telegraf: telegraf 1.21.3 crashing: &GoSNMP.Conn is missing

Relevent telegraf.conf

# Telegraf Configuration
#
# Telegraf is entirely plugin driven. All metrics are gathered from the
# declared inputs, and sent to the declared outputs.
#
# Plugins must be declared in here to be active.
# To deactivate a plugin, comment out the name and any variables.
#
# Use 'telegraf -config telegraf.conf -test' to see what metrics a config
# file would generate.
#
# Environment variables can be used anywhere in this config file, simply prepend
# them with $. For strings the variable must be within quotes (ie, "$STR_VAR"),
# for numbers and booleans they should be plain (ie, $INT_VAR, $BOOL_VAR)


# Global tags can be specified here in key="value" format.
[global_tags]
  # dc = "us-east-1" # will tag all metrics with dc=us-east-1
  # rack = "1a"
  ## Environment variables can be used as tags, and throughout the config file
  # user = "$USER"


# Configuration for telegraf agent
[agent]
  ## Default data collection interval for all inputs
  interval = "60s"
  ## Rounds collection interval to 'interval'
  ## ie, if interval="10s" then always collect on :00, :10, :20, etc.
  round_interval = true

  ## Telegraf will send metrics to outputs in batches of at most
  ## metric_batch_size metrics.
  ## This controls the size of writes that Telegraf sends to output plugins.
  metric_batch_size = 1000

  ## For failed writes, telegraf will cache metric_buffer_limit metrics for each
  ## output, and will flush this buffer on a successful write. Oldest metrics
  ## are dropped first when this buffer fills.
  ## This buffer only fills when writes fail to output plugin(s).
  metric_buffer_limit = 10000

  ## Collection jitter is used to jitter the collection by a random amount.
  ## Each plugin will sleep for a random time within jitter before collecting.
  ## This can be used to avoid many plugins querying things like sysfs at the
  ## same time, which can have a measurable effect on the system.
  collection_jitter = "0s"

  ## Default flushing interval for all outputs. You shouldn't set this below
  ## interval. Maximum flush_interval will be flush_interval + flush_jitter
  flush_interval = "10s"
  ## Jitter the flush interval by a random amount. This is primarily to avoid
  ## large write spikes for users running a large number of telegraf instances.
  ## ie, a jitter of 5s and interval 10s means flushes will happen every 10-15s
  flush_jitter = "0s"

  ## By default or when set to "0s", precision will be set to the same
  ## timestamp order as the collection interval, with the maximum being 1s.
  ##   ie, when interval = "10s", precision will be "1s"
  ##       when interval = "250ms", precision will be "1ms"
  ## Precision will NOT be used for service inputs. It is up to each individual
  ## service input to set the timestamp at the appropriate precision.
  ## Valid time units are "ns", "us" (or "µs"), "ms", "s".
  precision = ""

  ## Logging configuration:
  ## Run telegraf with debug log messages.
  debug = false
  ## Run telegraf in quiet mode (error log messages only).
  quiet = false
  ## Specify the log file name. The empty string means to log to stderr.
  logfile = ""

  ## Override default hostname, if empty use os.Hostname()
  hostname = ""
  ## If set to true, do no set the "host" tag in the telegraf agent.
  omit_hostname = false

I’m going to reopen your original issue #10890, as this issue has a different root cause and is actually fixed.

Hipska on May 19, 2022

Hi @Hipska I can confirm: Version 1.22.4 is fixing the issue! https://github.com/influxdata/telegraf/releases/tag/v1.22.4

Thanks for your help!! 👍

BR/JO!

jostrasser on May 19, 2022

@jostrasser I think the following might as well help with your issue: #11042 I think you could try the latest nightly build.

Hipska on May 12, 2022

I just downgraded to 1.20.4 which is also for me the last good version. This made also my issue with one SNMP client go away.

I would report that in the respective PR…

Same here. Stuck between a rock and a hard place… Still getting the error &SNMP.Conn is missing with 1.22.1 on some oid’s, but if I roll back, then I am not able to resolve some other OID’s in 1.21.x which are working properly in 1.22.x…

yes, @jostrasser , confirmed. Stopping and starting again does not fix the “&GoSNMP.Conn is missing. Provide a connection or use Connect()” error. At least, Telegraf keeps running, which was not the case with 1.21.x.

Same here. Telegraf version 1.22, running on CentOS 8 stream. Lot of different SNMP input plugins stopped working after update to 1.22 with same error:

2022-04-06T08:10:03Z E! [inputs.snmp::Inventory] Error in plugin: agent 192.168.25.52:161: gathering table VRF_interface: performing bulk walk for field vrfIntType: &GoSNMP.Conn is missing. Provide a connection or use Connect()

Restarting Telegraf does not help.

Just to be clear, when having this issue, the issue remains until telegraf service is restarted? It doesn’t recover automatically after a while?

Yes, that’s correct. I have to manually restart the telegraf service afterward (or delaying the start). It is possible that the networking take some time to came up but it is strange that this only occurs on versions after 1.20.4.

No, it is not required, I just thought it would help me reproduce the issue. I will continue to try and get that error to pop up.

Thanks for your feedback and support! If you need additional informations or if I can do anything let me know.
