How do I see which build slave a build ran on?

[Richard Cross]

Is there a way I can see a list of the build plan numbers, along with the build slaves eeach one ran on?  I'm trying to ascertain whether or not a seemingly random build failure is due to one build slave having a problem.

If you look at the build logs for your plan, at the top of the first stage it should show the agent used for example:

Build {ORG{ - {Build Project} - {Stage} {build#} {PlanKey} started building on agent {Agent_Name}
