Well, *something* needs to submit the status change to nagios. For your specific example of the switch port, I'm certain the switch doesn't talk the NSCA protocol but it may be able to send SNMP traps. If it can, you can use SNMPTT (or similar) to receive those traps and submit them to Nagios in real time. See the nagios documentation on SNMP Traps. If your switch or device isn't able to send SNMP traps then your only other options are to find something that it _can_ do in Real Time and work something up around that or to perform your current check more frequently. -- Marc ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
