addSparseReactiveMetrics

addSparseReactiveMetrics(engine, metrics)

Adds sparse stateful computation metrics to the specified SparseReactiveStateEngine. The format of the new metrics is the same as the metrics parameter of createSparseReactiveStateEngine.

engine is a STRING scalar or an object, specifying the sparse reactive stateful engine to which computation metrics are added.

metrics is a table specifying the set of metrics to be added. Its schema is the same as the metrics parameter of createSparseReactiveStateEngine: keyColumn(s), formula, outputMetricKey.

Returns no value or returns an execution status (subject to the actual product implementation).

newMetrics = table(
    ["A003"] as deviceID,
    ["mavg(value,3)"] as formula,
    ["A003_1"] as outputMetricKey
)
addSparseReactiveMetrics("demoengine", newMetrics)
