    Please re-format the code. Remove unnecessary blank lines. Use Ctrl + K or the `{}` button in the button bar to format line(s) as code blocks. – Harry Nov 24 '13 at 06:39

From experience my guess is this is a permission issue: The nagios user (which the plugin/script is running as) does not have privileges to read the file. You can fix file and directory permissions (maybe log to a different path if possible?) or run the script using sudo.

Worth attempting: it looks like you mispelled the OK return variable in the first condition.

exit=$returnSTateOK
