Question about open ports in Telegraf

[MagicPupu]

Hello,

I am planning to deploy Telegraf in an on-premises environment, and I have noticed that the following ports are open by default:

• 8125 UDP
• 8092 UDP
• 8094 TCP

However, I couldn't find clear documentation or explanations regarding the purpose of these ports. Could you provide more information on why they are open, what services or features are utilizing them, and if they are necessary for all deployments? I need to ensure the security and proper configuration of these ports for my specific use case.

Thank you in advance for your help!

Best regards,
Antoine

My guess.

8125 UDP
StatsD plugin?

8092 UDP
Changed default port to 8092, this was to fit in more with other TICK stack things (InfluxDB uses 8090 by default for udp, Kapacitor uses 9092). I also didn't want the default to conflict with the statsd default.

8094 TCP
Receiving HTTP-based Metric?
