This week Amos is back from his yearly vision quest and Chris faces the problem of being interested in too many things at once. Amos discusses some experiences using Broadway and GenStage which gives Chris an excuse to bring up Little’s Law (as if he needed one).

The main topic this week is observability. This topic is motivated by Amos’s latest book: Behind Human Error. Amos provides a brief rundown and Chris talks with authority about things he really doesn't understand. The guys discuss the importance of setting goals for your services and how those goals will inform your metrics gathering and alerting strategies. The show wraps up with some tips on benchmarking and profiling.
