Hello Alex,
here are my checkcommand definition and my service check definition :
define command{
command_name check_switchport_traffic
command_line $USER1$/check_iftraffic.pl -H $HOSTADDRESS$ -C
community -i $ARG1$ -b 100000000 -u=k
}
check_command check_switchport_traffic!port1
The only way to disable the embedded perl interpreter (Nagios 2) is to
recompile Nagios with the option '--disable-embedded-perl' or something
similar.
Frederik
