Nagios is checking this using the nrpe plugin but only as information. Can anybody tell me if there is any plugin out there or any ideas to have Nagios check this script and would report to be critical if a "user" or an "account" is not currently log in and "OK" state if a "user" is currently log in. Any help is greatly appreciated.... Thanks, RFA</DIV></BODY></HTML>
