      Description

      As the Spark Streaming tuning guide indicates, the key indicators of a healthy streaming job are:

      • Processing Time
      • Total Delay

      The Spark UI page for the Streaming job [1] shows these two indicators but the metrics source for Spark Streaming (StreamingSource.scala) [2] does not.

      Adding these metrics will allow external monitoring systems that consume the Spark metrics interface to track these two critical pieces of information on a streaming job performance.
