metrics

Type Members

1. sealed trait MetricMessage extends AnyRef

   

   MetricMessage contains the data and metadata about a metric data point.

   MetricMessage contains the data and metadata about a metric data point.

   Each MetricMessage has the metric value itself and metadata about the type of com.codahale.metrics.Metric that it belongs to.

2. case class NotInitializedException(message: String, cause: Throwable) extends Exception with Product with Serializable

   

3. trait Sink extends metrics.sink.Sink

   

   Trait to expose Spark's org.apache.spark.metrics.sink.Sink trait, which is private to Spark

4. trait Source extends metrics.source.Source

   

   Trait to expose Spark's org.apache.spark.metrics.source.Source trait, which is private to Spark

5. case class SparkContextNotFoundException(message: String) extends Exception with Product with Serializable

   

6. class SparkCounter extends SparkMetric

   

   Acts like a com.codahale.metrics.Counter

7. class SparkGauge extends SparkMetric

   

   Acts like a com.codahale.metrics.Gauge.

   Acts like a com.codahale.metrics.Gauge.

   Unlike the Codahale version that requires an implementation of a getValue() method, this version implements a set method that just sets the value of this gauge.

8. class SparkHistogram extends SparkMetric

   

   Acts like a com.codahale.metrics.Histogram

9. class SparkMeter extends SparkMetric

   

   Acts like a com.codahale.metrics.Meter

10. sealed trait SparkMetric extends Metric with Serializable

    

    SparkMetric instances implement APIs that look like their Codahale counterparts, but do not store any state.

    SparkMetric instances implement APIs that look like their Codahale counterparts, but do not store any state. Instead, they just send the data points to the driver, where they are aggregated and published.
