Bud Health Monitor

Prompts

Monitor system health (RAM, disk, CPU, services). Auto-detect issues and attempt fixes. Essential for keeping Raspberry Pi running stable.

Install

openclaw skills install bud-health-monitor

Health Monitor 🩺

System health monitoring with auto-fix capabilities. Monitors RAM, disk, CPU, and services. Detects problems before they crash your Pi.

Designed for Raspberry Pi and home server setups where resources are limited.


Quick Start

# Check system health
python3 ~/.openclaw/health-monitor/health_monitor.py status

# Watch continuously (refreshes every 30s)
python3 ~/.openclaw/health-monitor/health_monitor.py watch

# Auto-fix low RAM issues
python3 ~/.openclaw/health-monitor/health_monitor.py fix

What It Monitors

ResourceWarningCritical
RAM80%90%
Disk85%95%
CPU85%95%

Commands

status — Show health report

Shows current usage for RAM, disk, CPU, load average, uptime, and top processes by RAM usage.

watch — Continuous monitoring

Refreshes every 30 seconds. Use Ctrl+C to stop.

fix — Auto-fix low RAM

Terminates processes using >5% RAM (except critical system services). Also drops caches to free memory.

json — Machine-readable output

Outputs full status as JSON for integration with other tools.


Auto-Fix Capabilities

When RAM gets critical, the skill can:

  1. Terminate processes using too much RAM (SIGTERM → SIGKILL)
  2. Drop system caches (sync && echo 3 > /proc/sys/vm/drop_caches)
  3. Log events to ~/.openclaw/health-monitor/health.log

Requires sudo-tool to be installed for full functionality.


Alert Thresholds

Alerts are shown when thresholds are exceeded:

  • 🟡 WARNING — resource above warning threshold
  • 🔴 CRITICAL — resource above critical threshold

Integration

Add to cron for automated health checks:

# Check every 5 minutes, log if issues found
*/5 * * * * python3 ~/.openclaw/health-monitor/health_monitor.py status | grep -q "ALERTS" && echo "Health issue detected" | mail -s "Pi Alert"

Or trigger a fix automatically when RAM gets critical:

# At RAM critical, run fix
0 * * * * python3 ~/.openclaw/health-monitor/health_monitor.py json | python3 -c "import sys,json; exit(1 if json.load(sys.stdin)['ram']['percent'] > 90 else 0)" && python3 ~/.openclaw/health-monitor/health_monitor.py fix

Required By

  • vpn-mesh — keeps node running stable
  • OANDA bot — prevents crashes from RAM exhaustion
  • Any heavy workload — automated health management

Known Issues

  • Disk at 91% on this system — needs cleanup
  • Some processes cannot be killed without root (but sudo-tool handles this)
