Telegraf inputs.snmp.table not reporting entire table

Telegraf
1

Hi there, new Influx and Telegraf user here.

I’m having an issue with getting data from an SNMP table via Telegraf (inputs.snmp.table).
My query only ever returns one entry even though there are multiple entries expected.

My config looks like this…

[[inputs.snmp]]
  agents = [ "x.x.x.x"]
  version = 2
  community = "xxxxx"
  interval = "30s"
  timeout = "10s"   
  retries = 1
  max_repetitions = 20
  name = "aruba_mobility_master"

[[inputs.snmp.table]]
	  name = "SysXProcessorTable"
	  oid = "WLSX-SWITCH-MIB::wlsxSysXProcessorTable"

I’ve also tried specifying the individual table fields with “inputs.snmp.table.field” but I get the same result, just one entry (picks a random entry to write to Influx).

I’ve run snmpwalk and snmptable on this OID and it returns ALL of the expected data.
No “is this a table?” error or suchlike.

$ snmptable -v 2c -c xxxxx x.x.x.x WLSX-SWITCH-MIB::wlsxSysXProcessorTable
SNMP table: WLSX-SWITCH-MIB::wlsxSysXProcessorTable

      sysXProcessorDescr sysXProcessorLoad
     Supervisor Card CPU                 6
  Network Processor CPU9                 2

WLSX-SWITCH-MIB::sysXProcessorLoad.1 = INTEGER: 10
WLSX-SWITCH-MIB::sysXProcessorLoad.9 = INTEGER: 2
WLSX-SWITCH-MIB::sysXProcessorLoad.10 = INTEGER: 4
WLSX-SWITCH-MIB::sysXProcessorLoad.11 = INTEGER: 2
WLSX-SWITCH-MIB::sysXProcessorLoad.12 = INTEGER: 2
WLSX-SWITCH-MIB::sysXProcessorLoad.13 = INTEGER: 2
WLSX-SWITCH-MIB::sysXProcessorLoad.14 = INTEGER: 2
WLSX-SWITCH-MIB::sysXProcessorLoad.15 = INTEGER: 0

Telegraf reports no issue that I can see either. I’m running version 1.21.3

I’ve also tested the IF-MIB::ifTable and that works with the following code returning ALL the data for all the interfaces. It seems none of the private/Aruba tables want to work.

[[inputs.snmp.table]]
	  name = "InterfacesTable"
	  oid = "IF-MIB::ifTable"

I have run out of ideas and I’m hopeful that I’ve just done something silly or missed some thing.
Any help is greatly appreciated. Thank you.

Hi @MarcelV,
Welcome to the community! Hopefully, I can help get the debug process started and if we need to bring one of the Telegraf big guns in we will. Could you also use the file output plugin to send your data to a file? Something like this would do:

[[outputs.file]]
  ## Files to write to, "stdout" is a specially handled file.
  files = ["stdout", "/tmp/metrics.out"]
  data_format = "influx"

This will allow us to see what data is being read directly from Telegraf in line protocol format. If you wouldn’t mind posting the results of that here that would be brilliant.

Hi Jay

Thanks for the reply. I’ve run the output to file. I realise that I did this on a different table but the results are the same. Interestingly, if I read the output correctly it seems Telegraf is in fact reading the entire table but for some reason only 1 line appears in the InfluxDB. I’ve redacted some info and have not pasted the entire output. It’s pretty much 160 odd lines of the same then it loops again (I assume on the next query run).

Hi @MarcelV,
So sorry for the late reply I was at an event. So what It looks like is happening the timestamps are all the same which means the data is essentially overwriting itself within InfluxDB. What you could do is turn one of the fields into a tag to separate the data within InfluxDB. I will take your advice here on SNMP. Out of this data, you provided what would be a good describing field to separate the tables. I can then help you create a Telegrasf config

Hi @Jay_Clifford

No problem at all. Thanks for your time. I never even thought of that possibility as other tables
(mostly from MIB2) work just fine.

Anyway to answer your question - a potentially good field to tag would be the “wlanAPName” (1.3.6.1.4.1.14823.2.2.1.5.2.1.4.1.3) field as that is unique for each AP connected. Another possible option could be the “wlanAPIpAddress” field (1.3.6.1.4.1.14823.2.2.1.5.2.1.4.1.2).

Regards

Hi @MarcelV,
I am just tagging @Hipska here. He is one of our Telegraf maintainers and regularly uses SNMP. He will be able to help advise on the best way to tag your data. wlanAPName sounds okay but my main concern there would be cardinality if the list keeps growing :slight_smile: .

7

The easiest way to do and go forward would be setting index_as_tag = true in the table.

According to the MIB, the index should be sysXProcessorID, but that doesn’t seem to be available. So what I would do is adding this to the config:

    [[inputs.snmp.table.field]]
      oid = "WLSX-SWITCH-MIB::sysXProcessorDescr"
      is_tag = true
8

Thanks, @Hipska - I read that adding in specific fields from a table would then only return those fields and not the whole table, does that mean I should add all the fields I’m interested to see?

In the meantime I will give the is_tag and even the index_as_tag a try. Thanks for that.

9

That would only be the case if you omit the oid setting from the table config. So, if you keep that, all will stay the same and you will get that description field as tag instead…

10

Got it.

Well I can confirm the “tagging” has solved my problem. Can not thank you enough!
Please consider my issue resolved and thanks again for the help @Jay_Clifford and @Hipska
