a little change of it when you running on NRPE

If you get any error of NRPE server as “NRPE: Unable to read output” when you run this plugins, please add a line into the check_open_files.pl as below:

use lib “/usr/local/nagios/libexec”;

Because NRPE run this command by user nagios and it may need a path of file “utils.pm”.
