Usage

Clone and build the project then add the jar to your Maven or Gradle local repo (note: This is not available on Maven Central). Finally add the dependency to your Spring Boot project dependencies.

Maven:

<dependency>
    <group>org.springframework.boot</group>
    <artifactId>spring-boot-actuator-splunk</artifactId>
    <version>1.4.1.RELEASE</version>
</dependency>

Gradle:

compile ('org.springframework.boot:spring-boot-actuator-splunk:1.4.1.RELEASE')

If you are using a newer (or older) version of Spring Boot just modify the version in the build.gradle file and re-build.

Build

gradlew build

Configuration

Add the following to your Spring Boot application.properties file, or just make these available via System property.

# Port of the actuator endpoint
server.port=8080

# Time between polling the actuator endpoint
springboot.actuator.splunk.poll=30000

# The sourcetype for the log message that is sent to Splunk
springboot.actuator.splunk.sourcetype=myservice

# Destination HTTP url for sending events to Splunk
springboot.actuator.splunk.eventCollectorUrl=http://splunk:8090/services/collector/event

# Spring Boot management endpoint base context path
springboot.actuator.splunk.management.context-path=/manage

# Spring Boot management endpoints in which to poll (hint, you can add any endpoint, not limited to Spring Boot Actuator)
springboot.actuator.splunk.endpoints=health,metrics

# Splunk HTTP Event Collector authorization key
springboot.actuator.splunk.authorization=Splunk AA-BB-CC-DD

Troubleshooting

When the service starts you should see the following in the log Spring Boot Actuator Splunk enabled

If you application is not annotated with @SpringBootApplication then you will need to add @ComponentScan("com.springframework.boot.actuator.splunk").

@EnableAutoConfiguration
@ComponentScan("com.myapplication")
@ComponentScan("org.springframework.boot.actuator.splunk")
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Limitations

Currently this is in beta mode and only polls the Actuator endpoint using HTTP and no authentication.
