How to use the measured-core.NoOpMeter function in measured-core

getOrCreateTimer(name, dimensions, publishingIntervalInSeconds) {
    validateTimerOptions(name, dimensions, publishingIntervalInSeconds);

    let timer;
    if (this._registry.hasMetric(name, dimensions)) {
      timer = this._registry.getMetric(name, dimensions);
    } else {
      timer = new Timer({ meter: new NoOpMeter() });
      const key = this._registry.putMetric(name, timer, dimensions);
      this._reporters.forEach(reporter => reporter.reportMetricOnInterval(key, publishingIntervalInSeconds));
    }

    return timer;
  }

getOrCreateMeter(name, dimensions, publishingIntervalInSeconds) {
    this._log.error(
      'Meters will not get reported using the SignalFx reporter as they waste DPM, please use a counter instead'
    );
    return new NoOpMeter();
  }
