Automate Hostinger VPS CPU Monitoring with Anthropic AI

Automate Hostinger VPS CPU Monitoring with Anthropic AI

Unlock seamless automation and fortify your server management with our advanced workflow designed specifically for Hostinger VPS users. This powerful n8n workflow consistently monitors CPU usage and network traffic, ensuring your server's stability and efficiency. In cases of significant CPU spikes, it leverages Anthropic AI to deliver precise diagnostics and strategic recommendations, enabling you to take prompt, informed actions.

What this workflow does

• Every 15 minutes, it loads your VPS ID, SSH host details, alert email, and custom CPU/traffic thresholds.
• Gathers CPU and network traffic data from the Hostinger API for the last two hours, identifies excess CPU usage, and detects traffic anomalies.
• In case of a CPU spike, it connects over SSH to run ps aux --sort=-%cpu, pinpointing and prioritizing high-CPU processes.
• Sends the processes to Anthropic (Claude), generating a concise diagnostic and recommendation report.
• If the spike is traffic-induced, it automatically initiates a Hostinger “lockdown” firewall, limiting access to pre-defined ports, and alerts you via email.
• For non-traffic-driven spikes, it logs a case entry for manual approval, notifying you through a detailed email including AI analysis and an approval path.
• Monitors emails for approval commands to terminate high CPU processes, and if approved, creates a VPS snapshot.

Use cases

• Automatically manage and control unexpected CPU usage on your VPS without constant manual monitoring.
• Enhance server security by quickly establishing a firewall during traffic anomalies.
• Receive actionable insights with AI-informed diagnostics for precise and timely decision-making.
• Utilize automated logging and approval processes to maintain a clear audit trail of all actions.
