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
[INFO] arthas-boot version: 3.5.4
[INFO] Process 10668 already using port 3658
[INFO] Process 10668 already using port 8563
[INFO] Found existing java process, please choose one and input the serial number of the process, eg : 1. Then hit ENTER.
* [1]: 10668 org.jboss.Main
  [2]: 5952
  [3]: 2240

2.10668为需要监控的进程，是一个启动的Jboss服务，输入10668 前方的序号1回车，开始诊断监控，如下

[INFO] Process 10668 already using port 8563
[INFO] Found existing java process, please choose one and input the serial number of the process, eg : 1. Then hit ENTER.
* [1]: 10668 org.jboss.Main

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

 说明

  1. ID：Java级别的线程ID，注意这个ID不能跟jstack中的nativeID一一对应

  2. NAME：线程名

  3. GROUP：线程组名

  4. PRIORITY：线程优先级, 1~10之间的数字，越大表示优先级越高

  5. STATE：线程的状态

  6. 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。

  7. TIME：线程运行总时间，数据格式为

  8. 分：秒

  9. INTERRUPTED：线程当前的中断位状态

  10. 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

如果堆栈信息过大， 可以输出日志到文件

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-VALUE

save-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。

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

Affect(row-cnt:0) cost in 37 ms.

    +-org.eclipse.osgi.baseadaptor.BaseAdaptor$1@3983efa2

Location:
/E:/Jboss/jboss-4.2.3-8.2.1R1-8091-liaoning_821-5g/server/default/./deploy/stariboss.war/tmp/.patchtmp/1671784240888/a_780108_server_22112201_DB-9505.stariboss-customer.jar

        private Customer getCustomer(CustomerInfoDTO result, Long certificateTypeId, String certificateNum, SubscriberResultDTO subscriberResultDTO) {
            Customer customer = new Customer();
/*730*/     if (this.getCustomerCodeGenerator() == null) {
                throw new MsrRuntimeException("customer.code.is.required", false, false, null);
            }
/*731*/     this.getCustomerCodeGenerator().generateAndSetCustomerCode(customer);
/*736*/     customer.setName(result.getCUST_NAME());
/*748*/     customer.setCertificate(this.getCertificate(result, certificateTypeId, certificateNum));
/*752*/     customer.setContactAddress("");
/*753*/     customer.setContactTel(result.getCONT_NUMBER());
/*755*/     customer.setEnrolDate(new Date());
/*758*/     customer.setMobileTel(result.getCONT_NUMBER());
/*760*/     customer.setCustomerAddress("");
/*762*/     customer.setSaleChannel((SaleChannel)ApplicationSessionHolder.getApplicationSession().getValue("currentSaleChannel"));
/*765*/     Sex sex = Sex.getByCode((String)result.getGENDER());

/*785*/     customer.setDetailAddressCode("");
/*796*/     customer.setRemark("createByGwInfo,");
/*797*/     return customer;
        }

4.方法调用路径，以及性能分析

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

    `---[41.232898ms] com.star.sms.business.payment.gw.GwPaymentService:callFeePay()
        +---[0.020813ms] com.star.sms.business.payment.gw.helper.GwPaymentConverter:getInstance() #65
        +---[0.018817ms] com.star.sms.business.payment.gw.helper.GwPaymentConverter:callFeePayConvert() #65
        +---[0.019102ms] com.star.sms.gw.payment.GwPayDTO:getPayRecordId() #66
        `---[41.047583ms] com.star.sms.business.payment.gw.GwPaymentService:doPayFee() #66

trace 命令只会 trace 匹配到的函数里的子调用，并不会向下 trace 多层。因为 trace 是代价比较贵的

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.

watch命令检测函数入参返回值，抛出异常等信息

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
