NimbostratusUnable to monitor webserver with Siteminder,
Hi,
We tried to create http_monitor to monitor webservers with siteminder, we keep getting error 500 from the servers. I am not sure if there is something missing from your script.
Thanks
GET /unavailable_up.html HTTP/1.1\r\nHost: \r\nConnection: close\r\n
tried from ssh:
GET /unavailable_up.html

Which LTM version are you running? If you're on 9.3 - 10.1.0, can you try removing the trailing \r\n's:
GET /unavailable_up.html HTTP/1.1\r\nHost: \r\nConnection: close
And if that doesn't work, it's possible that the pool members require a valid host header value. If that's the case, can you hardcode the Host header value (replacing www.example.com with the actual Host the servers require):
GET /unavailable_up.html HTTP/1.1\r\nHost: www.example.com\r\nConnection: close

Chris_101737Still did not work

Thanks- hoolioHi Chris,
Did you set a valid Host header value in the monitor send string? Can you post the headers from a valid browser request to the site? You can use a browser plugin like HttpFox for Firefox or Fiddler for IE to capture the headers.
Thanks, Aaron
