command Previously, if a container was not running, and the user ran the `podman stats` command, an error would be reported: `Error: container state improper`. Podman now reports stats as the fields' default values for their respective type if the container is not running: ``` $ podman stats --no-stream demo ID NAME CPU % MEM USAGE / LIMIT MEM % NET IO BLOCK IO PIDS CPU TIME AVG CPU % 4b4bf8ce84ed demo 0.00% 0B / 0B 0.00% 0B / 0B 0B / 0B 0 0s 0.00% ``` Closes: #14498 Signed-off-by: Jake Correnti <jcorrenti13@gmail.com>
