input: snmp with subtables

[grisu-cl]

Hi,

i just go a strange result when using subtables

config1:

[[inputs.snmp.host]]
    address = "vie-sw1:161"
[[inputs.snmp.host.table]]
      name = "iftable"
[[inputs.snmp.table]]
    name = iftable"
    oid = ".1.3.6.1.2.1.2.2.1.10"
    mapping_table = ".1.3.6.1.2.1.31.1.1.1.1"  # ifname

and the output looks like expected:

 Plugin: snmp, Collection 1
* Internal: 30s
> ifInOctets,host=vie-sw1,instance=g1 ifInOctets=0i 1461877530443457065
> ifInOctets,host=vie-sw1,instance=g2 ifInOctets=0i 1461877530443672186
> ifInOctets,host=vie-sw1,instance=g3 ifInOctets=96614124i 1461877530443736317
> ifInOctets,host=vie-sw1,instance=g4 ifInOctets=313296936i 1461877530443765621
> ifInOctets,host=vie-sw1,instance=g5 ifInOctets=445335367i 1461877530443796753

if i change the config to:

  [[inputs.snmp.table]]
    name = "iftable"
    mapping_table = ".1.3.6.1.2.1.31.1.1.1.1"
    sub_tables=[".1.3.6.1.2.1.2.2.1.10"]

i got a strange output like this:

as i understand the 2 config should be equal
also if i use oid=".1.3.6.1.2.1.2.2.1" the output is ok (but i dont i dont want all subtables)

any ideas?

the switch is a cisco sge2000 ....

[sparrc]

@titilambert another SNMP one :-), see anything obvious?

[grisu-cl]

yes, there is a obvious thing ... if i am adding
include_instances = ["g1", "g10"]

it shows:

* Plugin: snmp, Collection 1
* Internal: 30s
> ifInOctets,host=vie-sw1,instance=g1 ifInOctets=0i 1461916847966013700
> ifInOctets,host=vie-sw1,instance=g1 ifInOctets=2119761526i 1461916847966128160

the snmp-response for ifName looks like that, so it is ok

data: get-response (2)
    get-response
        request-id: -1635893253
        error-status: noError (0)
        error-index: 0
        variable-bindings: 32 items
            1.3.6.1.2.1.31.1.1.1.1.1: 6731
                Object Name: 1.3.6.1.2.1.31.1.1.1.1.1 (iso.3.6.1.2.1.31.1.1.1.1.1)
                Value (OctetString): 6731
            .....
            1.3.6.1.2.1.31.1.1.1.1.10: 673130
                Object Name: 1.3.6.1.2.1.31.1.1.1.1.10 (iso.3.6.1.2.1.31.1.1.1.1.10)
                Value (OctetString): 673130

and thats the data response for ifInOctets

    data: get-response (2)
        get-response
            request-id: -283694755

short update:

in a self-compiled version this error does not occur

# ~/work/bin/telegraf version
Telegraf - Version 0.12.1-97-g4c28f15

[sparrc]

which version were you using in the first case?

[sparrc]

it's possible that this pr fixed your issue? #1044

[titilambert]

@sparrc you're right, it seems related to #1044
@grisu-cl your self-compiled version does include #1044 ?

[sparrc]

version 0.12.1-97-g4c28f15 would contain #1044, closing this as fixed by #1044
