Problem
When following the setup laid out in the Readme and using the example initializer I only get entries for classes specified in config.classes_to_monitor, not their subclasses (i.e. ActiveRecord::Base but no models)
This appears to be due to the fact that at the time the initializer is run, Rails has not yet loaded all the classes.
I have tried this on 4.2, 5.2, and 6.0.0.rc1 all with the same results.
It is easy to verify by opening a rails console and running:
ObjectSpace.each_object(ActiveRecord::Base.singleton_class).count
On all 3 apps I get 1, because the models are not yet loaded.
Fix
I am able to get things working as expected by adding:
Rails.application.eager_load! to the top of the initializer.
This is ok, but I wanted to sanity-check if this is expected or if I should be doing something different with the initializer/config.
Happy to put in a PR against the Readme if this fix is the "right way™️" of doing things.
As an aside - Thanks for making this public, it's a very nifty use of Ruby's flexibility. Saw it mentioned in a Railsconf talk and eager to try it out in production.
