How do I check if a website is up?

[Ben O'Hara]

What i have done in the past is,

a) create a host for www.example.com
b) ceate a host group - "External"
c) stick www.example.com in Eternal group
) add service check to host

Yu can then add numberous external checks into the group or check other
services on the host.

Seemed to make sense that way for me back then
