Troubleshooting

  1. Verify bot token is correct
  2. Ensure you’ve sent a message to the bot first
  3. Check chat_id matches your chat
  4. Try “Send Test” button
  1. Increase thresholds (e.g., CPU 80% → 90%)
  2. Add alert delay (5 minutes)
  3. Use mute during known high-usage periods
Alerts auto-resolve when condition clears. If stuck:
  1. Check current metric values
  2. Manually clear in Alert History
