Java application outages can cost businesses thousands of dollars per minute. But what if those outages never happened? What if you could trace your code in real-time to identify errors prior to production?
Enter XRebel, a performance analysis tool that takes a proactive approach to Java performance analysis. Let’s dive into what XRebel is and why it’s a powerful addition to your Java tech stack.
What Is XRebel?
XRebel is a Java code analysis tool for development that delivers real-time performance insights.
With XRebel, developers can trace the impact of their code from beginning to end in distributed microservice-based applications. Java developers can then use the real-time Java performance metrics to identify, correct, and validate performance issues as they develop their application.
Unlike traditional performance tools, XRebel filters out irrelevant information, displays real-time metrics side-by-side with the application itself, and is easy to use for developers who may be less familiar with Java performance tools.
How Does XRebel Work?
XRebel is a JVM java agent -javaagent:/xrebel.jar, so you can run it on any server, anywhere. The XRebel toolbar is injected as an HTML widget in your application or in its own standalone window. There is no browser plugin necessary. XRebel works in any HTML5-compliant browser.
XRebel has a rich, intuitive UI that enables developers easily see performance metrics. With a request profiler, developers can also see the layers involved in the request and pinpoint where any bottlenecks are occurring.
XRebel can pick up NoSQL database queries, showing the actual query running against the database. The hierarchical view is designed to show as little as possible, even in huge applications, so you can see relevant information, including errors, faster.
What's New With XRebel
XRebel supports top frameworks, popular application servers, IDEs, NoSQL databases, and JVM languages. More importantly, XRebel works out of the box for almost every JVM-based stack.
The latest version of XRebel includes support for:
Java 8 through Java 24
Jetty 12 and older
Tomcat 11 and older
Spring Boot 3
Spring 6
Wildfly 34
Validate Code Changes in Real Time With XRebel
XRebel gives your developers real-time performance information alongside the application itself via an intuitive user interface. In-browser widgets provide real-time reports to help developers understand the performance impacts of code changes intuitively.
Best of all, XRebel doesn’t require in-depth experience with Java performance tools to generate real results.
Why Use XRebel?
XRebel is like “X-Ray goggles” for your Java applications—especially those built with a microservices architecture. With XRebel, developers are able to:
Improve performance. Follow a request across all XRebel-enabled services, seeing performance data for each.
Troubleshoot SQL and NoSQL IO. By increasing visibility into how JPA and Hibernate queries relate to JDBC invocations, XRebel makes suboptimal database issues easier to diagnose and fix.
Trace microservices. XRebel brings distributed tracing into the development environment, reducing microservice bottlenecks.
Debug easily. Sometimes distributed tracing, IO and performance metrics are not enough for your debugging needs. When that’s the case, XRebel shows logs and exceptions via the UI.
