Emby Cluster Monitor is a monitoring dashboard for Emby media servers, deployed as a serverless function on Cloudflare Workers. Emby is self-hosted media server software that lets you stream your personal movie and TV collection. This project lets you keep an eye on multiple Emby servers from a single web page without needing a dedicated server of your own. The dashboard regularly probes each configured server to check whether it is online and measures the response time. It stores the last seven days of probe results so you can view uptime percentages over the past 24 hours or seven days, and a history panel shows the most recent 60 check results for spotting short term fluctuations. When a server stays offline for five minutes, the tool sends an alert via Telegram, and when the server recovers, it sends a follow up notification. This delay filters out brief network glitches so you are not flooded with false alarms. Optional media library statistics track the number of movies, TV series, and episodes on each server, recording a daily snapshot and comparing it to the previous day so you can see what was added. A custom icon library feature lets you assign images to each server node by pointing to a publicly accessible JSON file with image URLs, and the icon library can be searched by name or by image link. All configuration, including the server list, icon library, and Telegram settings, is stored in Cloudflare KV, which is a key value storage service provided by Cloudflare, so settings persist across deployments without relying on a local browser. An admin token can be set to prevent unauthorized changes, and the worker refuses to probe internal or private network addresses so it cannot be used as a proxy to scan a local network. The entire project is a single JavaScript file deployed to Cloudflare Workers with a scheduled cron trigger running every five minutes.
