SNMP Plugin development

[PaoloBacco]

Hy all community members,
I started new SNMP plug-in for Acme Packed SBC.
This device exposes both standard mibs (IF-Mib, IP-MIB) and custom mibs.
I'd like to develop my plug-in as an extension of network device plug-in in order to collect ip metrics by some including tag like &netdevice-platform and discover interfaces as hyperic services by '&netdevice-services'.
I guess that some way I should include /etc/netdevice-platform.xml and /etc/netdevice-platform.xml /etc/netdevice-services.xml files as it was done with Cisco based plug-in, but import doesn't work .
Some tips?
Thanks,
Paolo Bacco
