This n8n workflow automates the process of creating snapshots of all VPS instances hosted on Hostinger, monitoring their metrics, and sending WhatsApp notifications about the success or failure of each snapshot. It simplifies VPS management by scheduling daily backups and alerting system administrators in real-time.
The workflow begins with a scheduled trigger set for 4:00 AM daily, automatically initiating the process. It retrieves a list of all VPS instances through the Hostinger API and filters only those that are currently ‘running’. For each active VPS, it fetches relevant metrics like CPU usage, RAM, disk usage, and uptime within the last 30 minutes.
Using this data, it creates a snapshot of the VPS. After attempting the snapshot, the workflow sends a WhatsApp message via Evolution API, reporting either a success with detailed metrics or an error message if the snapshot fails. Additionally, sticky notes provide visual notes and instructions within the workflow for easy setup and maintenance.
This setup is useful for hosting providers and system administrators who want to automate VPS backups, continuously monitor server health, and receive instant notifications, all while being capable of self-hosting the automation system.
