Telegraf not send metrics in Influxdb and Grafana!

Next_generation · September 8, 2021, 12:04pm

Hello!
I need just snmp, snmp.traps monitoring unifi switches UP/DOWN status and drawing graphs on this data in grafana and send alert based it
I have 3 docker containers:

telegraf
influxdb 1.8
grafana

I have 30 switches and 7 AP and need monitoring it with SNMP v3
Please help correct the config and detail reply how to fix this issue
I am trying snmpwalk v3 test manually for unifi switches on a remote host, it works inside a docker container.

But unfortunately my configuration not working:

/etc/telegraf/telegraf.conf

[global_tags]
[agent]
interval = “10s”
round_interval = true
metric_batch_size = 1000

*# Transport, local address, and port to listen on. *

#Transport must be “udp: //”. Omit local address to listen on all interfaces.*

telegraf --input-filter snmp --test

Giovanni_Luisotto · September 9, 2021, 12:24pm

as per error message you have something invalid at line 15

{.....}
[outputs.influxdb]]

in this case it’s a missing square bracket [[outputs.influxdb]]

Thank, Giovanni_Luisotto I fixed, but metrics don’t input in influxdb…I not have ideas.
Maybe need add firewall exeption or docker containers must be in one subnet, I don’t know

Giovanni_Luisotto · September 12, 2021, 8:38pm

have a look at the telegraf logs, to find what’s going on, or use the command:
telegraf --input-filter snmp --once

--test does not run outputs, therefore you won’t see errors related to them, --once runs the whole pipeline just once

it feels like there is no connection with the base which is in a separate dock container because the metrics are not written

Giovanni_Luisotto · September 14, 2021, 7:30am

have you had a look at your log file /var/log/telegraf/telegraf.log ?
Whatever happens will be written in there, and if you got no data in the database I expect to find some errors.

Sorry but I don’t know much about the inputs.snmp and snmp, I doubt I can help you further.

Your issue is a known one looks like, as I had a look around and found some related issues:
