Abstract Value Members

  1. abstract def counter(name: MetricName, description: String = "")(implicit context: MetricsContext = MetricsContext.Empty): Counter

    A counter represents a value that can go up and down.

    A counter represents a value that can go up and down. For both Dropwizard and OpenTelemetry a counter is actually represented as a gauge. We can think of a counter as a gauge with a richer API.

  2. abstract def gauge[T](name: MetricName, initial: T, description: String = "")(implicit context: MetricsContext): Gauge[T]

    A gauge represents the current value being monitored, such as queue size, requests in flight, etc.

    A gauge represents the current value being monitored, such as queue size, requests in flight, etc. The values being monitored should be numeric for compatibility with multiple metric systems (e.g. Prometheus).

  3. abstract def gaugeWithSupplier[T](name: MetricName, gaugeSupplier: () => T, description: String = "")(implicit context: MetricsContext): CloseableGauge

    Same as a gauge, but the value is read using the gaugeSupplier only when the metrics are observed.

  4. abstract def histogram(name: MetricName, description: String = "")(implicit context: MetricsContext = MetricsContext.Empty): Histogram

    A histogram represents a bucketized view of the data.

    A histogram represents a bucketized view of the data. In most cases the boundaries of the buckets should be manually configured for the monitored data.

  5. abstract def meter(name: MetricName, description: String = "")(implicit context: MetricsContext = MetricsContext.Empty): Meter

    A meter represents a monotonically increasing value.

    A meter represents a monotonically increasing value. In Prometheus this is actually represented by a Counter. Note that meters should never decrease as the data is then skewed and unusable!

    MetricsFactory
  6. abstract def timer(name: MetricName, description: String = "")(implicit context: MetricsContext = MetricsContext.Empty): Timer

    A timer can be represented by either a summary or a histogram.

    A timer can be represented by either a summary or a histogram.

    • For Dropwizard the timer is represented as a summary.
    • For OpenTelemetry the timer is represented by a histogram.
