I'm trying to set-up monitoring on our routers in which I already followed this doc: <a target="_blank" href="http://nagios.sourceforge.net/docs/3_0/monitoring-routers.html">http://nagios.sourceforge.net/docs/3_0/monitoring-routers.html</a> I'm doing snmp at this point and trying to define the service to my hosts then I get this error when verifying: Error: Service check command 'check_snmp' specified in service 'PING-NET' for host 'cisco-router' not defined anywhere! Here's a sample of my cfg: define service{ &nbsp ; use local-service ; Inherit values from a template host_name cisco-router ; The name of the host the service is associated with service_description PING-NET &nbs p; ; The service description check_command check_snmp!-C public -o sysUpTime.0 ; The command used to monitor the service normal_check_interval 5 ; Check the service every 5 minutes under normal conditions retry_check_interval 1 ; Re -check the service every minute until its final/hard state is determined } Any ideas? Need expert advise please. Thank you! </div> </body></html>
