HotHost
HotHost answers the only two questions that matter about every server you own, is it up and is the disk about to fill, before your users ask them instead. One web container collects metrics from a tiny agent you paste onto each host as a Docker or shell snippet, and the fleet lands in a single table: hostname, public IP, RAM and disk usage, CPU model and cores, swap state, and country. Disk and RAM get loud ALERT badges at a configurable threshold, ninety percent by default, and notifications fire on failure and again on recovery, so a resolved incident closes its own loop. The same console watches your websites directly, requesting each URL on your interval and checking the status code, a required keyword in the response, or basic auth behavior. SSL certificates get an expiration reminder fourteen days out by default, long before the browser warnings start. When memory climbs, the top ten RAM-consuming processes are charted over the last two days, turning "something is eating the box" into a named culprit. Alerts route through Email, Slack, Telegram, or Gmail plugins, and the plugin system accepts your own notifiers. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
