https://s.natalian.org/2018-04-19/latency.mp4 just cared to monitor TargetResponseTime.

Using Aurora should allows us to plot metrics of queries taking a long time. I am assuming this is the cause of long TargetResponseTimes reported by the ECS load balancer on Bugzilla.

Then we can hopefully drill down the troublesome queries.

Hopefully an see the slow queries with select sleep(10);.

From my investigations here: https://github.com/unee-t/whyslow

It would appear AuroraDB is not slow. There is some bottle neck in process_bug.cgi in the Bugzilla side.
