16. !16 Elastic APM
17. !17 Full-stack monitoring with Elastic APM adds end-user experience and application-level monitoring to the stack
18. APM Architecture APM data is just another Index
19. !19 Supported agents - Python (https://github.com/elastic/apm-agent-python) - Node.js (https://github.com/elastic/apm-agent-nodejs) - Ruby (https://github.com/elastic/apm-agent-ruby) - JS Beta (https://github.com/elastic/apm-agent-js-base) - Go Beta (https://github.com/elastic/apm-agent-go) - Java Beta (https://github.com/elastic/apm-agent-java) All agents are Open Source and available on GitHub
20. !20 Java agent is now in beta!
21. !21 Download the agent • Download jar from Maven Central • Don't declare a dependency
22. !22 Start application with Java agent enabled java -javaagent:/path/to/elastic-apm-agent-<version>.jar \ -Delastic.apm.service_name=my-application \ -Delastic.apm.server_url=http://localhost:8200 \ -jar my-spring-boot-application.jar

25. !25 Supported Technologies • Java 7+ • Frameworks/APIs/Libraries ‒ Servlet API ‒ Spring Web MVC/Spring Boot ‒ JDBC • Application Servers/Servlet Containers ‒ Tomcat ‒ WildFly ‒ Jetty ‒ WebSphere ‒ Spring Boot with embedded Tomcat, Jetty and Undertow • Participate in the survey

29. How does it work? !29
30. !30 Instrumenting Servlets Request Response Agent Agent Servlet.s ervice • Java agents can modify classes when they are loaded • When Java load a Servlet class ‒ Agents adds code before and after Servlet#service ‒ Record Transactions (URL, parameters, response code) ‒ Send to APM Server
31. !31 Automatic + Manual Instrumentation • Automatically records requests ‒ HTTP traffic for Servlet API-based applications ‒ JDBC queries • Offers API for customization ‒ Application specific metadata ‒ Custom transactions ‒ OpenTracing integration The best of both worlds
32. Future? !32
33. !33 Future • Distributed Tracing ‒ Troubleshoot latency issues and errors in (micro-) service architectures ‒ Correlates the interaction of the services by passing correlation IDs • Better integration of APM/logging/metrics • Support for more frameworks and application servers ‒ Spring Web Reactive ‒ Tell us what you want support for: participate in the survey
