## 以 java agent 方式启动

## as.sh 和 arthas-boot 技巧
|
|
|
|
|
|
|
|
|
|
|
|
- 通过`select`功能选择 attach 的进程。
|
|
|
|
|
|
|
|
|
|
|
|
正常情况下，每次执行`as.sh`/`arthas-boot.jar`需要选择，或者指定 PID。这样会比较麻烦，因为每次启动应用，它的 PID 会变化。
|
|
|
|
|
|
|
|
|
|
|
|
比如，已经启动了`math-game.jar`，使用`jps`命令查看：
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
$ jps
|
|
|
|
|
|
58883 math-game.jar
|
|
|
|
|
|
58884 Jps
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
通过`select`参数可以指定进程名字，非常方便。
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
$ ./as.sh --select math-game
|
|
|
|

## 用户数据回报
|
|
|
|
|
|
|
|
|
|
|
|
在`3.1.4`版本后，增加了用户数据回报功能，方便统一做安全或者历史数据统计。
|
|
|
|
|
|
|
|
|
|
|
|
在启动时，指定`stat-url`，就会回报执行的每一行命令，比如： `./as.sh --stat-url 'http://192.168.10.11:8080/api/stat'`
|
|
|
|
|
|
|
|
|
|
|
|
在 tunnel server 里有一个示例的回报代码，用户可以自己在服务器上实现。
