Automated Monitoring for OpenClaw Bots: A Practical Guide

Manual monitoring means you find out your bot is down when a user complains. Automated monitoring means the crash is fixed before most users notice. Here's how to set it up โ€” from simple cron scripts to a full repair agent.

The monitoring gap in OpenClaw

OpenClaw doesn't include built-in uptime monitoring. When the gateway process dies, nothing alerts you. You find out via:

The average developer finds out 4โ€“6 hours after the crash. By then, multiple users have already bounced.

Option 1: Simple cron watchdog (free, DIY)

The cheapest approach: a cron job that checks the process and restarts it if dead.

watchdog.sh
#!/bin/bash
# Simple OpenClaw watchdog โ€” add to cron: */5 * * * * /path/to/watchdog.sh

LOG="/var/log/openclaw-watchdog.log"
TS=$(date '+%Y-%m-%d %H:%M:%S')

if ! pgrep -f "openclaw-gateway" > /dev/null; then
  echo "[$TS] Gateway not running โ€” restarting" >> "$LOG"
  systemctl restart openclaw-gateway 2>> "$LOG" || \
    openclaw gateway restart 2>> "$LOG"
  
  # Optional: send Telegram alert
  # curl -s "https://api.telegram.org/bot${BOT_TOKEN}/sendMessage" \
  #   -d chat_id="${CHAT_ID}" \
  #   -d text="โš ๏ธ Gateway restarted at $TS" > /dev/null
else
  echo "[$TS] Gateway OK" >> "$LOG"
fi
Add to crontab
# Run every 5 minutes
*/5 * * * * /usr/local/bin/openclaw-watchdog.sh 2>&1
Limitation

This works for simple restarts. It won't handle config corruption, disk full errors, or know why the gateway died โ€” it just restarts blindly. Which is fine until it isn't.

Option 2: systemd with auto-restart (slightly better)

If you're on Linux, systemd can restart the gateway on crash with a configurable delay:

/etc/systemd/system/openclaw-gateway.service
[Unit]
Description=OpenClaw Gateway
After=network.target

[Service]
User=your-username
WorkingDirectory=/home/your-username/.openclaw/workspace
ExecStart=openclaw gateway start --foreground
Restart=on-failure
RestartSec=10s
# Stop auto-restart after 5 tries in 5 minutes (prevents crash loops)
StartLimitInterval=300
StartLimitBurst=5

[Install]
WantedBy=multi-user.target

This catches simple crashes. But it still won't tell you what happened, and it won't fix config corruption or disk issues.

Option 3: Full automated repair agent

This is what Mechanic Bot does. Instead of a dumb restart, it:

DIY watchdog

  • Detects crash ~5 minutes late
  • Restarts blindly (fails if config broken)
  • No notification to you
  • No logging of what was wrong
  • Loops if root cause isn't fixed

Mechanic Bot

  • Detects within 60 seconds
  • Diagnoses before restarting
  • Repairs config corruption safely
  • Notifies you via Telegram + email
  • Full repair audit trail

What "automated repair" actually means

When Mechanic detects the gateway is down, it runs through a decision tree:

Gateway crash repair sequence

1. Check process is actually dead (not just slow) 2. Check disk space (>90% = clear logs first) 3. Validate config file (parse JSON, check required keys) โ†’ If broken: backup โ†’ deep-merge repair โ†’ preserve all tokens โ†’ If OK: proceed to restart 4. Attempt restart via systemd / launchctl / openclaw gateway 5. Verify restart succeeded (ping gateway health endpoint) 6. Send Telegram/email notification with outcome 7. Write audit trail entry 8. If failed after 3 attempts: escalate to manual repair

The key difference: step 3. Dumb restart fails silently if the config is broken. A repair agent fixes the underlying cause.

Setting up Mechanic Bot

One command installs the monitoring agent on your Linux VPS or Mac:

Linux VPS
curl -fsSL https://mechanicbot.io/onboard.sh | sudo bash -s -- \
  --token YOUR_TOKEN \
  --email you@example.com
Mac
curl -fsSL https://mechanicbot.io/onboard-mac.sh | bash -s -- \
  --token YOUR_TOKEN \
  --email you@example.com

The agent runs as a non-root systemd service (Linux) or launchd service (Mac), connects to the Mechanic hub via WebSocket, and starts monitoring your gateway within 30 seconds.

What you get

14-day free trial, no credit card. Works on Ubuntu, Debian, Raspberry Pi, macOS. Installs in about 4 minutes.

Stop debugging 3am crashes manually.

Mechanic Bot monitors your OpenClaw bot 24/7 and fixes crashes automatically. You get notified when it fixes something โ€” not when it fails to.
