Uptime Monitors

Uptime monitors check your websites and APIs at regular intervals and alert you when they go down. Upmetr includes HTTP retries, recovery thresholds, SSL certificate tracking, and maintenance mode.

​

Creating a Monitor

1. Navigate to Monitors
2. Click Add Monitor
3. Configure the settings:

4. Click Save

The monitor starts checking immediately.

​

How Checks Work

Each check follows this flow:

1. HTTP request sent to the URL
2. If the request fails, Upmetr retries up to 2 more times (3 total attempts) with a 1-second delay between retries
3. If all attempts fail, the check is marked as down
4. After reaching the failure threshold, an incident is created

​

Anti-Flapping (Recovery Threshold)

To prevent alert noise from intermittent issues, monitors use a recovery threshold:

• When a monitor goes down, it stays in the “down” state
• When it starts responding again, Upmetr requires N consecutive successful checks before marking it as “up” and auto-resolving the incident
• Default recovery threshold is 2 — the monitor must pass 2 checks in a row before recovering

​

SSL Certificate Monitoring

For HTTPS URLs, Upmetr automatically tracks SSL certificates:

• Certificate validity — Is the certificate valid?
• Expiration date — When does it expire?
• Days until expiry — Countdown displayed in the UI

​

SSL Alerts

SSL alerts are automatic — no additional configuration needed.

​

Monitor Status

​

Maintenance Mode

Put a monitor in maintenance mode to temporarily pause checks without deleting the monitor:

1. Open the monitor detail page
2. Toggle Maintenance Mode on
3. Checks are paused — no alerts will fire

When maintenance is disabled, checks resume at the next interval.

​

Metrics & History

Each monitor tracks:

• Response time — Latency in milliseconds
• Uptime percentage — Rolling 24h, 7d, 30d
• Daily uptime aggregates — Historical availability data
• Incident history — Timeline of down events

View these on the monitor detail page (click any monitor in the list).
