So CloudWatch announced a new “Embedded Metric Format” for high-cardinality logging: https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch_Embedded_Metric_Format.html — and I know that Lacinia is moving towards exposing some kind of logging too. I’d be interested in being able to bridge the two together, including things like timings etc. (Not that I’d expect Lacinia to output logs in that format, just to give building blocks so I could do it).

Not so much logging as some data about execution time.

With an eye towards identifying bottleneck in processing; things that should be made asynchronous.
