Simple integration between Grails and Elastic APM

Add dependency to apm-agent-api

Replace 1.12.0 with the current/required agent version.

dependencies {
    compile "co.elastic.apm:apm-agent-api:1.12.0"
}

Add Interceptor to application

Create an interceptor in grails-app/controllers, for example ApmInterceptor.groovy.

import co.elastic.apm.api.ElasticApm

class ApmInterceptor {

    ApmInterceptor() {
        matchAll()
    }

    boolean before() {
        ElasticApm.currentTransaction().setName(String.format("%s/%s", controllerName, actionName))
        true
    }

    boolean after() { true }

    void afterView() {
        // no-op
    }
}

Compile, package and run the application with agent

For example, when running application with ./gradlew bootRun, in build.gradle: Replace elastic agent jar path in build.gradle, and provide suitable Elastic APM server URL.

bootRun {
    jvmArgs = [
            "-javaagent:/path/to/elastic/agent/elastic-apm-agent-1.12.0.jar",
            "-Delastic.apm.server_url=http://localhost:8200",
            "-Delastic.apm.service_name=grails-app"
    ]
}

For other deployment options, refer to Elastic APM documentation.
