Check_interfaces: Display bandwith in graphite?

Hi together,

i have a question for the plugin plugin check_interfaces from NETWAY’s: https://github.com/NETWAYS/check_interfaces

First, i create a new Service-Template with the following command:

’/usr/lib64/nagios/plugins/check_interfaces’ ‘–community’ ‘XXXX’ ‘–hostname’ ‘172.xx.xx.xx’ ‘–lastcheck’ '$service.last_check$ ‘–perfdata’ '$service.perfdata$ ‘–regex’ '^1$'

In Icinga2, i can see, that the bandwith is display correctly:

My problem now is, how can I display the bandwith in a graphite graph? Under the perfomance data no bandwith displayed.

Thank your for any help!
