Problem with Telegraf and oid istance

Telegraf
1

Hello, sorry for the dumb question but I’m experiencing a collect problem with Telegraf.
I’m trying to collect SNMP data from a QNAP NAS, so far I’m able to collect “single” datas like RAM or CPU etc, however if I try to set an oid with an istance like disk number it doesn’t work at all.

I’ll post you a little example:

[[inputs.snmp.table.field]]
name = "HDD1_Temp"
oid = “1.3.6.1.4.1.24681.1.4.1.1.1.1.5.2.1.6.1”

[[inputs.snmp.table.field]]
name = "HDD2_Temp"
oid = “1.3.6.1.4.1.24681.1.4.1.1.1.1.5.2.1.6.2”

[[inputs.snmp.table.field]]
name = "HDD3_Temp"
oid = “1.3.6.1.4.1.24681.1.4.1.1.1.1.5.2.1.6.3”

[[inputs.snmp.table.field]]
name = "HDD4_Temp"
oid = “1.3.6.1.4.1.24681.1.4.1.1.1.1.5.2.1.6.4”

The last digit should be the istance, but is not collecting any data. If I remove the last digit I can gather the temp from the first HDD.
I’m sure I’m doing something wrong, but I couldn’t find any good explaination so I decided to post here.

Thanks in advance for your time

Can you share the entire snmp config, without any credentials of course. Also check what this command returns (probably need to change the connection settings:

snmptable -v2c -c public localhost:161 .1.3.6.1.4.1.24681.1.4.1.1.1.1.5.2.1.6

Thanks for helping me, here you go:

[global_tags]
[agent]
interval = “10s”
round_interval = true
metric_batch_size = 1000
metric_buffer_limit = 10000
collection_jitter = “0s”
flush_interval = “10s”
flush_jitter = “0s”
precision = “”
debug = false
quiet = false
logfile = “”
hostname = “”
omit_hostname = false
[[outputs.influxdb]]
urls = [“http://localhost:8086”] # required
database = “telegraf” # required
retention_policy = “”
write_consistency = “any”
timeout = “5s”
[[inputs.cpu]]
percpu = true
totalcpu = true
collect_cpu_time = false

[[inputs.diskio]]
[[inputs.kernel]]
[[inputs.mem]]
[[inputs.processes]]
[[inputs.swap]]
[[inputs.system]]
[[inputs.snmp]]
agents = [ “192.168.1.10:161” ]
timeout = “5s”
retries = 3
version = 2
community = “public”
max_repetitions = 10

[[inputs.snmp.table]]
name = “remote_servers”

[[inputs.snmp.table.field]]
name = “Fan_Speed”
oid = “1.3.6.1.4.1.24681.1.3.15.1.3”

[[inputs.snmp.table.field]]
name = “CPU_Load”
oid = “1.3.6.1.4.1.24681.1.3.1”

[[inputs.snmp.table.field]]
name = “CPU_Temp”
oid = “1.3.6.1.4.1.24681.1.3.5”

[[inputs.snmp.table.field]]
name = “System_Temp”
oid = “1.3.6.1.4.1.24681.1.3.6”

[[inputs.snmp.table.field]]
name = “Total_RAM”
oid = “1.3.6.1.4.1.24681.1.3.2”

[[inputs.snmp.table.field]]
name = “Free_RAM”
oid = “1.3.6.1.4.1.24681.1.3.3”

[[inputs.snmp.table.field]]
name = “HDD1_Temp”
oid = “1.3.6.1.4.1.24681.1.4.1.1.1.1.5.2.1.6”

[[inputs.snmp.table.field]]
name = “HDD2_Temp”
oid = “1.3.6.1.4.1.24681.1.4.1.1.1.1.5.2.1.6”

[[inputs.snmp.table.field]]
name = “HDD3_Temp”
oid = “1.3.6.1.4.1.24681.1.4.1.1.1.1.5.2.1.6”

[[inputs.snmp.table.field]]
name = “HDD4_Temp”
oid = “1.3.6.1.4.1.24681.1.4.1.1.1.1.5.2.1.6”

With this configuration I’m able to see the first HDD Temp, if I add at the end of the oid the istance it no longer works…

And the command output is:
Was that a table? iso.3.6.1.4.1.24681.1.4.1.1.1.1.5.2.1.6

Thanks again

Try adding a field that will provide a tag, such as:

  [[inputs.snmp.field]]
    name = "hostname"
    oid = "RFC1213-MIB::sysName.0"
    is_tag = true

With this configuration the OID istances are recognized.
