logcat 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
```
Run the following command to query the container ID:
```
docker ps -a
```
Run the following command to query real-time server logs. In the command, {kbox_id} indicates the container ID.
```
docker exec -it kbox_${kbox_id} logcat
```
If you only need to view instruction stream engine logs, run the following command:
```
docker exec -it kbox_${kbox_id} logcat | grep "VMI"
```
