Deduplicate Metric Definitions #44
Description
The metric definitions are duplicated as many times as the metric is added in the JSON structure. Ideally the metrics definition need to be defined only once per metric. In the below example the metric definition for Items is added 4 times to the Metrics array.
Sample Kotlin Code
@JvmStatic
fun main(args: Array<String>) {
val metrics = MetricsLogger()
metrics.putDimensions(DimensionSet.of("Service", "Aggregator"))
metrics.putMetric("ProcessingLatency", 100.0, Unit.MILLISECONDS)
metrics.putMetric("Items", 1.0, Unit.COUNT)
metrics.putMetric("Items", 1.0, Unit.COUNT)
metrics.putMetric("Items", 1.0, Unit.COUNT)
metrics.putMetric("Items", 1.0, Unit.COUNT)
metrics.putProperty("RequestId", "422b1569-16f6-4a03-b8f0-fe3fd9b100f8")
metrics.flush()
}Output JSON
