LanguageProject Introduction
Summary
This project is the primary way to get started with OpenTelemetry observability for Java applications, offering a zero-code-change agent for many frameworks and libraries, alongside an API for custom manual instrumentation.
Problem Solved
Collecting consistent and comprehensive telemetry data (traces, metrics, logs) from complex Java applications and microservices is challenging and often requires invasive code changes. This project simplifies the process significantly.
Core Features
Zero-code-change Agent
Automatically instruments popular libraries and frameworks without modifying application code.
Manual Instrumentation API
Provides libraries to add custom spans, metrics, and logs where auto-instrumentation is insufficient or specific business logic needs tracking.
Tech Stack
Java
JVM
OpenTelemetry API
OpenTelemetry SDK
Use Cases
This project is essential for any Java application where observability is critical, including:
Microservice Observability
Details
Trace requests across multiple services to understand distributed system behavior and identify bottlenecks.
User Value
Gain deep insights into inter-service communication and dependencies.
Application Performance Monitoring (APM)
Details
Collect metrics and traces for web applications, database calls, and external service interactions.
User Value
Pinpoint performance issues and optimize critical application paths.
