Arthas supports the Web Console. After attach success, the user can access: [http://127.0.0.1:8563/](http://127.0.0.1:8563/).
|
||||
|
||||
The user can fill in the IP and connect the remote arthas on other machines.
|
||||
|
||||
|
||||
|
||||
|
||||
> By default, arthas only listens to `127.0.0.1`, so if you want to connect from a remote, you can use the `--target-ip` parameter to specify the IP. See the help description for `-h` for more information.
|
||||
|
||||
If you have suggestions for the Web Console, please leave a message here: [https://github.com/alibaba/arthas/issues/15](https://github.com/alibaba/arthas/issues/15)

### Connect remote arthas through arthas tunnel server
|
||||
|
||||
#### Download and deploy arthas tunnel server
|
||||
|
||||
[https://github.com/alibaba/arthas/releases](https://github.com/alibaba/arthas/releases)
|
||||
|
||||
Arthas tunnel server is a spring boot fat jar application, start with the `java -jar` command:
|
||||
|
||||
```bash
|
||||
java -jar arthas-tunnel-server.jar
|
||||
```
|
||||
|
||||
By default, the web port of the arthas tunnel server is `8080`, and the port connected by the arthas agent is `7777`.
|
||||
|
||||
Once started, you can go to [http://localhost:8080/](http://localhost:8080/) and connect to the registered arthas agent via `agentId`.
|
||||
|
||||
Through Spring Boot's Endpoint, you can view the specific connection information: [http://localhost:8080/actuator/arthas](http://localhost:8080/actuator/arthas), the login user name is `arthas`, and the password can be found in the log of arthas tunnel server, for example:
|
||||
|
||||
```
|
||||
32851 [main] INFO o.s.b.a.s.s.UserDetailsServiceAutoConfiguration
|
||||
|
||||
Using generated security password: f1dca050-3777-48f4-a577-6367e55a78a2
|
||||
```
|
||||
|
||||
#### Connecting to the tunnel server when starting arthas
|
||||
|
||||
|
||||
If you have suggestions for the Web Console, please leave a message here: [https://github.com/alibaba/arthas/issues/15](https://github.com/alibaba/arthas/issues/15)
|
||||
When starting arthas, you can use the `--tunnel-server` parameter, for example:
|
||||
|
||||
```bash
|
||||
as.sh --tunnel-server 'ws://47.75.156.201:7777/ws'
|
||||
```
|
||||
|
||||
* You can specify the agentId by the `--agent-id` parameter. By default, a random ID is generated.
|
||||
|
||||
After Arthas attach succeeds, the agentId will be printed, such as:
|
||||
|
||||
```bash
|
||||
,---. ,------. ,--------.,--. ,--. ,---. ,---.
|
||||
/ O \ | .--. ''--. .--'| '--' | / O \ ' .-'
|
||||
| .-. || '--'.' | | | .--. || .-. |`. `-.
|
||||
| | | || |\ \ | | | | | || | | |.-' |
|
||||
`--' `--'`--' '--' `--' `--' `--'`--' `--'`-----'

||||

|
||||
```
|
||||
|
||||
If the connection is not connected to the tunnel server at startup, you can also obtain the agentId through the `session` command after reconnection succeeds:
|
||||
|
||||
```bash
|
||||
[arthas@86183]$ session
|
||||
Name Value
|

JAVA_PID 86183
|
||||
SESSION_ID f7273eb5-e7b0-4a00-bc5b-3fe55d741882
|
||||
AGENT_ID URJZ5L48RPBR2ALI5K4V
|
||||
TUNNEL_SERVER ws://47.75.156.201:7777/ws
|
||||
```
|
||||
|
||||
|
||||
For the above example, go to [http://47.75.156.201:8080/](http://47.75.156.201:8080/) in the browser and input the `agentId` to connect to arthas on remote machine.
