    Metadata details:
    filename: backpressure_monitor.rb
    path of file: ./repos/sentry-ruby/sentry-ruby/lib/sentry
    
    the code of the file until where you have to start completion: # frozen_string_litera
    
    def ensure_thread
      return if @exited
      return if @thread&.alive?

      @thread = Thread.new do
        loop do
          sleep(@interval)
          run
        end
      end
    rescue ThreadError
      log_debug("[BackpressureMonitor] Thread creation failed")
      @exited = true
    end
