Running a self-hosted stack feels great. You spin up your first container, set up your first Nginx reverse proxy, maybe a Plex or Jellyfin server. It all feels great running your server, owning your hardware, software stack, data, and defining your own rules. Except when it comes crashing down. Trust me, as a seasoned self-hoster, even I’m guilty of losing track of what’s happening under the hood. As your stack grows, containers crash, memory spikes happen, hard disks or SSDs start filling up, and you find yourself SSH-ing into your machine trying to make sense of everything.
