Check VPS Resource Usage Every 15 Minutes

This n8n workflow template is designed to help system administrators and DevOps professionals monitor key resource usage metrics - CPU, RAM, and Disk - on a VPS (Virtual Private Server). The workflow automatically checks these resources every 15 minutes and sends an email alert if any resource usage exceeds the 80% threshold. This proactive monitoring helps maintain optimal server performance and prevents resource-related downtimes. # Who This Workflow Is For - **System Administrators** managing Linux-based servers who need to ensure their systems are running smoothly without manual monitoring. - **DevOps Professionals** who manage multiple environments and need automated tools to alert them to potential issues before they affect operations. - **IT Support Teams** who require an easy way to keep tabs on server health across an organization's infrastructure. # How It Works 1. **Schedule Trigger**: The workflow is triggered every 15 minutes by a Cron node. 2. **Resource Checks**: Separate SSH Command nodes are configured to execute specific commands that check the current usage of RAM, Disk, and CPU. 3. **Data Aggregation**: The results from each check are merged using a Merge node, which combines the data into a single payload for analysis. 4. **Threshold Analysis**: A Function node evaluates whether any resources' usage exceeds the predefined 80% threshold. 5. **Alerts**: If any metric exceeds the threshold, an email alert is sent through an Email node, ensuring that administrators can react promptly to potential issues. # Setup Steps 1. **Configure SSH Nodes**: Update each SSH node with the appropriate credentials and target server details where the resource checks will be performed. 2. **Set Thresholds**: If different sensitivity levels are required, review and adjust the resource usage thresholds within the Function node. 3. **Email Configuration**: Enter the correct email addresses in the Email node for where alerts should be sent. Ensure that your email-sending credentials and server details are correctly configured.
