Title: Message Title Charlie Sharpsteen commented on PUP-7520 Re: Puppet profiling timers do not use a monotonic clock Re-opening this one as inaccurate profiling results are far, far worse than not having any profiler functionality. This condition is uncommon, but Puppet does manage the sort of system configuration that can cause clock jumps. This change probably doesn't even need to wait for a semver major like Puppet 8 at this point as Ruby 2.1 and older are deeply end of life.

Title: Message Title
Charlie Sharpsteen updated an issue
Puppet / PUP-7520
Puppet profiling timers do not use a monotonic clock
Change By:
Charlie Sharpsteen
Puppet has support for timing and profiling execution through the {{Puppet::Util::Profiler::WallClock}} class, used for profiling Puppet Server operations, and the {{Puppet::Util.thinmark}} method, used for measuring things like resource application. Historically these methods have measured time by calling {{Time.now}}. However, this method returns a value from the OS REALTIME clock, which can be affected by events like NTP updates. Since the puppet agent often initiates a NTP update, these jumps can create confusing profile resullts results .In 2.1.0, Ruby added methods to access a monotonic clock which isn't affected by things like NTP updates. We should prefer this clock for profiling timers when it is available:https://ruby-doc.org/core-2.1.0/Process.html
