Not at all. It just means that root can run a program successfully when
called directly. The question you should be asking is does the command{}
definition for this plugin use that full path? The default configs
typically use the $USER1$ macro for the path which must be properly set
in resource.cfg. Is $USER1$ pointing to the correct path? Is
resource.cfg being loaded by nagios?

Also, as pointed out previously, the plugins are never run as the root
user, always the nagios user. While it's not likely in this case, the
nagios user certainly isn't guaranteed the same access privileges as the
root user. You should always perform plugin tests as the nagios user.
