Hi,

the templates are working fine, i'm using the version 0.8.7i from Cacti.

today i'm finaly finished the nagios configuration. i'm using the check_snmp_oid command, available at exchange.nagios.com. thanks to BlackAbdula!
here is the device and service definiton for temperature monitoring:

define host{
    use         general-devices
    hostgroups  general-devices
    host_name   COMET T3511
    alias               Comet T3511
    address             192.168.5.36
}
define service{
        use                     generic-service
        host_name               COMET T3511
        service_description     Temperature
        check_command           check_snmp_oid!public!.1.3.6.1.4.1.22626.1.2.1.1.0!27!28
        }

and this is the command definition:

define command{
        command_name    check_snmp_oid
        command_line    $USER1$/check_snmp_oid -H $HOSTADDRESS$ -C $ARG1$ -o $ARG2$ -W $ARG3$ -M $ARG4$
        }
