一个针对高并发、低延迟应用设计的高性能 Java 性能监控和统计工具。

GitHub (pre-)release Build Status Coverage Status GitHub issues GitHub closed issues GitHub

价值

  • 快速定位性能瓶颈
  • 快速定位故障原因

优势

  • 高性能: 单线程支持每秒 1600 万次 响应时间的记录,每次记录只花费 63 纳秒
  • 无侵入: 采用 JavaAgent 方式,对应用程序完全无侵入,无需修改应用代码
  • 低内存: 采用内存复用的方式,整个生命周期只产生极少的临时对象,不影响应用程序的 GC
  • 高实时: 支持秒级统计,最低统计粒度为 1 秒,并且是全量统计,不丢失任何一次记录

监控指标

MyPerf4J 为每个应用收集数十个监控指标,所有的监控指标都是实时采集和展现的。

下面是 MyPerf4J 目前支持的监控指标列表:

快速启动

MyPerf4J 采用 JavaAgent 配置方式,透明化接入应用,对应用代码完全没有侵入

下载

  • 下载并解压 MyPerf4J-ASM.zip
  • 阅读解压出的 README 文件
  • 修改解压出的 MyPerf4J.properties 配置文件中 app_namemetrics.log.xxxfilter.packages.include 的配置值

查看配置文件模板。想了解更多的配置?请看这里

配置

在 JVM 启动参数里加上以下两个参数

  • -javaagent:/path/to/MyPerf4J-ASM.jar
  • -DMyPerf4JPropFile=/path/to/MyPerf4J.properties

形如:java -javaagent:/path/to/MyPerf4J-ASM.jar -DMyPerf4JPropFile=/path/to/MyPerf4J.properties -jar yourApp.jar

运行

启动应用,监控日志输出到 /path/to/log/method_metrics.log:

卸载

在 JVM 启动参数中去掉以下两个参数,重启即可卸载此工具。

  • -javaagent:/path/to/MyPerf4J-ASM.jar
  • -DMyPerf4JPropFile=/path/to/MyPerf4J.properties

构建

您可以自行构建 MyPerf4J-ASM.jar

MyPerf4J-ASM-${MyPerf4J-version}.jar 在 MyPerf4J-ASM/target/ 目录下
