Hi,
It's ok,
Example for my nexus 5000
Filter
LoadPlugin "match_regex"
#LoadPlugin "target_notification"
<Chain "PreCache">
<Rule>
<Match "regex">
host "^Nexus_5548_1"
Plugin "snmp"
TypeInstance "^Ethernet10[1-2]_1_(([5-9]?$)|([1-3][0-9]$))"
</Match>
# for debug see the file /var/log/collectd.conf
# <Target "notification">
# Message "Instance %{type_instance} !"
# Severity "WARNING"
# </Target>
Target "stop"
</Rule>
</Chain>

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.
Cordially,

Type is probably going to be your IF-MIB::ifOctets.526846912
Do you know how to find the interface index?
$ snmpwalk -v2c -c foo_comm_string foo_host IF-MIB::ifName
IF-MIB::ifName.526846656 = STRING: Ethernet104/1/44
IF-MIB::ifName.526846720 = STRING: Ethernet104/1/45
IF-MIB::ifName.526846784 = STRING: Ethernet104/1/46
IF-MIB::ifName.526846848 = STRING: Ethernet104/1/47
IF-MIB::ifName.526846912 = STRING: Ethernet104/1/48
(...)
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
