System Log Information

Use an SSH tool such as Xshell to log in to the server where the video stream cloud phone is deployed as the cloud phone O&M user (for example, root).
Switch to the root user.
```
su - root
```
Go to the /var/log directory on the server to view syslog and other kernel logs.

The syslog file records alarm information, which is usually the information about system faults.

Other kernel files include core startup logs (dmesg), system error logs (messages), login records (wtmp), and boot logs (boot.log).
