HTTP Monitoring Sensor

The HTTP Request sensor is a full featured HTTP client, allowing you to monitor any aspect of your web site, application or server.

It supports HTTPS connections with certificate validation, cookies, a custom user agent, timeouts, wanted and unwanted string matches with regular expression support, and all HTTP response codes, allowing all aspects of your web server to be monitored for both performance and availability.

Parameters

URL
The URL to be monitored. Use the complete url, including http:// or https:// for a secure connection.

Expected HTTP Response
This will normally be 200 OK, however you can also monitor correct functioning of other HTTP responses such as 403 Forbidden, 302 Found.

Check SSL Certificate
Enable this option to verify that the web servers' SSL certificate is valid and issued by a recognized certificate authority.

Expected text
By including expected text, for the test to pass the supplied text must be found somewhere in the body of the HTTP response. Prefix this with regex: to do a perl-compatible regular expression match.

Unwanted text
Text that, if found in the HTTP response body, will cause the test to fail. Prefix this with regex: to do a perl-compatible regular expression match.

Cookies to send
Sends the contents of this parameter as an HTTP Cookie. Use the standard HTTP cookie format:

variable1=4142556; variable2=Your+Name+here

User agent string
Identifies the HTTP client as the supplied user agent. By default a blank agent string is sent.

Timeout
