Schedule Trigger \nTriggers the workflow every minute to initiate regular checks on server availability.\n\nšŸ“„ 2. Web Servers List (Google Sheets) \nFetches a list of server hostnames or IP addresses from a Google Sheet. \nEach row is treated as one server. This makes server management easy — no need to edit the workflow to add/remove servers.\n\n🌐 3. Server Alive Check (HTTP) \nSends an HTTP GET request to each server (e.g., {{ $env.WEBHOOK_URL }} \nIf the request fails, the error path is triggered. \n\nšŸ“ 4. Web Server Alive Log (Google Sheets) \nLogs successful server checks into a separate Sheet with a timestamp.\nThis log helps track uptime history, verify server health, and generate availability reports.\n\nšŸšØšŸ“§ 5.
