如何使用监控诊断工具Arthas(阿尔萨斯)
2024-05-09 10:35:28
Arthas 是一款线上监控诊断产品，通过全局视角实时查看应用 load、内存、gc、线程的状态信息，并能在不修改应用代码的情况下，对业务问题进行诊断，包括查看方法调用的出入参、异常，监测方法执行耗时，类加载信息等，大大提升线上问题排查效率
目录
一、启动安装
二、能使用Arthas(阿尔萨斯做什么
1. 全局查看系统的运行状况
2. 查看指定线程堆栈信息
3. 排查为什么没有执行到修改的代码
4. 方法调用路径，以及性能分析
5. 线上 debug
一、启动安装
##1.下载
wget https://arthas.aliyun.com/arthas-boot.jar;##2.运行
java -jar arthas-boot.jar;例如： Windows上使用参考
1.执行java -jar arthas-boot.jar
D:\Soft\arthas-bin>java -jar arthas-boot.jar

二、能使用Arthas(阿尔萨斯）做什么
1. 全局查看系统的运行状况
dashboard 命令，查看当前系统实时数据面板
参数说明
-i : 指刷新的时间间隔
-n: 指刷新次数
例如：
[arthas@10668]$ dashboard

[arthas@10668]$说明
ID：Java级别的线程ID，注意这个ID不能跟jstack中的nativeID一一对应
NAME：线程名
GROUP：线程组名
PRIORITY：线程优先级, 1~10之间的数字，越大表示优先级越高
STATE：线程的状态
CPU%：线程消耗的cpu占比，采样100ms，将所有线程在这100ms内的cpu使用量求和，再算出每个线程的cpu使用占比。
TIME：线程运行总时间，数据格式为
- 分：秒
INTERRUPTED：线程当前的中断位状态
DAEMON：是否是daemon线程
2. 查看指定线程信息
Thread命令
参数说明
n：指定最忙的钱N个线程
b：找出当前是阻塞其他线程的线程
i ：指定CPU占比统计的采样时间，单位毫秒
例如 ：
thread 显示所有线程信息
thread 1 显示1号线程的运行堆栈
thread -b 查看阻塞的线程信息
thread -n 3 查看CPU使用率最高的3个线程
thread -i 1000 -n 3 ,每过1000秒采用，显示CPU使用最高的线程
#查看最耗CPU的两个线程

默认情况下arthas执行结果是不保存日志的，当然我们通过arthas提供的命令行options进行开启:
关闭日志打印
[arthas@10668]$ options save-result false NAME BEFORE-VALUE AFTER-VALUEsave-result true false开启日志打印 [arthas@10668]$ options save-result true NAME BEFORE-VALUE AFTER-VALUE
save-result false true[arthas@10668]$日志会异步保存在 {user.home}/logs/arthas-cache/result.log;
3.排查为什么没有执行到修改的代码
jad 命令
参数说明
- jad 包名.类名 反编译类
- jad包名.类名 方法名 只反编译某个方法
例如：
反编译com.star.sms.service.accept2.dto.NewInstallAcceptDTO如下。jad命令不仅可以查看到ClassLoader还能看到运行的Location信息。 这样可以很清楚了解到运行的是那个包下的类。类覆盖问题就变的很容易发现。
[arthas@10668]$

/*78*/ return this.rowNum;}public void setRowNum(int rowNum) {

如果类过大，反编译内容会很多，建议只反编译某个方法，例如

trace 命令： 方法内部调用路径，并输出方法路径上的每个节点上耗时
例如： 查看GwPaymentService#callFeePay 调用路径和耗时
[arthas@10668]$ trace com.star.sms.business.payment.gw.GwPaymentService callFeePay
Press Q or Ctrl+C to abort.
Affect(class count: 1 , method count: 1) cost in 184 ms, listenerId: 3

可以用正则表匹配路径上的多个类和函数，一定程度上达到多层 trace 的效果
例如： trace -E com.test.ClassA|org.test.ClassB method1|method2|method3
[arthas@13688]$ trace -E com.star.sms.business.provision.send.InstructionSender sendInstruction|sendGroupByGroup
Press Q or Ctrl+C to abort.

参数说明、
- params : 表示所有参数数组 （因为不确定是几个参数）
- returnObject:表示返回值
- -b 方法调用之前观察
- -e 方法异常后观察
- -s 方法返回后观察
- -f 方法结束后观察
- -x 属性深度
例如：
watch com.star.sms.business.payment.gw.GwPayService payOrder returnObj 观察返回值
watch com.star.sms.business.payment.gw.GwPayService payOrder params 观察输入参数
watch com.star.sms.business.payment.gw.GwPayService payOrder "{params, returnObj}" -x 3
[arthas@10668]$ watch com.star.sms.business.payment.gw.GwPayService payOrder returnObj
