Troubleshooting

Exporter shows 0 skills:

• Set OPENCLAW_SKILLS_DIR environment variable
• Default: /opt/homebrew/lib/node_modules/openclaw/skills

Prometheus can't scrape:

• Check both services are running
• Verify ports 9090 and 9101 are not blocked
• Check logs: /tmp/prometheus.log and /tmp/openclaw-exporter.log

Permission denied:

• Ensure the binary is executable: chmod +x openclaw_exporter
• Check file paths in plist/service files
