OK, more tests.

check_http with verbose output

OMD[gearman]:~$ ./lib/nagios/plugins/check_http -vv -H www.sprint.net
GET / HTTP/1.1
User-Agent: check_http/v1.4.15 (nagios-plugins 1.4.15)
Connection: close
Host: www.sprint.net


CRITICAL - Socket timeout after 10 seconds

so lets test with low level telnet 


OMD[gearman]:~$ telnet www.sprint.net 80
Trying 2600::...
Connected to www.sprint.net.
Escape character is '^]'.
GET / HTTP/1.1
Host: www.sprint.net

HTTP/1.1 302 Moved Temporarily
Server: HTTP Proxy/1.0
Connection: Close
Content-Length: 0
Location: https://www.sprint.net/


Server: HTTP Proxy/1.0 ??

Lets do a http 1.0 request


OMD[gearman]:~$ telnet www.sprint.net 80
Trying 2600::...
Connected to www.sprint.net.
Escape character is '^]'.
GET / HTTP/1.0

HTTP/1.1 200 OK
Set-Cookie: ServerID=1125; path=/
Date: Fri, 24 Feb 2012 07:26:04 GMT
Content-Type: text/html
Connection: close
Server: Apache/2.2.21 (Unix)

Now its an Apache 2.2.22 ??

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing 
also focuses on allowing computing to be delivered as a service.
