6. Elastic APM Java Agent is Generally Available

Elastic APM Java Agent is Generally Available


  • We are thrilled to announce that our Java Agent is now generally available (GA)! After a successful beta phase, with lots of downloads and plenty of feedback, we are ready to release the production-ready version, 1.0. Note that this version requires at least APM Server 6.5.

    The Java agent is the new member of the Elastic APM agent family, joining Node.js, Python, Ruby, JavaScript/RUM, and Go (a new GA sibling as well). Elastic APM is the Application Performance Monitoring solution from Elastic that helps you to gain insight into the performance of your application and track errors.

    Main Features

    What you get out of the box

    Installing the Elastic APM Java agent is as simple as adding the -javaagent flag and a couple of system properties to your JVM startup command. As long as you are using supported frameworks and platforms, such as Spring MVC/Spring Boot, Servlet API, and JAX-RS, your application will be instrumented and monitored automatically.

    Web Request Visibility

    Get a high-level overview of your Java applications, and drill down to see how your Servlets or Spring Controllers are doing individually:

    Data Store Visibility

    Using JDBC or Elasticsearch? Learn where your Java application spends time on DB calls, which queries take longest and find out what errors they produce. You might be surprised what kind of queries your ORM mapper generates!

    Networking Visibility

    The Java agent also records how long your application is spending on external HTTP calls, so you can tell how much time is spent waiting for services out of your control.

    Distributed Tracing

    If your Java application is just one component in a multi-service setup, your traces will include data collected from any caller and callee that have an APM agent installed on them as well. As long as you are using one of the supported networking frameworks, the agent makes sure that it passes correlation IDs along so that you can see which services are involved in serving a request and which one is to blame when the request was slow. You can read more about distributed tracing in the Elastic APM 6.5.0 release announcement.

    Enrich and Extend

    For anything you want and don’t get out of the box

    Is your Java application not using any of the supported technologies? Do you want better visibility to specific parts of your internal code? No worries, we provide the infrastructure that can help you trace virtually anything.

    Customize your APM solution using our API

    You can trace any method you wish using our public API. This API lets you customize and manually create spans and transactions, as well as track errors.

    For example, our annotations API can be used as follows: 

    import co.elastic.apm.api.CaptureSpan;
import co.elastic.apm.api.ElasticApm;
import co.elastic.apm.api.Span;

public class MyImportantBusinessLogic {
    
    @CaptureSpan("Main-business-logic")
    public void myVeryImportantMethod(String someInfo) {
        ElasticApm.currentSpan().addTag("info", someInfo);
        // My important logic comes here
    }
}
