Connecting The Things Network and InfluxDb with MQTT and Telegraf

As the title shows, I am trying to connect The Things Network and Influx but i am really unprepared and I am encountering a lot of trouble.
At first none of the guides I followed worked, then I found one that seemed to work but the results are unexpected: telegraf is connected to the source of data but no data enters the database.

I don’t understand why its not working,
Thank you kindly for your help.

Hello @Hircus,
can you please set
under the agent part of your config? and share the logs?
Thank you.

Thank you for your time, here’s the log with the image:

This buffer fullness message indicates that there is nothing to send. Can you share what it looks like on the Things Network side?

Here’s a blog on how to connect to the Things Network. If you go down to the “Getting it into InfluxDB” that’s where it addresses the Telegraf portion.
