll just see the Service Account in the principal email field which doesn't really help in tracking down which user ran the job.

What you expected to happen:
Requesting to add capability to track users who initiate AI Pipeline jobs (not the SA that it is impersonating) in Stackdriver Logs.
There should be a way to audit users running pipeline jobs.
