Guard Hostinger VPS CPU spikes with Anthropic, SSH, and email approvals
UnknownUnknown. This template uses community nodes we can't verify statically. Uses community nodes that can't be verified statically (unverified community packages are off by default in 3.0). Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 39 nodes and runs on a schedule (every 15 minutes) (plus 1 other trigger). Along the way it connects Anthropic and Hostinger Api (community).
How it runs
Trigger: On a schedule (every 15 minutes) (plus 1 other trigger).
- Config: Detection Settings (Edit Fields (Set)): sets 8 fields: vpsId, notificationEmail, cpuThreshold…
- Extract Case ID & Decision (Code): runs custom JavaScript code
- Get VPS Metrics (Hostinger Api): get vm metrics
- Case ID Found & Approved? (If): checks a condition and branches into true / false
- Analyze Metrics (Code): runs custom JavaScript code
- Config (Kill Listener) (Edit Fields (Set)): sets 3 fields: vpsId, sshHost, notificationEmail
- CPU Spike? (If): checks a condition and branches into true / false
- SSH: uses SSH
- Get CPU Process List (SSH): uses SSH
- Parse Case (Code): runs custom JavaScript code
…plus 25 more steps. See the full node list below.
Services it uses
Before you upgrade to n8n 3.0
We can't fully verify this one: it relies on 1 community package, and n8n 3.0 turns unverified community packages off by default (N8N_UNVERIFIED_PACKAGES_ENABLED=false).
- Check that n8n-nodes-hostinger-api is verified or supports 3.0 (used in Create Snapshot, Get VPS Metrics, List Firewalls).

Quick overview This workflow monitors a Hostinger VPS every 15 minutes for CPU spikes, correlates them with traffic anomalies, and either auto-activates a lockdown firewall or emails a process report with AI analysis and an email-reply approval path to…
