We need to be able to compare and discover ansible performance regressions or improvements of ansible. Currently we have no way of detecting changes there other than observing the overall system load of executors. One way to get some metrics is to log the cpu times used by individual ansible runs and the sum of them over the whole job execution. With this one could grab that data from the log and analyse them.
