Docker is an invaluable tool in a self-hosted setup, and I spend a lot of time managing containers and monitoring their activity. I previously built a Docker Swarm cluster and could monitor the container activity to some extent. However, the one thing that I miss is hardware resource consumption, and there’s no option for it in Portainer. I tried my luck with Uptime Kuma, which is a good way to monitor and get notifications about each container’s status. Sadly, it doesn’t include hardware resources monitoring.
