Spring Boot Actuator exposes information about a running Spring Boot application via an http endpoint. Get useful diagnostics about an app programmatically using these RESTful APIs: health, git commit, build information, and so on. Now, developers can view some of this data in PCF Apps Manager. It’s easier to debug and monitor your apps in production, since Apps Manager shows this diagnostics info in context.
The steps are are described here BUT the steps below are more detailed and provide a sample application to verify this with.
http://docs.pivotal.io/pivotalcf/1-9/console/spring-boot-actuators.html
1. Add the maven dependency "spring-boot-starter-actuator" to your pom.xml
<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> </dependencies>
2. Ensure your using Spring Boot 1.5 snapshots/release candidates/final as earlier versions won't work.
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.0.BUILD-SNAPSHOT</version> <relativePath/> <!-- lookup parent from repository --> </parent>

3. Configure the Info Actuator as per link below
http://docs.pivotal.io/pivotalcf/1-9/console/spring-boot-actuators.html#info-endpoint
Note: It will differ depending on if your using Maven or Gradle
Ensure you add this property for GIT integration in your YML file or properties file, YML example
management:
info:
git:
mode: full
4. The following demo below has the required setup for verification application , clone and push to CF as shown below.
Note: review pom.xml for everything that is needed for this to work

$ git clone https://github.com/papicella/SpringBootPCFPas.git
$ mvn package
$ cf push -f manifest-inmemory-db.yml
