Container CPU and Memory Usage

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 access the Docker container and check the CPU and memory usage. In the command, {kbox_id} indicates the ID of the started instance.
```
# docker exec -it kbox_${kbox_id} sh
```
Run the following command to query the CPU and memory usage of the processes in the Docker container. See the following figure.
```
# top
```
If the memory usage of some processes keeps increasing and the CPU usage remains higher than 80%, check whether the processes are abnormal or contact Huawei technical support. For details about the parameters in the command output, see 3.
To view the real-time information about the CPU load, memory usage, and swap space, run the following command:
```
# ctop
```
The ctop command is run on the host. The parameters in the ctop command output are described as follows:
OWNER: process owner
TYPE: process type
PROC: process priority
MEMORY: memory
SYST: CPU usage of the system kernel space
USER: CPU usage of user processes
BLKIO: I/O resources
TIME+: total CPU time of the process in centiseconds
CGROUP: group name of the process owner
