Azure DevOps REST API - Get agent pools for jobs?

Question

I'm using the Azure DevOps REST API to retrieve pipeline runs (aka "builds"). The build response has a bunch of good data, but it seems that the pool it reports only applies if the overall pipeline has a top-level pool defined.

For example, I have a pipeline that runs several parallel jobs, each one in a different self-hosted agent pool. But when I retrieve a build of this pipeline using the REST API, the only data available is for the pipeline's pool, which is the normal Hosted Ubuntu 1604 response you get for Microsoft-hosted builds - there's no mention of any of the self-hosted agent pools that did all the work.

I've tried drilling down into different sections (including the stage and task queries). The task level will eventually show the name of the agent used, but it's just a string, so it's not easy to infer the agent pool used unless you happen to name your agents in a specific way.

Is there any way to drill down into the individual "jobs" that ran as part of a pipeline and see what agent pools they were run on, using the REST API?

Answer 1

The Build response contains a link timeline (under Links field).

You can form it like this: https://dev.azure.com/<org>/<project>/_apis/build/builds/<buildId>/Timeline

The Json response has useful info for each job/task including queueId

Answer 2

at present, our Rest API cannot help us drill down into the individual "jobs" that ran as part of a pipeline and see what agent pools they were run on. This Rest Api is used to find the default settings about your pipeline. As the work around, we can use the api: Builds - Get Build Log, and find the agent's name, like this:
