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

getOrCreateCounter(name, dimensions, publishingIntervalInSeconds) {
    validateCounterOptions(name, dimensions, publishingIntervalInSeconds);

    let counter;
    if (this._registry.hasMetric(name, dimensions)) {
      counter = this._registry.getMetric(name, dimensions);
    } else {
      counter = new Counter();
      const key = this._registry.putMetric(name, counter, dimensions);
      this._reporters.forEach(reporter => reporter.reportMetricOnInterval(key, publishingIntervalInSeconds));
    }

    return counter;
  }
