Start the daemon monitor by running ./throughput.rb
* You can change the port the daemon runs on by changing the "port" settings at the top of the file. This file will run continuously.
Use the "check_throughput" file as the Nagios checker. In the Nagios commands file, put the following:
define command {
command_name check_throughput
command_line /usr/lib/nagios/plugins/check_throughput $HOSTADDRESS$ $ARG5$ $ARG4$ $ARG1$ $ARG2$ $ARG3$
}
define service{
use standard
host_name my-rtr
service_description IN THROUGHPUT
check_command check_throughput!10!2400:-1!2800:-1!in!public
notifications_enabled 0
}
Where the following arguments are the settings:
HOSTADDRESS = ip address of the router / switch
ARG1 = SNMP device number -- get this with snmpwalk
ARG2 = the "OKAY" range, outside this range will generate a warning
ARG3 = the "warning" range, outside this range will be critical
ARG4 = the direction of traffic (in|out)
ARG5 = SNMP community string (usually default to "public")
