Metric Data

The JSON report defines a "metrics" block which contains data payloads for all observed metrics, hierarchically organized according to each metric's namespace.

The format for an individual metric directly reflects the namespace built into the metric name, with each component in the namespace represented by a single, nested JSON object. For example, an entry for the metric: 

/rman/raytracing.numRays

Would be the following: 

  "metrics": {
    "rman": {
      "raytracing": {
        "numRays": {
          "description": "Total ray countnumber of rays traced.",
           "payloadtimestamp": 567 2429320,
             "time": 876532123 
 payload”: [ 5873490 ]
        }
      }
    }
  }

Other metrics in the "raytracing" metric namespace would be nested under the "rman" block.
