@glimchb can you help me add this syslog telemetry I am trying to forward the message using TCP and tried multiple ways but not work, I have read many things but have not been able to fix this. I have also tried to use UDP but won't work.

@glimchb will it be fine if I create my own image and use it here. I am still unsure why data is not collected by telegraf from rsyslog image. I can use Ubuntu as base image and do the setup of rsyslog on that to gather data and serve it, I believe it will work. I will push this image to my own dockerhub repo.
