JVM性能调优监控工具jps、jstack、jmap、jhat、jstat、hprof使用详解 深藏阁楼爱情的钟 2022-08-10 03:57 214阅读 0赞 摘要 JDK本身提供了很多方便的JVM性能调优监控工具，除了集成式的VisualVM和jConsole外，还有jps、jstack、jmap、jhat、jstat、hprof等小巧的工具，本博客希望能起抛砖引玉之用，让大家能开始对JVM性能调优的常用工具有所了解。 现实企业级Java开发中，有时候我们会碰到下面这些问题： * OutOfMemoryError，内存不足 * 内存泄露 * 线程死锁 * 锁争用（Lock Contention） * Java进程消耗CPU过高 * ...... 这些问题在日常开发中可能被很多人忽视（比如有的人遇到上面的问题只是重启服务器或者调大内存，而不会深究问题根源），但能够理解并解决这些问题是Java程序员进阶的必备要求。本文将对一些常用的JVM性能调优监控工具进行介绍，希望能起抛砖引玉之用。本文参考了网上很多资料，难以一一列举，在此对这些资料的作者表示感谢！关于JVM性能调优相关的资料，请参考文末。 A、 jps(Java Virtual Machine Process Status Tool) jps主要用来输出JVM中运行的进程状态信息。语法格式如下： [?][Link 1] <table style="width:687px;
