Operating Environment Log Information

Use a remote terminal to log in to the server where the instruction stream cloud phone is deployed as the instruction stream cloud phone O&M user (for example, root).
Run the following command to switch to the root user:
```
su - root
```
If the instruction stream cloud phone container is abnormal, run the following command to obtain dmesg logs.
The dmesg logs contain device initialization logs, kernel module logs, and application crash information, which are helpful for subsequent cause analysis and fault locating.
