Is this an issue with Telegraf/Influx or Grafana?

[g0nz0uk]

Hello,

Why can’t I get the ‘agent_host’ to show in Grafana, it does on other Grafana, Influx, Telegraf setups I’ve used in the past.

Is it me?

My telegraf file: (I’ve altered some of the info for the post due to sensitivity)

 [[inputs.snmp]]
  agents = [ "10.100.32.69:161" ]
  version = 2
  community = "password"

  [inputs.snmp.tags]
    locationd12 = "Big Street "

  [[inputs.snmp.field]]
    name = "d6-hostname"
    oid = "1.3.6.1.2.1.1.5.0"

  [[inputs.snmp.field]]
    name = "d6-uptime"
    oid = "1.3.6.1.2.1.25.1.1.0"

  [[inputs.snmp.field]]
    name = "d6-cpu1"
    oid = "1.3.6.1.2.1.25.3.3.1.2.1"

  [[inputs.snmp.field]]
    name = "d6-cpu2"
    oid = "1.3.6.1.2.1.25.3.3.1.2.2"

  [[inputs.snmp.field]]
    name = "d6-cpu3"
    oid = "1.3.6.1.2.1.25.3.3.1.2.3"

  [[inputs.snmp.field]]
    name = "d6-cpu4"
    oid = "1.3.6.1.2.1.25.3.3.1.2.4"

  [[inputs.snmp.field]]
    name = "d6-cpu5"
    oid = "1.3.6.1.2.1.25.3.3.1.2.5"

  [[inputs.snmp.field]]
    name = "d6-cpu6"
    oid = "1.3.6.1.2.1.25.3.3.1.2.6"

  [[inputs.snmp.field]]
    name = "d6-cpu7"
    oid = "1.3.6.1.2.1.25.3.3.1.2.7"

  [[inputs.snmp.field]]
    name = "d6-cpu8"
    oid = "1.3.6.1.2.1.25.3.3.1.2.8"

What I see when I test:

sudo telegraf --test -config test.conf 
2021-11-05T11:01:39Z I! Starting Telegraf 1.20.3
> snmp,agent_host=10.10.32.69,host=svr-grafana,locationd12=Big\ Street\  d6-cpu4=33i,d6-cpu5=18i,d6-cpu6=21i,d6-cpu7=18i,d6-hostname="NS1-T01",d6-uptime=72835823i 1636110100000000000

What the DB shows:

Chronograf:

Here I can’t see the ‘agent_host’ IP

Grafana:

My DB has a username and password on but in Grafana you can add the DB with not username and password and it allows it, that can’t be right?

Usually I’d find the IP in the drop down, but it finds nothing:

If I manually put the IP in and choose the fields it finds data.

I’ve always managed to get the drop down to show all the IPs that are configured in the telegraf .conf file but not anymore, I’ve tried influx, telegraf and Grafana on a new VM too and it does the same.

Same with the tag:

If I manually type it in it works:

This also stops Variables working in Grafana if I start adding 100s ip IPs.

What do you think is going wrong here?

This is a working setup I’ve used elsewhere as you can see the dropdown for the ‘agent_host’ is pre-populated as it’s pulling from Influx:

Any help would be great.

Thanks

@g0nz0uk

it does on other Grafana, Influx, Telegraf setups I’ve used in the past.

what Grafana version where you using then?
what Grafana version are you using now?

I would also check the network tab of your browser’s dev tools when you try to save and test the datasource. Something looks off there…

How do I check the network tab? I’m not sure I’ve seen this.

here is a great rundown on user Chrome’s dev tools to inspect network activity:
