Power up your monitoring

By default, domains are checked every hour. The Frequent Monitoring add-on lets you mark up to 50 Priority Hosts for checks every 5 minutes.

How to enable

1. Open a domain and click Settings.
2. Toggle Frequent Monitoring on.
3. Return to the domain page and mark the hosts you want as Priority.
4. Those hosts start using the 5-minute cadence immediately.

Disabling the add-on reverts all hosts to the default hourly check schedule while preserving any Priority Host flags. Billing adjusts automatically at the next billing cycle.

By default, DNS change alerts are sent to the email address associated with your account. Team Notifications lets you route those notifications to additional destinations across your account for all monitored domains.

Supported channels

How to enable

1. Open Settings and click Notifications.
2. Toggle Team Notifications on.
3. Add one or more channels — email addresses, Slack webhooks, Discord webhooks, or generic webhook URLs.
4. Save. Future alerts for your domains will be delivered to all configured channels.

Connecting Slack

1. Click Add channel and select Slack.
2. Click Connect with Slack and sign in to your Slack workspace.
3. Choose the channel you want alerts posted to and click Allow.
4. You'll be redirected back and the channel will appear connected — no URL to copy or paste.

Connecting Discord

1. Click Add channel and select Discord.
2. Click Connect with Discord and authorize the connection.
3. Select the server and channel you want alerts posted to and click Authorize.
4. You'll be redirected back and the channel will appear connected — no URL to copy or paste.

Generic webhook payload

When a DNS change is detected, a POST request is sent to your URL with a JSON body:

{
  "app": "OneDollarDNS",
  "event": "dns_change_detected",
  "domain": "example.com",
  "host": "sub.example.com",
  "timestamp": "2024-01-01T00:00:00Z",
  "changes": [
    {
      "type": "MX",
      "change": "added",
      "old_value": null,
      "new_value": "mail.example.com"
    }
  ]
}

Test notifications use a different payload with "event": "test" so your handler can distinguish them:

{
  "app": "OneDollarDNS",
  "event": "test",
  "timestamp": "2024-01-01T00:00:00Z",
  "message": "This is a test notification. Your webhook channel is configured correctly."
}

Testing a channel

Each configured channel has a Send test button (the paper plane icon). Clicking it sends a one-off test notification to that channel immediately, so you can confirm the destination is reachable without waiting for a real DNS change. The delivery status badge updates after the attempt.

Test notifications are limited to 3 per channel per minute. Email channels receive a plain confirmation message; Slack and Discord channels receive a labeled test message; webhook channels receive the test payload shown above.

Delivery status

Team Notifications tracks the latest delivery attempt for each channel. Channels show a Delivered badge after a successful send, or a Failed badge when the latest attempt could not be delivered.

A failed webhook, Slack, or Discord channel does not stop other configured channels from receiving the same alert. Fix the destination URL or webhook configuration, and the status will clear after the next successful delivery.

Add-ons are independent and can be combined. You can enable Frequent Monitoring on individual domains and Team Notifications once for the whole account.
