Hi, Thank you for your answer. No, I would like to filter more interfaces.
The idea is to examine a table an to filter the result. For example , filter the inteface mgmt but leave other.

I imagine you are going to need that. Its probably going to be dropped in to TypeInstance value whole like this TypeInstance "IF-MIB::ifName.526846912" again, just a guess - this is kinda new to me. I'm adding this back to the mailing list in case anyone else is more familiar. I haven't tried filtering, but if you only need data for a single interface, then it can be done without the filter; in the 'Data' definition within the snmp plugin config, just specify the OID+index in the 'Values' and set 'Table' to false, which will lead to only the data for that interface being pulled rather than the plugin parsing the ifTable. Assuming the index of that interface is 12345 on both chassis, something like: <Data "ifmib_if_octets32"> Type "if_octets" Table false Instance "te-0-1" Values "IF-MIB::ifInOctets.12345" "IF-MIB::ifOutOctets.12345" </Data> <Host "Nexus_5548_1"> Address "172.20.0.30" Version 2 Community "public" Collect "ifmib_if_octets32.12345" "ifmib_if_errors32.12345" Interval 120 </Host> <Host "Nexus_5548_2"> Address "172.20.0.31" Version 2 Community "public" Collect "ifmib_if_octets32.12345" "ifmib_if_errors32.12345" Interval 120 </Host> The instance will be appended to the value list, so in this example you'd end up with rrd filenames like 'ifmib_if_octets32-te-0-1', though you may also leave the instance blank. Cheers, -tt
