English:

• Based on the Arthas command generation plugin developed by IntelliJ IDEA, it supports Alibaba Arthas official commonly used commands. • The official commands are too complicated. In order to simplify the difficulty of users, this plugin provides support for some common commands. • The plugin supports Alibaba Arthas commands such as watch、trace、ognl static、ognl bean method、field、monitor、stack 、tt etc. • watch: Display the input/output parameter, return object, and thrown exception of specified method invocation • trace: Trace the execution time of specified method invocation. • ognl:Execute ognl expression. • monitor:Monitor method execution statistics, e.g. total/success/failure count, average rt, fail rate, etc. • stack:Display the stack trace for the specified class and method • tt:Time Tunnel • support get all spring property command、get selected spring property • logger:Print logger info, and update the logger level • Async Profiler. https://github.com/jvm-profiling-tools/async-profiler

中文：

• 基于IntelliJ IDEA开发的Alibaba Arthas 命令生成插件，支持Alibaba Arthas 官方常用的命令。 • 官方的命令太复杂，此插件为了简化使用者的难度，提供了一些常用命令的支持 • 该插件支持Alibaba Arthas 常用命令,比如 watch、trace、ognl static、ognl bean method、field、monitor、stack 、tt等命令 • 支持设置static field、static final • watch:能方便的观察到指定方法的调用情况,返回值、抛出异常、入参(特殊值、异常没有捕获排查)

•

• trace:方法内部调用路径，并输出方法路径上的每个节点上耗时(性能问题，调用链问题)

•

• ognl:执行表达式(方便获取静态变量，方法，获取spring context 为所欲为) • monitor:方法执行监控(性能问题排查，一段时间内的性能指标) • stack:获取方法从哪里执行的调用栈(用途：源码学习调用堆栈，了解调用流程) • tt:方法执行数据的时空隧道，记录下指定方法每次调用的入参和返回信息，并能对这些不同的时间下调用进行观测(可以重新触发，周期触发，唯一缺点对于ThreadLocal 信息丢失[隐含参数]、引用对象数据变更无效) • 支持获取选择中的spring 环境变量的值获取，获取spring 上下文所有的环境变量按照优先级打印出来,方便排查环境问题 • logger:动态更新日志等级 • Async Profiler. https://github.com/jvm-profiling-tools/async-profiler 火焰图命令支持
