Creating HTTP monitors

URL monitoring with response validation.

Overview

HTTP monitors check website and API availability by making HTTP GET requests and validating responses. They verify that the server returns a successful response (status 200-299).

Creating an HTTP monitor

  1. Navigate to Uptime in the sidebar
  2. Click Create monitor
  3. Select HTTP/HTTPS as the monitor type
  4. Enter the target URL (include https:// or http://)
  5. Configure the settings below
  6. Click Create monitor

Configuration options

  • Name: A descriptive name for the monitor (max 50 characters)
  • URL: The full URL to monitor (must include protocol)
  • Check interval: How often to check (15 seconds to 30 minutes)
  • Ignore TLS errors: Skip SSL certificate validation if needed

Response validation

Turn on Advanced matching to validate the response body:

  • Match methodEqual, Include, or Regex.
  • Expected value — the string (or regex) to match.
  • JSON path — optional JMESPath expression. If set, Checkmate parses the body as JSON, evaluates the expression, and compares the result against Expected value. Leave blank to match the raw body.

See Response body matching for details.

HTTP monitors check for successful responses (status 200-299). The monitor uses GET requests by default.
