Oops cc'd the wrong list - although nagios-users would help you better 
here as it's not a plugin issue.

Hi Mike,

Firstly don't forget to CC in the list so others can benefit from answers.
Secondly, the config file you've given doesn't contain the definition 
for the service "Current Http" which is what Nagios is complaining about.

Therefore it's either defined in a different config file, or you haven't 
given us the complete localhost.cfg (which would be better if you 
attached it or only paste the relevant section of it.)

Nagios isn't complaining that the "check_http" command isn't defined 
(which as you've identified, it is) - it's complaining that a command 
called "check_http -H 192.168.0.5" isn't defined, which means you've got 
an incorrect syntax in the service definition for "Current Http" on 
"localhost."

I think you need to read up more about how to define services, and using 
macros such as $HOSTADDRESS$ to your advantage.
