Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
podman inspect metrics
Why it's wrong here
The 'podman inspect' command outputs detailed JSON configuration and state data for the container, but it is a static snapshot and does not stream live resource usage.
- ✗
podman top metrics
Why it's wrong here
The 'podman top' command displays the running processes inside a container, similar to the Linux top command, but does not show overall resource utilization statistics like CPU and memory percentages.
- ✗
podman system df metrics
Why it's wrong here
The 'podman system df' command reports storage space usage for containers, images, and volumes, not live CPU or memory performance.
- ✓
podman stats metrics
Why this is correct
The 'podman stats' command provides real-time CPU, memory, network, and block I/O usage statistics for containers.
