Using nagios check_http for web basedauthentication

[Venugopal S]

Hi Marc,

Thanks for the reply. I am even now vague about how to proceed.

Let me tell you the need :

I have to open http://ww12.1800flowers.com/signin.do and enter my
email(svenugopaal at gmail.com) and password("podhum") in order to login.

When I login using the above valid credentials it would take me to the
next page or otherwise throw an error.

How do I compose the command line for check_http ?

Though this looks like a lot of hand holding, I have no other go.

Can you please help ?

Venu

Since you're using forms based authentication, use the -P parameter to 
check_http.

$ ./check_http --help

[chop]

  -P, --post=STRING
     URL encoded http POST data


check_http -I <ipaddress of serve> -H www.venu.com -u /autorize.do -P 
"usernamefield=username&passwordfield=password"

If you need something more complex than that you might want to search 
for past posts about use of perl's WWW::Mechanize or 
Nagios::WebTransact to help create a custom plugin.

Note for future readers, if the site uses standard htaccess 
authentication then '-a username:password' if the format.
