Hi 

How can we configure a http monitor with username and password.

    You could type in the username & password on the 'new HTTP monitor' form (By new, I mean creating a new one, not that the form is new)

     

     

    Or make an external monitor via curl and include whatever you want in the headers...

        Don't forget to tell it what the expected response is for a successful query...

    What authentication method is supported on the web server you are trying to monitor?

     

    Basic Authentication and NTLM/NTLMv2 are supported methods under the HTTP and HTTPS Monitors.

     

    For NTLM to work the web server needs to respond with a 401 response status with a WWW-Authenticate header set to NTLM when it tries to authenticate with Basic Authentication, which it will do first.

        Then it's likely that you forgot to tell the monitor what constitutes a valid response. Otherwise it takes the fact that the login failed to be evidence that the site is up.
