Proactive Server Monitoring & Alerting
detail.loadingPreview
Automate your server's health checks with this n8n workflow. Get instant email alerts when CPU, RAM, or Disk usage exceeds critical thresholds, ensuring you're always one step ahead of potential issues.
About This Workflow
This n8n workflow provides an automated solution for proactive server resource monitoring. It connects to your servers via SSH to regularly check CPU, RAM, and Disk utilization. If any of these vital metrics climb above a customizable 80% threshold, an immediate email notification is dispatched. This ensures you are alerted to potential performance bottlenecks or capacity issues before they impact your services. The workflow is designed for easy integration and customization, allowing you to adjust thresholds and email recipients to fit your specific operational needs.
Key Features
- Automated Resource Monitoring: Continuously checks CPU, RAM, and Disk usage.
- Customizable Thresholds: Easily adjust the 80% alert trigger for each resource.
- Real-time Email Alerts: Receive immediate notifications when resources are strained.
- SSH Integration: Securely connects to your servers for data retrieval.
- Flexible Configuration: Simple setup for email recipients and notification content.
How To Use
- Schedule Trigger: Configure the
Schedule Triggernode to run the workflow every 15 minutes (or your desired interval). - SSH Nodes: Update the
Check RAM usage,Check Disk usage, andCheck CPU usagenodes with your server's IP address and SSH credentials. Ensure theVMCCUQkaq46q3CpBcredential is set up correctly. - Threshold Adjustment: Modify the
Check results against thresholdsnode. Update thevalue2parameter for each resource to set your desired alert threshold (e.g.,80for 80%). - Email Configuration: In the
Send Emailnode, replacechange@me.comwith your actual sender and recipient email addresses. Ensure your SMTP credentials (EuaQtRc5t8pWPY9b) are correctly configured. - Merge Results: The
Merge check resultsnode combines the data from the SSH checks. Thequeryparameter is set up to select the CPU, Disk, and RAM usage. No direct modification is usually needed here unless you have complex merging requirements. - Activation: Once configured, activate the workflow to start receiving automated monitoring and alerts.
