You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: monitor.rb
    path of file: ./repos/test-prof/lib/test_prof/event_prof
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module TestProf
  module EventProf
    # Wrap methods with instrumentation
    module Monitor
      class BaseTracker
        attr_reader :event

        def initialize(event)
          @event = event
        end

        def track
          TestProf::EventProf.instrumenter.instrument(ev
    
        def call(mod, event, *mids, guard: nil, top_level: false)
          tracker = top_level ? TopLevelTracker.new(event) : BaseTracker.new(event)

          patch = Module.new do
            mids.each do |mid|
              if RUBY_VERSION >= "2.7.0"
                define_method(mid) do |*args, **kwargs, &block|
                  next super(*args, **kwargs, &block) unless guard.nil? || instance_exec(*args, **kwargs, &guard)
                  tracker.track { super(*args, **kwargs, &block) }
                end
              else
                define_method(mid) do |*args, &block|
                  next super(*args, &block) unless guard.nil? || instance_exec(*args, &guard)
                  tracker.track { super(*args, &block) }
                end
              end
            end
          end
