I made a script to extend the banner functionality. Curious if anyone would find it useful. If so, I will look at starting a feature/pull request.
The script is run as a custom entry in dietpi-banner. It reports:
1.network traffic inside dynamically discovered network namespaces (ip netns), useful if you run containers (I have podman pods, so containers are aggregated into combined netns’s)
2.used space in dynamically discovered filesystems (user can specify glob or regex matching)
3.basic system health checks (to be expanded?)
a.number of systemd services failed
b.number of IPs banned by fail2ban
