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: gvl.rb
    path of file: ./repos/appsignal-ruby/lib/appsignal/probes
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
    
      def probe_global_timer
        monotonic_time_ns = @gvl_tools::GlobalTimer.monotonic_time
        gauge_delta :gvl_global_timer, monotonic_time_ns do |time_delta_ns|
          if time_delta_ns > 0
            time_delta_ms = time_delta_ns / 1_000_000
            set_gauge_with_hostname("gvl_global_timer", time_delta_ms)
          end
        end
