Arthas Properties
===
`arthas.properties`文件在arthas的目录下。
* 如果是自动下载的arthas, 则目录在`~/.arthas/lib/3.x.x/arthas/`下面
* 如果是下载的完整包, 在arthas解压目录下
## 支持的配置项
```
#arthas.config.overrideAll=true
arthas.telnetPort=3658
arthas.httpPort=8563
arthas.ip=localhost
#arthas.tunnelServer=ws://127.0.0.1:7777/ws
#arthas.agentId=mmmmmmyiddddd
```
* 如果配置 `arthas.telnetPort`为 -1 , 则不listen telnet端口。`arthas.httpPort`类似。
* 如果配置 `arthas.telnetPort`为 0 , 则随机telnet端口, 在`~/logs/arthas/arthas.log`里可以找到具体端口日志。`arthas.httpPort`类似。
> 如果是防止一个机器上启动多个 arthas端口冲突。可以配置为随机端口, 或者配置为 -1, 并且通过tunnel server来使用arthas。
## 配置的优先级
配置的优先级是:命令行参数 > System Env > System Properties > arthas.properties 。
比如:
* `./as.sh --telnet-port 9999` 传入的配置会覆盖掉`arthas.properties`里的默认值`arthas.telnetPort=3658`。
* 如果应用自身设置了 system properties `arthas.telnetPort=8888`,则会覆盖掉`arthas.properties`里的默认值`arthas.telnetPort=3658`。
如果想要 `arthas.properties`的优先级最高,则可以配置 `arthas.config.overrideAll=true` 。
