I am sure I am overlooking a small detail but for some reason as soon as I add the section below to my configuration the service fails to start.
# Interface tag - used to identify interface in metrics database
[[inputs.snmp.table.field]]
name = "ifDescr"
oid = "IF-MIB::ifDescr.1"
Here’s my complete working config:
[[inputs.snmp]]
agents = [ "192.168.139.50:161" ]
# ## Timeout for each SNMP query.
timeout = "5s"
# ## Number of retries to attempt within timeout.
retries = 3
# ## SNMP version, values can be 1, 2, or 3
version = 2
#
# ## SNMP community string.
community = "public"
#
# ## The GETBULK max-repetitions parameter
max_repetitions = 10
#
# ## measurement name
name = "unifi_UAP"
[[inputs.snmp.field]]
name = "sysUpTime"
oid = ".1.3.6.1.4.1.41112.1.6.3.5.0"

@daniel That helped and now the service will start. Unfortunately I am greeted with:
Error in plugin [inputs.snmp]: initializing table unifi: initializing field ifDescr: translating: exec: "snmptranslate": executable file not found in $PATH
When using OID textual names, you will need the snmptranslate and snmptable commands in your environment. Usually you can get these with apt-get install snmp.
Let me try and explain better (should of done that since the beginning, I apologize).
Here’s is my working configuration prior to the error:
[[inputs.snmp]]
agents = [ "IP:161" ]
# ## Timeout for each SNMP query.
timeout = "5s"
# ## Number of retries to attempt within timeout.
retries = 3
# ## SNMP version, values can be 1, 2, or 3
version = 2
#
# ## SNMP community string.
community = "Public"
#
# ## The GETBULK max-repetitions parameter
max_repetitions = 10
name = "esxi"
[[inputs.snmp.field]]
name = "esxi-memory-used"
oid = ".1.3.6.1.2.1.25.2.3.1.6.5"
[[inputs.snmp.field]]
name = "esxi-memory-available"
oid = ".1.3.6.1.2.1.25.2.2.0"
[[inputs.snmp.field]]
name = "esxi-uptime"
oid = ".1.3.6.1.2.1.25.1.1.0"
[[inputs.snmp.field]]
name = "esxi-cpuload1"
oid = ".1.3.6.1.2.1.25.3.3.1.2.1"
[[inputs.snmp.field]]
name = "esxi-cpuload2"
oid = "..1.3.6.1.2.1.25.3.3.1.2.2"
[[inputs.snmp.field]]
name = "esxi-cpuload3"
oid = ".1.3.6.1.2.1.25.3.3.1.2.3"
[[inputs.snmp.field]]
name = "esxi-cpuload4"
oid = ".1.3.6.1.2.1.25.3.3.1.2.4"
[[inputs.snmp.field]]
name = "esxi-cpuload5"
oid = ".1.3.6.1.2.1.25.3.3.1.2.5"
[[inputs.snmp.field]]
name = "esxi-cpuload6"
oid = ".1.3.6.1.2.1.25.3.3.1.2.6"
Then, I tried adding another configuration for my router:
[[inputs.snmp]]
agents = [ "IP:161" ]
# ## Timeout for each SNMP query.
timeout = "5s"
# ## Number of retries to attempt within timeout.
retries = 3
# ## SNMP version, values can be 1, 2, or 3
version = 1
#
# ## SNMP community string.
community = "Public"
#
# ## The GETBULK max-repetitions parameter
max_repetitions = 10
#
[[inputs.snmp.field]]
name = "hostname"
oid = "RFC1213-MIB::sysName.0"
is_tag = true
[[inputs.snmp.table]]
name = "snmp"
inherit_tags = [ "hostname" ]
[[inputs.snmp.table.field]]
name = "ifDescr"
oid = "IF-MIB::ifDescr"
is_tag = true
[[inputs.snmp.table.field]]
name = "ifInOctets"
oid = "IF-MIB::ifInOctets"
[[inputs.snmp.table.field]]
name = "ifOutOctets"
oid = "IF-MIB::ifOutOctets"
But that results in the error I originally posted. You suggested I install snmp and after doing so I get this when I try the command telegraf snmptranslate --help:
telegraf snmptranslate --help

In the original config, there is a line: oid = "..1.3.6.1.2.1.25.3.3.1.2.2", can you remove one of the leading dots so you have oid = ".1.3.6.1.2.1.25.3.3.1.2.2".
@daniel After a quick google search, I discovered that I needed to sudo apt-get install snmp-mibs-downloader and sudo download-mibs. I am sure you were about to tell me to do that anyways!
Now everything works great!
Thank you very much for your prompt responses. I really appreciate it!
I am trying to collect snmp data from several sources using Telegraf
however I am getting the same error
When I try to install snmp-mibs-downloader it keeps telling me the package is not available. I have tried adding to the sources.list and updating but nothing works.
This package is only in the non-free section of the Debian repo, perhaps you need to enable it? Here is a Debian example but it should be pretty similar:
deb http://ftp.us.debian.org/debian/ stretch main contrib non-free
Thanks for the input. Sorry but your solution didn’t work. However I have solved the problem and Telegraf is now up and running. Just in case anyone else has the same issue this is what I did (not an elegant solution but it worked!).
I am using an old small form factor 32bit machine as its only job is telegraf.
1/ Went back to ubuntu 16.04 -i386 installed and fully updated.
2/ Found snmp-mibs-downloader_1.2_all.deb installed it manually and updated the MIBs files.
3/ Found snmp_5.7.2_dfsg-8.1 ubuntu3.3_i386.deb and installed it manually.
4/ Installed Influx repository and Telegraf.
5/ update telegraf.conf and restarted.
