Possible to instrument ViewComponent renders with Sentry traces?

[cannikin]

I'd like to instrument my ViewComponents with Sentry Traces so I know how long things are taking. Sentry hooks into the stock Rails stuff amazingly well, and you can add your own custom timing entries. The Sentry docs have you surround your code in a Sentry.with_child_span block and they take care of the rest. I've done this with some other API call stuff and it works great (request.operator in the example below are my custom ones):

I've got an ApplicationComponent that's the parent class of all of my components, which would be an ideal place to put it. But, I've only seen a before_render lifecycle hook. Is there a secret undocumented around_render hook maybe? Or another technique I can use to implement this tracing, without surrounding every single component render with that block in every view.

The first syntax I came up with off the top of my head was something like:

class ApplicationComponent < ViewComponent::Base
  around_render :trace

  def trace
    Sentry.with_child_span op: "render.view_component", description: self.class.name do |span|
      yield
      span.set_data("metadata", foo: "bar")
    end
  end
end
