|
||||
It leverages the https://micrometer.io[micrometer library] for providing a uniform programming experience across the most popular https://micrometer.io/docs[monitoring systems] and uses https://docs.spring.io/spring-integration/reference/html/spel.html#spel[Spring Expression Language (SpEL)] for defining how the metric names, values and tags are computed from the input data.

The analytics-consumer can produce two metrics types:

- https://micrometer.io/docs/concepts#_counters[Counter] - reports a single metric, a count, that increments by a fixed, positive amount. Counters can be used for computing the rates of how the data changes in time.
|
||||
- https://micrometer.io/docs/concepts#_gauges[Gauge] - reports the current value. Typical examples for gauges would be the size of a collection or map or number of threads in a running state.
