VPS Resource Usage Monitoring and Alerting

This workflow focuses on resource monitoring and alerting for VPS servers, capable of automatically checking CPU, memory, and disk usage every 15 minutes. Once any resource usage exceeds the preset threshold of 80%, the system immediately notifies the operations personnel via email, ensuring a timely response to prevent performance degradation or service interruption. This automated monitoring not only saves manual inspection time but also significantly enhances system stability and operational efficiency, making it suitable for various IT infrastructure management scenarios.

Workflow Name

VPS Resource Usage Monitoring and Alerting

Key Features and Highlights

This workflow enables scheduled monitoring of VPS server CPU, memory (RAM), and disk usage. It supports automatic resource usage data collection every 15 minutes and real-time evaluation against preset thresholds (default set at 80%). Once any resource usage exceeds the threshold, an automatic email notification is triggered to alert about potential system resource constraints. This helps operations personnel respond promptly, preventing service interruptions or performance bottlenecks.

Core Problems Addressed

Prevents performance degradation or downtime risks caused by server resource overload by implementing automated monitoring and alerting. This reduces manual inspection costs while enhancing system stability and operational efficiency.

Application Scenarios

  • Monitoring VPS or cloud server resource usage
  • Automated alerting systems for IT operations
  • Enterprise IT infrastructure management
  • Performance warning in DevOps environments
  • Any scenario requiring periodic server resource checks with automatic alerts

Main Process Steps

  1. Scheduled Trigger: Initiates the monitoring workflow every 15 minutes.
  2. Check RAM Usage: Executes SSH commands to retrieve current RAM usage percentage.
  3. Check Disk Usage: Uses SSH commands to obtain disk usage percentage of the root directory.
  4. Check CPU Usage: Retrieves current CPU utilization via SSH commands.
  5. Merge Check Results: Consolidates CPU, memory, and disk usage data into a single record.
  6. Evaluate Against Thresholds: Determines if any metric meets or exceeds the 80% threshold.
  7. Send Alert Email: Automatically sends an email notification to designated recipients if any resource exceeds the threshold.

Involved Systems or Services

  • SSH Remote Execution: Used to remotely run Linux commands to fetch CPU, RAM, and disk usage data.
  • SMTP Email Service: Configured SMTP account to send alert emails.

Target Users and Value

  • Server Operations Engineers: Automate resource monitoring and alerting to minimize manual intervention.
  • IT Administrators: Gain timely insights into server status to ensure business continuity.
  • DevOps Teams: Integrate into automated workflows to enhance system reliability.
  • Small and Medium Enterprises and Individual Site Owners: Cost-effective solution for basic infrastructure health monitoring and alerting.

This workflow is streamlined and efficient, easy to deploy and extend. It supports user customization of thresholds and recipient email addresses, making it a practical tool to ensure stable server operation.
