= Analytics Sink
Meter that compute multiple metrics from the received messages. It leverages the Micrometer library and can use various popular TSDB to persist the meter values.
By default the Analytics Sink increments the `message`.`name` meter on every received message.
If tag expressions are provided (via the `analytics.tag.expression.<tagKey>=<tagValue SpEL expression> property) then the `name` meter is incremented. Note that each SpEL expression can evaluate into multiple values resulting into multiple meter increments (one fore every value resolved).
If fixed tags are provided they are include in all message and expression meter increment measurements.
Analytics's implementation is based on the https://micrometer.io/[Micrometer library] which is a Vendor-neutral application metrics facade that supports the most popular monitoring systems.
See the https://micrometer.io/docs[Micrometer documentation] for the list of supported monitoring systems. Starting with Spring Boot 2.0, Micrometer is the instrumentation library powering the delivery of application metrics from Spring Boot.
All Spring Cloud Stream App Starters are configured to support two of the most popular monitoring systems, Prometheus and InfluxDB. You can declaratively select which monitoring system to use.
If you are not using Prometheus or InfluxDB, you can customise the App starters to use a different monitoring system as well as include your preferred micrometer monitoring system library in your own custom applications.
https://grafana.com/[Grafana] is a popular platform for building visualization dashboards.
To enable Micrometer’s Prometheus meter registry for Spring Cloud Stream application starters, set the following properties.
```
management.metrics.export.prometheus.enabled=true
management.endpoints.web.exposure.include=prometheus
```
and disable the application’s security which allows for a simple Prometheus configuration to scrape meter information by setting the following property.
```
spring.cloud.streamapp.security.enabled=false
```
To enable Micrometer’s Influx meter registry for Spring Cloud Stream application starters, set the following property.
```
management.metrics.export.influx.enabled=true
management.metrics.export.influx.uri={influxdb-server-url}
```
NOTE: if the https://docs.spring.io/spring-cloud-dataflow/docs/2.0.0.BUILD-SNAPSHOT/reference/htmlsingle/#streams-monitoring[Data Flow Server metrics] is enabled then the `Analytics` will reuse the exiting configurations.
Following diagram illustrates Analytics' information collection and processing flow.

= Counter Sink
Counter that compute multiple counters from the received messages. It leverages the Micrometer library and can use various popular TSDB to persist the counter values.
By default the Counter Sink increments the `message`.`name` counter on every received message. The `message-counter-enabled` allows you to disable this counter when required.
If tag expressions are provided (via the `counter.tag.expression.<tagKey>=<tagValue SpEL expression> property) then the `name` counter is incremented. Note that each SpEL expression can evaluate into multiple values resulting into multiple counter increments (one fore every value resolved).
If fixed tags are provided they are include in all message and expression counter increment measurements.
Counter's implementation is based on the https://micrometer.io/[Micrometer library] which is a Vendor-neutral application metrics facade that supports the most popular monitoring systems.
See the https://micrometer.io/docs[Micrometer documentation] for the list of supported monitoring systems. Starting with Spring Boot 2.0, Micrometer is the instrumentation library powering the delivery of application metrics from Spring Boot.

# Counter Consumer
# Analytics Consumer
The `counter-consumer` is a Java https://docs.oracle.com/javase/8/docs/api/java/util/function/Consumer.html[Consumer<Message<?>>] that computes analytics from the input data messages and publishes them as metrics to various monitoring systems.
The `analytics-consumer` is a Java https://docs.oracle.com/javase/8/docs/api/java/util/function/Consumer.html[Consumer<Message<?>>] that computes analytics from the input data messages and publishes them as metrics to various monitoring systems.
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 counter-consumer can produce two metrics types:
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.
