performing get: marshal: Unable to parse OID: strconv.ParseInt: parsing "iso": invalid syntax

I got the following error when I run telegraf with snmp filter

telegraf -config telegraf_snmp2.conf
2016/09/30 16:43:30 Starting Telegraf (version 1.0.0-beta3-136-gca8e512)

I used the same configuration on README.md
I running it over:
Ubuntu 16.04
Telegraf v1.0.0-beta3-136-gca8e512

The new database was created but without information
How can I fix it?

Can you show your configuration please?
The error means that you have telegraf configured to read an integer, but your snmp agent is returning a string.

The configuration file is this (available on https://github.com/influxdata/telegraf/tree/master/plugins/inputs/snmp)

[[inputs.snmp]]
  agents = [ "127.0.0.1:161" ]
  version = 2
  community = "public"
  name = "system"
  [[inputs.snmp.field]]
    name = "hostname"
    oid = ".1.0.0.1.1"
    is_tag = true
  [[inputs.snmp.field]]
    name = "uptime"
    oid = ".1.0.0.1.2"
  [[inputs.snmp.field]]
    name = "loadavg"
    oid = ".1.0.0.1.3"
    conversion = "float(2)"
  [[inputs.snmp.table]]
    name = "remote_servers"
    inherit_tags = [ "hostname" ]
    [[inputs.snmp.table.field]]
      name = "server"
      oid = ".1.0.0.0.1.1"
      is_tag = true
    [[inputs.snmp.table.field]]
      name = "connections"
      oid = ".1.0.0.0.1.2"
    [[inputs.snmp.table.field]]
      name = "latency"
      oid = ".1.0.0.0.1.3"
      conversion = "float"

I commented conversion lines to avoid the error, but the error persists.
I tried wih only uptime [inputs.snmp.field], but the error persists.
How can I solve it?

Found the issue here and fixed it. The issue is an incorrect handling of OIDs that can't be found in the MIB. Very easy fix. PR is up at #1846

[dragonxtek]

I update telegraf to this branch. Now, I don't receive errors, but also I don't receive any data to my influxdb :(

How I can add these fields to MIB? I need to download something?

[phemmer]

From your earlier comment, is sounds like you're using the sample config. This config is meant to demonstrate the usage of the plugin, and not actually be used. You have to generate a config specific to the device you're trying to probe.

Thanks, now it's working with snmp fields supported by my system and without errors

how did you solve this problem can you tell me
