The HTTP Sensor can monitor a specified website. It can be used to check the availability or the performance of the website.
The parsing options are only available if the 'Download' option is set to 'Everything' or 'Kilobytes'.
To get the value of a specific group as the result, the group must be named using the identifier 'value', e.g. '...(?<value>...)...'. If the regular expression contains only anonymous groups, the first one will be used as the result. If the expression has no group, the whole match will be used as the result.
The sensor uses the proxy settings of the service user. If you want to set proxy settings, be sure to set them for the correct user. If you use a service user, you can set the proxy settings with the tool "bitsadmin".
