Automated Server Resource Monitoring and Alerting
detail.loadingPreview
Proactively monitor your server's CPU, RAM, and Disk usage with automated alerts. This workflow ensures you're notified when resources exceed critical thresholds, preventing downtime and performance issues.
About This Workflow
This n8n workflow provides a robust solution for real-time server resource monitoring. It intelligently checks CPU, RAM, and Disk utilization at regular intervals (every 15 minutes). If any of these key metrics surpass a configurable threshold (defaulting to 80%), an immediate email notification is dispatched. This proactive approach empowers you to address potential bottlenecks before they impact your services, ensuring optimal performance and reliability for your infrastructure. The workflow is designed for ease of setup and customization, allowing you to tailor alerting and thresholds to your specific needs.
Key Features
- Scheduled Monitoring: Automatically checks resource usage at user-defined intervals (e.g., every 15 minutes).
- Comprehensive Resource Tracking: Monitors CPU, RAM, and Disk utilization.
- Customizable Thresholds: Easily adjust the alert trigger percentage for each resource.
- Instant Email Alerts: Receives immediate email notifications when resource usage is high.
- SSH Integration: Leverages SSH to gather resource data directly from your server.
How To Use
- Schedule Trigger: Configure the
Schedule Triggernode to set the desired monitoring interval (default is 15 minutes). - SSH Nodes: Set up the
Check RAM usage,Check Disk usage, andCheck CPU usagenodes. Ensure your SSH credentials are correctly configured and thecommandparameters accurately reflect how to retrieve resource usage for your operating system. - Merge Check Results: The
Merge check resultsnode combines the output from the SSH nodes. Ensure thequeryparameter correctly maps the resource outputs. - Check Results Against Thresholds: Configure the
Check results against thresholdsnode to set your desired alert levels (default is 80%). ThecombineOperationset toanywill trigger an alert if any single resource exceeds its threshold. - Send Email: Update the
Send Emailnode with your desiredtoEmailandfromEmailaddresses and configure your SMTP credentials. The email content will dynamically include the current resource usage percentages.
