[Nagiosplug-help] check_http problem

[Alex Griffin]

Can you post your command definition? In the mean time, when you test 
plugins from the command line, make sure you run them as the nagios 
user. In this case I doubt it would make a difference unless your 
machine is really locked down, but sometimes it makes a very big difference.
