# 进阶使用
## Web Console
通过 websocket 连接 Arthas。
- [Web Console](web-console.md)
## Arthas Properties
- [Arthas Properties](arthas-properties.md)
## 以 java agent 方式启动
- [以 java agent 方式启动](agent.md)
## 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
Arthas script version: 3.3.6

## 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。
