Create your first uptime monitor

Set up continuous HTTP monitoring for a URL in under two minutes.

An uptime monitor checks a URL at a regular interval and opens an incident when it stops responding correctly. You'll need a WatchCat account — the free plan supports up to 5 active monitors with 3-minute checks.

Step 1 — open the new monitor form

From the monitors list, click Create Monitor. This opens the uptime monitor creation form.

Step 2 — enter the URL

Enter the full URL including the protocol — for example https://example.com or https://api.example.com/health.

For most cases, monitoring a dedicated health endpoint (e.g. /health or /up) is more reliable than the homepage, because it can verify database connectivity and other dependencies — not just that the web server responds.

Tip: Avoid monitoring URLs that require authentication or redirect to a login page. WatchCat follows redirects but won't log in — you'll get false positives if the final response returns a non-2xx status.

Step 3 — choose a check interval

The check interval controls how often WatchCat sends an HTTP request to your URL.

1 minute Customer-facing services, payment APIs (Pro & Team plans)
3 minutes General use, internal tools (all plans including Free)
5–30 minutes Low-criticality endpoints, batch APIs

Step 4 — set the confirmation period

The confirmation period controls how long checks must fail continuously before an incident is opened. A short period means faster alerts; a longer period filters out transient blips that resolve on their own.

For most services, 5 minutes is a good default. For critical APIs where every minute of downtime matters, use 1–2 minutes.

Step 5 — assign a notification channel

Under Notifications, select one or more notification channels to alert when the monitor goes down or recovers. If you haven't set up a channel yet, you can create one from Notification channels in the sidebar — the simplest option is a channel that emails all team members. How notification channels work →

Save the monitor. WatchCat will run the first check within the next interval and begin tracking uptime from that point.

What happens next

  • The monitor appears on your dashboard with its current status
  • Each check result is recorded — you can see response times and status codes in the monitor detail view
  • If checks start failing, WatchCat waits for the configured threshold before opening an incident and sending alerts
  • When the service recovers, the incident is closed automatically and a recovery alert is sent
