pppoe interface stopped monitoring

[Brano]

Hi.

I have Zabbix 2.4.5 running for some time and was successfully monitoring Ubiquiti ER3-Lite router's interfaces, including WAN interface which is PPPoE.

After ISP connectivity loss, modem was rebooted thus pppoe0 was dropped and re-negotiated. Since that moment Zabbix is showing empty graphs for this pppoe0 interface with errors "No Such Instance currently exists at this OID"

When doing manual snmpwalk I still see the pppoe0 interface listed

brano@rpi2 ~ $ snmpwalk -v 2c -c public 10.10.10.1 | grep "pppoe"
HOST-RESOURCES-MIB::hrSWRunParameters.1997 = STRING: "call pppoe0"
HOST-RESOURCES-MIB::hrSWInstalledName.242 = STRING: "pppoe-1:3.11-ubnt4+t4688590"
HOST-RESOURCES-MIB::hrSWInstalledName.280 = STRING: "ubnt-pppoe-server-0.1.10+t4776181"
HOST-RESOURCES-MIB::hrSWInstalledName.297 = STRING: "vyatta-cfg-op-pppoe-1:0.12.9+t4797463"
IF-MIB::ifAlias.15 = STRING: pppoe0

The last message Zabbix threw on this was "The operational status was changed on router interface ppppo0" ... since then I see blank graphs.

Any ideas how to fix this and get the interface back to monitoring status?

EDIT: It turns out it's a bug on the router. Case closed

Hi it seems to be a problem related to the OIDs that change every time pppoe-interface connection from client restarts..
