问题

I need to see how much resources every running container on a RHEL 8 system is using.How can I monitor CPU, memory, disk, and network resources containers are using in real time?

决议

Use podman stats to view real-time resource consumption for containers running on RHEL 8. Using the --all option provides output for all running containersUsing --no-stream will do a 1-second poll, report the container's resource details and then exit, otherwise podman stats will continue to poll until interrupted.
