[collectd] Netlink plugin doesnt send if_octets-rx/tx

[קובי .]

Hi
I have collectd installed from source on ubuntu 12.04 with the netlink plugin .for some reason, i dont get the if_octets-rx and Tx from the interfaces , but only if_octets.my ubuntu is 12.04 and my collectd version is 4.10.9. , the interface im trying to monitor is eth1.11 (Vlan).here is my netlink config :
<Plugin netlink>        Interface "eth1.11"        VerboseInterface "eth1.11"        IgnoreSelected false</Plugin>
im all out of ideas , so if someone can help, that would be much appreciated .
Thanks !
