How to send Raspberry PI log to Microsoft Sentinel

I've got several times following question: is it possible to onboard Raspberry PI to Microsoft Sentinel?

Yes, it is :)

I worked on this "side project" and I wrote and article about this topic that I'd like to share again.

TL;DR

I've used Ruby and Fluentd to send event to Microsoft Sentinel.

Please be aware the article was written in 2019, so naming convention used about Sentinel is a bit outdated and Microsoft Sentinel has evolved considerably since 2019 but almost all technical concepts are still valid.
