Would it be possible to write a fuller description to the issue? This is a non-trivial change to our code and we need to be able to release note it.

@pjfanning I can add more to the issue. But I’d consider this a rather trivial change.

There is no functional difference, the implementation is now open for Kanela to intercept the call to the new method to report that metric to Kamon. Or to extend this class and overwrite the method to get the interval.

Also the new trait makes it possible to implement a custom failure detector with the same functionality.
This isn’t really needed for our case, but we find it good design to not match on a specific implementation when that one is replaceable by design.

lgtm, as far as I can tell this is just shuffling code around so certain parts of it can be overridden (i.e. enabling features like monitoring interval).

If the usercase is for aop,then we should better have javadsl in mind too.

The use case would be to intercept or override the call to recordInterval
