# Stream Apps Monitoring
|
|
|
|
Add `org.springframework.cloud:spring-cloud-stream` and `org.springframework.cloud:spring-cloud-starter-stream-rabbit` to your Spring Boot application
|
|
POM to turn it into Stream Cloud Stream Application:
|
|
|
|
```xml
|
|
<dependency>
|
|
<groupId>org.springframework.cloud</groupId>
|
|
<artifactId>spring-cloud-stream</artifactId>
|
|
</dependency>
|
|
|
|
<dependency>
|
|
<groupId>org.springframework.cloud</groupId>
|
|
<artifactId>spring-cloud-starter-stream-rabbit</artifactId>
|
|
</dependency>
|
|
```
|
|
|
|
To replace Rabbit by Kafka binder use the `org.springframework.cloud:spring-cloud-starter-stream-kafka` dependency instead instead.
|
|
|
|
To enable SCDF Prometheus Proxy monitoring for your application you would need to add the following additional additional dependencies:
|
|
|
|
```xml
|
|
<dependency>
|
|
<groupId>org.springframework.cloud.stream.app</groupId>
|
|
<artifactId>app-starters-micrometer-common</artifactId>
|
|
<version>2.1.2.RELEASE</version>
|
|
</dependency>
|
|
<dependency>
|
|
<groupId>io.micrometer</groupId>
|
|
<artifactId>micrometer-registry-prometheus</artifactId>
|
|
</dependency>
|
|
<dependency>
|
|
<groupId>io.micrometer.prometheus</groupId>
|
|
<artifactId>prometheus-rsocket-spring</artifactId>
|
|
<version>0.9.0</version>
|
|
</dependency>
|
|
```
|
|
|
|
The `micrometer-registry-prometheus` amd `prometheus-rsocket-spring` activate the Micrometer Prometheus support for RSocket Proxy meter registry.
|
|
The `app-starters-micrometer-common` would inject some common metrics Tags such as `stream.name`, `stream.app.label`, `application.type` and `application.guid`.
|
|
Later are used in the SCDF Grafna Dashboards to visualize the Stream Application rates, throughput and so on.
