modbender Server Health Agent
Server Health Agent is a production-ready OpenClaw skill designed to provide real-time monitoring of key server health metrics. It helps developers, DevOps engineers, and system administrators quickly assess the operational health of their VPS or server.
This skill executes safe system-level read-only commands to collect accurate health metrics without modifying the system.
Key Features
Real-Time CPU Monitoring
Uses live system commands (top) to capture current CPU utilization, with fallback mechanisms to ensure reliability even in restricted environments.
Memory (RAM) Monitoring
Reports accurate RAM usage percentage using system-level commands and Node.js fallback logic.
Disk Usage Monitoring
Provides root filesystem disk utilization, allowing detection of storage pressure or capacity issues.
Docker Container Detection
Detects and reports running Docker containers and their status when Docker socket access is available.
Gracefully handles environments where Docker access is restricted.
Structured Output
Returns structured JSON output optimized for OpenClaw automation workflows and downstream processing.
Use Cases
This skill is useful for:
- VPS health monitoring
- DevOps automation workflows
- Infrastructure monitoring
- Troubleshooting performance issues
- Detecting resource bottlenecks
- Monitoring containerized environments
- Automated system health checks
