Description

Currently, the JMX metrics exposed

metrics:name=drill.queries.completed
metrics:name=drill.queries.running
metrics:name=drill.queries.enqueued

The completed queries, however, do not distinguish between the outcomes of the completed queries.

The proposal is to also provide success, failed, cancelled and timeout (yet to implement) states.

  "metrics:name=drill.queries" : {
    "completed" : {
      "successful": INTEGER,
      "failed": INTEGER,
      "cancelled": INTEGER,
      "timeout": INTEGER
    },
    "running" : INTEGER,
    "enqueued" : {
      "small" : INTEGER,
      "large" : INTEGER
      }
    }
