How do I check if a website is up?

[Josh Wells]

Ok I defined the command as you specified in my commands.cfg file. I
then added a service definition in my localhost.cfg file using that
command. It appears to be working. How do I configure an alert for this
type of check? I would like to be notified if the website is not
reachable for more than say 5 minutes. Also while this is functional I
don't really like that this website check is showing up under my nagios
server host. I would prefer that it have its own host definition or at
least appear separately from the other hosts. Is it possible to do this
using a URL?

Thanks for your help. I used the quickstart guide to get my server up
and running so still pretty green with nagios but I'm learning.

Josh

No , you don't have to define a host .

you define a service check with the fix parameters ( as i gave in the
previous mail ) and assign this check to an existing host .

that host will execute the check and report the status returned from the
command ( personally i'd run it from the nagios server itself) .
