Monitor your websites and APIs directly from Hub, without depending on external services.

​
Creating a Health Check

  1. Go to Health Checks in the dashboard
  2. Click Add
  3. Configure:
FieldDescription
NameDisplay name
URLFull URL to monitor
MethodGET, POST, HEAD
IntervalCheck frequency (seconds)
TimeoutMax wait time (seconds)
  1. Click Create

​
How Checks Work

Every interval, Hub:
  1. Sends HTTP request to the URL
  2. Records response time and status
  3. Marks UP if 2xx status code
  4. Marks DOWN if timeout or non-2xx
  5. Sends alert on status change

​
Expected Status Codes

By default, any 2xx (200-299) is considered healthy. To accept only specific codes:
  • 200 - Only 200 is OK
  • 200,201,204 - Accept these specific codes

​
Retry Logic

Before alerting, Hub retries failed checks:
SettingDefault
Retries3
Retry interval10s
Confirmation delay30s
This prevents false alerts from temporary network issues.

​
Alerts

Configure where to send alerts:
  1. Go to Settings → Notifications
  2. Set up Telegram or email
  3. New health check alerts go to configured channels

​
Viewing History

  • Uptime percentage (24h, 7d, 30d)

Internal vs External URLs

Hub can monitor:
  • External URLs: Public websites, APIs
  • Internal URLs: Services on your network (localhost, private IPs)
This is useful for monitoring internal services that aren’t publicly accessible.

​
Troubleshooting

  1. Check Hub has internet access
  2. Verify DNS resolution:
curl -I https://your-url.com
  1. Check firewall allows outbound HTTPS
Increase retry count or confirmation delay in check settings.
Hub measures from server location. High latency is normal for geographically distant services.
