Health Monitor — System Health & Performance Monitoring

Monitor agent health, performance metrics, and resource usage with automated alerting.

Overview

This skill provides:

• Health Checks: Ping services, check disk space, memory usage
• Metric Collection: Track CPU, memory, disk, network over time
• Anomaly Detection: Detect unusual patterns in metrics
• Automated Alerting: Send alerts when thresholds exceeded
• Uptime Tracking: Monitor service availability
• Performance Reports: Generate health reports

Metrics Tracked

• System: CPU%, memory usage, disk space, load average
• Process: Node.js heap, event loop lag, active handles
• Application: Job queue depth, error rate, response time
• External: API latency, dependency health

Configuration

{
  "checks": [
    {
      "name": "disk-space",
      "type": "metric",
      "threshold": 90,
      "unit": "%",
      "interval": "*/5 * * * *"
    },
    {
      "name": "api-latency",
      "type": "http",
      "url": "https://api.anthropic.com",
      "threshold_ms": 5000
    }
  ],
  "alerts": {
    "channels": ["telegram"],
    "quiet_hours": { "start": "22:00", "end": "08:00" }
  }
}

API

const { checkHealth, getMetrics, getUptime } = require('./health-monitor');

// Run health checks
const health = await checkHealth();

// Get current metrics
const metrics = getMetrics('last_hour');

// Get uptime percentage
const uptime = getUptime('daily'); // "99.5%"
