@drewverlee: I haven’t heard of Xtracing. Got any links you could point me at? (resorting to Google now 😉)
@avey_q: here is the paper from google that i suppose a lot of people refer to on this subject: https://static.googleusercontent.com/media/research.google.com/en//pubs/archive/36356.pdf here is a talk: https://www.youtube.com/watch?v=ya9X63VPgV8 here is a summery of it: https://blog.acolyer.org/2015/10/06/dapper-a-large-scale-distributed-systems-tracing-infrastructure/ I haven’t gotten around to reading the paper yet all the way trough yet, but the video & summery does a good job of pulling things together.
