Alerting - Notifications Across Every Channel

Stay Informed When It Matters Most

The best monitoring is useless if you hear about problems too late. live24h notifies you through the channel of your choice – in real time, reliably and without false alarms.

Notification Channels

Email

Available on all plans. Detailed outage reports with error details, response times and a direct link to your dashboard.

Webhook

Available from the Pro plan. Send alerts to any endpoint – ideal for integration with your own systems or custom workflows.

{
  "event": "check.down",
  "check": "api.example.com",
  "status": 503,
  "responseTime": 12450,
  "downSince": "2025-01-15T10:23:00Z"
}

Telegram

Available from the Pro plan. Receive notifications directly on your smartphone – fast, simple and available anywhere.

Slack, Discord, Microsoft Teams

Available from the Pro plan. Direct alerts in your team chat – right where your team communicates anyway.

PagerDuty, Opsgenie

Available from the Business plan. On-call management and escalation policies for critical infrastructure.

SMS

Available from the Business plan. SMS credits are included per tier (Business 25 / Agency 75 / Enterprise 250). The extra_sms_100 add-on (100 SMS for EUR 9.90) can be purchased separately.

One-Click Channel Test

Don’t leave it to chance: the “Send test” button lets you verify every configured channel directly from the dashboard – no need to wait for a real outage. You see immediately whether the notification arrives or where the problem lies.

In practice, delivery often fails silently: an expired webhook, a Teams app update, a spam filter. With the channel test, you know in seconds whether everything is working.

Intelligent Notifications

• Confirmation mechanism: Only notify when a downtime is confirmed
• Recovery notification: Automatic all-clear on recovery
• Aggregation: No notification flood when multiple checks are affected
• Quiet hours: Optional muting outside of business hours – configurable per channel
• Maintenance windows: Schedule planned maintenance so alerts are suppressed and the status page shows a banner

Reminder Ladder: Recurring Reminders (Business and Up)

Open incidents must not be forgotten. The reminder ladder keeps sending recurring reminders while a check is down – and every channel is tuned individually:

• SMS pings every 15 minutes until someone reacts
• Email follows up every 4 hours – no inbox flood
• Slack channel gets a ping every 30 minutes

live24h’s per-channel override for reminders is a rare capability in the EU monitoring market – most tools only offer account-wide recurring notifications, where every channel runs at the same cadence or none.

Escalation Policies with Acknowledge Buttons (Agency and Up)

If level 1 does not respond, level 2 should take over – not be alerted on top, but only after a grace period expires. The live24h Agency plan delivers:

• Up to 3 escalation policies with 5 levels each
• Every level has its own recipient and wait time (e.g. “15 min without ACK -> level 2”)
• Acknowledge buttons in emails: HMAC-signed links, valid for 72 h, no login required. Click = incident marked as “being handled”, levels 2-5 are stopped

Professional on-call rotations without a premium upcharge: EUR 79/month for Agency – the combination of escalation policies, HMAC-signed acknowledge buttons and EU hosting is still uncommon in the European market at that price point.
