I plan to collect statistics on build queue and resource wait times across the build infrastructure to evaluate whether we need to scale up our build agents. Is there a way to get wait time of each build or each configuration? Any suggestion is appreciated.

I believe I can calculate the wait time as follow:
waitTime = startDate - requestDate
wait time = startDate - scheduleDate

Looks like requestDate/scheduleDate is purged after build is completed.

There is a build wait duration. We will add stats for this metric in QB16.

Thank you for promptly responding, Robin!
The metric will be very helpful, and I look forward to seeing it.
I am getting the startDate, endDate, and requestDate as follow:
   reqObj = build.getRequest()
   requestDate = reqObj?.getRequestDate()
   startDate = build.getBeginDate()
   endDate = build.getEndDate()

  However, requestDate is purged after the build is completed. How do I obtain the wait duration (as you mentioned) of a completed build? Please advise.
