[Nagiosplug-help] run a plugin with a command that you have to be a root

[Nikolaos Loutzakis]

i have made a plugin that run correct in the terminal. but in order to execute this command you have to 
be root. to have root privileges. but when i insert the plugin in the nagios web interface it executes it 
wrong because it runs it as not a root . how can i make it run as root?
