My team has been happily implementing CI for the last couple months with TeamCity. I particularly like the statistics tab (which I'm not sure existed the last time I used TeamCity). I noticed that there is a "time to fix failed tests" chart, but is there any way to track the time to fix failed builds? It seems like it would be useful to track the total amount of time your build is in a failed state for any reason (whether a compiler error, a TC configuration problem, or a test).
Assuming this functionality isn't already implemented in TC (and hiding somewhere), could I produce this kind of chart with a custom chart or would it probably take a plugin?
