XRebel

 

Real-time performance metrics for local development

XRebel provides real-time feedback on application performance in local development to find and fix bugs faster.

 

Validate code changes in real time

The in-browser widget provides moment-by-moment developer-tailored reports to understand the performance impacts of code changes quickly and easily.

 

Made for developers

 

Only see the data you need, when you need it. XRebel cuts out the noise to help find and fix the biggest offenders in your code before they hit production.

 

 

Transactional

Follow requests through different threads, applications and JVMs.

Built for everybody

Useful for experts and junior developers alike.

Actionable data

Method-level drilldowns for pinpointing performance issues.

Rapid feedback

Continuous performance tuning for better code quality.

Features

 

1. The Standalone UI

 

Making Web Services development a first class experience.

 

The Standalone UI gives you ultimate visibility into your headless apps. Request details, IO activity, logs, exceptions and more are available right in the browser.

 

Eliminate bottlenecks

Drilldowns give you an overview of where the time is spent in each request

 

See all I/O activity

All database activity, messages, and jobs are shown in an expandable tree

 

Complete Visibility

Request details, logs, exceptions, and more are available in the browser

 

Inspect backend servers and web services

 

XRebel already has an outstanding support for web apps with a front end. And with ever popular web services architectures, we gave a facelift to our Standalone UI so that developers working on headless web services could enjoy a first class XRebel experience, too.

 

2. Understand App Performance

 

Make sense of the application structure and the layers involved in the execution.

 

It’s not about chasing milliseconds. XRebel reveals the most time-consuming methods in relation to the entire request.

 

3. Explore SQL and NoSQL IO

 

Find methods that pester your database too much.

 

Check your MongoDB, Cassandra, HBase and Neo4j queries. Get visibility into how JPA queries relate to the JDBC invocations. The full query is formatted for ultimate readability.

 

4. Get rid of web service bottlenecks

 

With a hierarchical overview of the executed HTTP invocations.

 

Inspect web service calls for REST, SOAP, XML-RPC and even plain old HttpURL Connection. Get notified when an application has slow HTTP requests, based on configurable thresholds.

 

5. Microservices and Single Page Apps

 

We care about the end-to-end experience.

Inspect distributed Java apps in a single view – even if you have a split frontend and backend.

 

6. Effortless debug logging

Get relevant information without digging through logs.

 

Logs appear in the XRebel toolbar with your requests. View logged objects in an expandable object tree. Works with arrays, collections and maps.

 

7. Track down hidden exceptions

 

The exceptions view reverses your stack traces to show buried exceptions.

 

Find the source of exceptions occurring anywhere from bad IO to outside of the application context.
