How do I find the Coin builds that are running in "subtle-iguana" or other hosts?

So today people are reporting to me that builds have timed out and things are generally very slow. One of my builds that timed out was in "subtle-iguana". I want to:

• Check the other builds that have just finished on that host, see the coin log; did they time out too?
• Check the builds that are currently running, see the coin log; are they going unusually slow?

Additionally I want to know if my changes on "ace-fawn" and "apt-bee" (bigger swap file and set swappiness to zero) have a positive or negative effect to the builds.

So it is very important to be able to go from the ONE id (one-12345) to the Coin build. Is it possible? If not, any ideas to achieve it in the future?
