System Monitor

Comprehensive system health monitoring for AI agents. Monitors disk usage, memory, processes, network connectivity, and service health.

When to Use

Use this skill when you need to:

• Check overall system health
• Monitor disk space and prevent outages
• Track memory usage and detect leaks
• Verify critical services are running
• Monitor network connectivity
• Get system performance metrics
• Set up automated health alerts

Triggers

• "check system health"
• "monitor disk space"
• "check memory usage"
• "system status"
• "health check"
• "performance monitor"
• "service status"
• "system metrics"

Quick Start

# Basic health check
node scripts/monitor.js

# With custom thresholds
node scripts/monitor.js --disk-threshold 90 --memory-threshold 85

# JSON output for automation
node scripts/monitor.js --json

# Monitor specific services
node scripts/monitor.js --services "openclaw,postgresql,redis"

# Continuous monitoring (5 min intervals)
node scripts/monitor.js --watch --interval 300

Configuration

Create .system-monitor.json in your skill directory:

{
  "thresholds": {
    "disk": 85,
    "memory": 80,
    "cpu": 90
  },
  "services": ["openclaw", "postgresql", "redis", "nginx"],
  "networks": ["8.8.8.8", "1.1.1.1"],
  "ports": [22, 80, 443, 18800],
  "alerts": {
    "webhook": "https://hooks.slack.com/...",
    "email": "admin@example.com"
  }
}

Outputs

The skill provides:

• Disk usage by mount point
• Memory usage (total, used, free, cached)
• CPU load averages
• Running process count
• Network connectivity status
• Service health checks
• System uptime
• Temperature monitoring (if available)
• Alert notifications when thresholds exceeded

Examples

# Morning health check
node scripts/monitor.js --summary

# Pre-deployment check
node scripts/monitor.js --strict

# Export metrics for logging
node scripts/monitor.js --json > system-metrics-$(date +%Y%m%d).json

# Watch for issues
node scripts/monitor.js --watch --alert-webhook "https://hooks.slack.com/..."

Perfect for cron jobs, deployment pipelines, and proactive monitoring.
