๐ Server Agents Overview
Monitron Server Agents are lightweight scripts that run on your servers and report system metrics back to your Monitron instance. They give you full visibility into CPU, memory, disk, network, and load averages.

- An agent script runs on your server (via cron or Task Scheduler)
- It collects system metrics
- It sends them as JSON to your Monitron instance
- Monitron stores the metrics and updates the monitor status
- If the agent stops reporting for 5+ minutes, Monitron marks the server as Down
