Java生产环境可观测性实战：JFR、GC与CPU故障诊断

面向高级Java工程师的线上排查实战课，无需Agent，利用JDK原生工具与OpenTelemetry、Micrometer，快速定位内存泄漏、线程死锁、CPU飙高与GC停顿等生产故障。

原始标题：Java Observability: Production JVM Diagnostics, JFR, GC, CPU

这是一门针对高级 Java 工程师的可观测性（Observability）与线上排查实战课程，主打**“无需安装任何 Agent 代理”**（No agents needed），教你利用 JDK 原生工具链和行业标准框架，快速定位并解决生产环境（Production）下的各类恶性故障。

• ⚡ 指标与链路监控：使用 OpenTelemetry SDK 和 Micrometer 对 Java SE 应用进行埋点，提取实时生产环境的遥测数据和度量指标。
• ⚡ 内存泄漏排查：捕获堆转储文件（Heap Dumps），并熟练使用 Eclipse MAT (Memory Analyzer Tool) 分析内存对象，精准定位复杂的生产环境内存泄漏。
• ⚡ 性能与锁分析：利用 JDK Flight Recorder (JFR) 和 JDK Mission Control (JMC) 动态分析在线应用的运行特征，排查线程锁竞争（Lock Contention）。
• ⚡ 系统稳定性诊断：诊断线程死锁（Deadlocks）、CPU 飙高（CPU Spikes）以及垃圾回收停顿（GC Pauses），从而稳定关键业务系统。

Master Java observability: thread dumps, heap analysis, JFR & GC logs to fix production incidents fast no agents needed.

What you’ll learn
⚡ Instrument Java SE apps with OpenTelemetry SDK and Micrometer to extract real-time production telemetry and metrics.
⚡ Capture and analyze heap dumps using Eclipse MAT to locate and resolve complex production memory leaks.
⚡ Profile live execution profiles and lock contention using JDK Flight Recorder and JDK Mission Control.
⚡ Diagnose thread deadlocks, CPU spikes, and garbage collection pauses to stabilize mission-critical Java systems.

Requirements
❗ ntermediate Java knowledge (Java 11+) and basic terminal usage. Standard JDK 17+ and JDK Mission Control (free) required.

Description

This course contains the use of artificial intelligence.
Debug, profile, and fix mission-critical Java applications directly in production environments with confidence.

Who this course is for

⭐ Senior Java developers, SREs, and architects responsible for troubleshooting memory leaks, crashes, and performance issues in production.
