Please provide some insights to the Function Call Performance and Compilation Operation Performance sections

[iscb1962]

We've recently updated to version 2.3.0 which has provided new sections in the puppetserver grafana dashboard, specifically Compilation Operation Performance and Function Call Performance - however its not clear what these are showing and what would constitute an issue.

For example; each has a 'metric' at the bottom showing colours and various times - with the compile section in Compilation Operation(on one of our services) showing a 10s+ value for 5 minutes - is this an issue ? what would we need to investigate to find the issue ?

Its not clear if these tables are averages across the puppet servers (there are two in this service) or worst case.

Also we've noticed that the Function call perf section is showing figures for validate_hash and other functions that no longer exist (we updated stdlib approx 10 days ago, which removed this and other reported functions). Perhaps these are figures previously collected and will 'drop out' when the data expires. Please advise.
