SNMP recovery problem

Telegraf
1

I am recovering data from olt zte, and I have problems because it has double or secondary indexes… I provide a zabbix template and how to recover them but in telegraf I can not do that
discovery_rules:

uuid: b612951f77ec4ceb81eb30423637ee43
name: ‘ONU discovery on pon1’
type: SNMP_AGENT

203 / 5,000

my oid to recover the data is 1.3.6.1.4.1.3902.1012.3.50.12.1.1.10 but I see that zabbix uses .3.6.1.4.1.3902.1012.3.50.12.1.1.10.268501248.{#SNMPINDEX}.1 with telegraf I can not recover that way

@Carlos_Segala currently there is (almost) no discovery mechanism for configuring plugins. So you need to discover the devices in some other way and generate the telegraf configuration using e.g. a small python program with a templating engine…

3

And also, if you define an [[inputs.snmp.table]], then all the rows of that table will be gathered by default…

4

My table is [[inputs.snmp.table]] name = “onu” oid = “1.3.6.1.4.1.3902.1012.3.50.12.1” index_as_tag = true but it gives me this error in telegraf [telegraf] Error running agent: could not initialize input inputs.snmp: initializing table un: getting table columns: Was that a table? ZXXPON-PROTECTION-MIB::zxPON.3.50.12.1: exit status 1

5

You don’t seem to have the MIB to translate the OID or to figure out the fields on that table. You can add the fields manually (which is preferable if you don’t need all the fields of the table)

6

Does anyone have the GPON-PROTECTION-MIB because otherwise I can’t get the double index of my ONT something like 269550336.54.1
Thanks

7

You don’t need the MIB, you can also specify the fields you want manually and specify the OID numerically.

8

I’ll send you my config to see if you can help me. When I do it via console on the command line it works fine, but then in my telegraf file it doesn’t recover the ont_rx data, so I’ve been investigating in some scripts that I saw that add a .1 to the oid at the end of the index. In the examples I saw they treat it this way .1.3.6.1.4.1.3902.1012.3.50.12.1.1.14.{index}.1 and from what I see in telegraf it’s taking me .1.3.6.1.4.1.3902.1012.3.50.12.1.1.14.{index} without the .1 maybe that’s it but I’m not sure.
via console

[[inputs.snmp]]

It is a separate table, so must be defined as such in telegraf as well:

[[inputs.snmp.table]]
  name = "something"
  index_as_tag = true

[[inputs.snmp.table.field]]
  name = "ont_rx"
  oid = “1.3.6.1.4.1.3902.1012.3.50.12.1.1.14”
10

Yes, I tried it like that once and it didn’t work for me - in fact, I just tried it again that way, but it only shows me the data from the previous fields but not that one, I don’t understand why it doesn’t show them to me -
Maybe it’s because that oid queries the onts that are connected to an olt and maybe it takes longer than the oids of the main equipment. But I added a timeout = “300s” but it didn’t work for me either.

11

Can you show the output of that table when running telegraf --test? and please use code blocks so everything keeps being readable…

12

if the current configuration and the output go there
[[inputs.snmp]]
agents = [“172.20.0.2:161”]
version = 2
community = “public”
interval = “900s”
name = “olt”

[[inputs.snmp.table]]
name = “olt”
oid = “IF-MIB::ifXTable”
index_as_tag = true

[[inputs.snmp.table.field]]
name = “ifNombre”
oid = “IF-MIB::ifName”
is_tag = true

[[inputs.snmp.table.field]]
name = “ifIndex”
oid = “IF-MIB::ifIndex”
is_tag = true

[[inputs.snmp.table]]
name = “ont”
index_as_tag = true

[[inputs.snmp.table.field]]
name = “ont_rx”
oid = “1.3.6.1.4.1.3902.1012.3.50.12.1.1.14”

13

:point_up: please see this and adapt your last post.

Maybe also add --debug as it seems the ont metrics aren’t collected…

Not sure if that will change anything, but you’re using version 1.28.2, which is from last year.

I think we will need to do a tcpdump to see what telegraf is sending and/or receiving. But please remove the olt table first, as that will give a lot of irrelevant data.

16

The version is not because I’m running 1.31.3 on another server and it does the same thing…
I’m suspicious of the host that may not be able to respond to requests or something like that… because at one point with the configuration that I gave you it brought me some data but only from approximately 10% of the devices
