Hi,

I'm using config with mapping and subtables as example 'iftable4':

[[inputs.snmp]]
  snmptranslate_file = "/tmp/oids.txt"
  [[inputs.snmp.host]]
    address = "127.0.0.1:161"
    community = "public" # default public
    version = 2 # default 2
    [[inputs.snmp.host.table]]
      name = "iftable4"
      include_instances = ["eth0"]

  [[inputs.snmp.table]]
    name = "iftable4"
    mapping_table = ".1.3.6.1.2.1.31.1.1.1.1"
    sub_tables=[".1.3.6.1.2.1.2.2.1.13", "bytes_recv", "bytes_send"]

  [[plugins.snmp.subtable]]
    name = "bytes_recv"
    oid = ".1.3.6.1.2.1.31.1.1.1.6"
    unit = "octets"

  [[plugins.snmp.subtable]]
    name = "bytes_send"
    oid = ".1.3.6.1.2.1.31.1.1.1.10"
    unit = "octets"

I have:

~# /usr/bin/telegraf -config /etc/telegraf/telegraf.conf -config-directory /etc/telegraf/telegraf.d/ -test -debug
* Plugin: snmp, Collection 1
2016/03/17 15:19:09 marshal: Unable to parse OID: strconv.ParseInt: parsing "bytes_recv": invalid syntax

snmp is working on localhost:

~# snmpwalk -v2c -c public localhost .1.3.6.1.2.1.31.1.1.1.1
iso.3.6.1.2.1.31.1.1.1.1.1 = STRING: "lo"
iso.3.6.1.2.1.31.1.1.1.1.2 = STRING: "eth0"

I have the issue with an existing ifname 'eth0' here. If I set a name which does not exist, it returns nothing but it doesn't crash.

I'm using latest available version: 0.11.1

Regards
Guillaume

Hi,

May I do a little "UP" ?

Seriously, did you have any time to check what's happen ?

@glz-io Sorry for the delay :/
I don't get an error :/ Could you create a gist with your /tmp/oids.txt file ?
Thanks !

I have similar case.
Config file:

[[inputs.snmp]]
  snmptranslate_file = "/etc/telegraf/oids.txt"
  [[inputs.snmp.host]]
    address = "127.0.0.1:161"
    community = "public" # default public
    version = 2 # default 2
    collect = ["interface_speed", "if_number", "if_out_octets"]

  [[inputs.snmp.get]]
    name = "interface_speed"
    oid = "ifSpeed"
    instance = "1"

  [[inputs.snmp.get]]
    name = "if_number"
    oid = "ifNumber"

  [[inputs.snmp.bulk]]
    name = "if_out_octets"
    oid = "ifOutOctets"

/etc/telegraf/oids.txt:

Error message:

@glz-io @r0bj Could you confirm that you have an output like this:

@r0bj @glz-io In fact there are 2 bugs ! :D

I'm looking for the next one ...

@glz-io I found it !
This is a documentation error ...
You don't have to use "plugins.snmp.subtable" but "inputs.snmp.subtable" ...
I will make a PR to fix it.

@titilambert Ok I do not have the error message after changing "plugins" to "inputs".

But it still does not work. Due to the other bug ?

There is SNMP traffic to the telegraf:
https://gist.github.com/r0bj/2b1fc7aadbb98a95fb82

Result is empty:

telegraf -config /etc/telegraf/telegraf.conf -test

I have exactly the same behavior.
snmpwalk is ok, I can see trafic with tcpdump by telegraf, but I have no result.

@glz-io @r0bj Try to replace all spaces by tabs in oids.txt file

cp oids.txt oids.txt.back

@titilambert this is working !
Thx

But in fact, I've created oids.txt with the command in documentation.

@glz-io Yeah, this is the bug.. I fix a regex in the code... I don't know why I didn't see this error before ...

I've seen the regexp change in the diff.

It seems fixed for me at the moment.

thx a lot.
