metrics's Introduction

Metrics

Metrics 是一个暴露应用指标的平台，提供业务无侵入方式对生产级Java服务应用进行指标的监控和暴露。

🔥🔥🔥它提供多种指标的监控：

应用汇总
- 健康状态 ✅
- 应用启动时间 ✅
- JVM版本信息 ✅
CPU 情况 ✅
- CPU使用率 ✅
- CPU核数 ✅
- CPU负载 ✅
文件句柄情况 ✅
- 打开的文件句柄数 ✅
- 最大可打开的文件句柄数 ✅
类加载情况 ✅
- 已加载的类数量 ✅
- 未加载的类数量 ✅
Tomcat 运行情况 ✅
- Tomcat 线程池使用情况 ✅
- Tomcat 完成的任务数 ✅
JDK 线程池运行情况 ✅
- JDK 线程池使用情况 ✅
- JDK 线程池完成的任务数 ✅
内存区域占用情况 ✅
- 堆内存使用情况 ✅
GC 垃圾回收情况 ✅
独立线程池运行情况 ✅
- 运行中的线程数 ✅
- 守护线程数 ✅
- 线程状态分类汇总 ✅
- 单个线程运行情况 ✅
。。。

快速开始

Metrics 在所有主要操作系统上运行，只需要安装 Java JDK 版本 8 或更高版本。

$ java -version
java version "1.8.0_361"

使用 javaagent 的方式运行

可直接下载jar包
1. agent-1.0-SNAPSHOT.jar
2. core-1.0-SNAPSHOT.jar
或通过 maven package 对项目进行打包

把 agent 包放到自定义目录下，如：/tmp/agent-1.0-SNAPSHOT.jar

把 core 包放到同级的 lib 目录下，如：/tmp/lib/core-1.0-SNAPSHOT.jar

使用 -javaagent 命令启动

java -javaagent:/tmp/agent-1.0-SNAPSHOT.jar -jar demo.jar

MetricServer 会监听 http://127.0.0.1:12345/metrics ，确保该端口没有被本机其他人使用

也可通过命令指定监听的端口

java -javaagent:/tmp/agent-1.0-SNAPSHOT.jar=54321 -jar demo.jar

如果需要做监控大板，可参考 Grafana + Prometheus 方案

MetricHttpServer 线程

Describe the bug
MetricHttpServer 在新的线程中启动
业务线程启动失败的时候,JVM未退出

暂时不支持JDK17

JDk17运行会抛出异常
Exception in thread "MetricHttpServer" java.lang.NoClassDefFoundError: com/sun/net/httpserver/HttpServer
找不到类定义
