The metrics track payload format is defined in [MOQMETRICS]. The data model consists of Resources (systems generating metrics identified by ResourceID), optional Attributes (dimensional key-value pairs), and Metrics (named measurements with timeseries values).
[MOQMETRICS] defines two metric value types - Gauge and Counter. Both value types support either 64-bit floating point or integer representation. Implementations MUST follow the object payload format specified in Section 3 of [MOQMETRICS].
