Fluent-bit is an awesome tool for log streaming, it uses dynamically linked libraries (pthread and libc). In some environments - like shared hosting services - the correct libc version, or other dependencies are missing. There are also no build tools available to compile it in place. This way fluent-bit is unusable in such scenario currently.

There should be a way to compile a self-contained binary. That way compatibility can be guaranteed.

As an alternative I could write my own application with statically linked fluent-bit lib, but it's pointless as a great tool is already available.
I couldn't really find other alternatives.

IRL I run a bunch of websites on a hosting service. The # of visitors and the load most of the cases don't even justify a VM. But since there's a lack of monitoring tools it makes sense extracting the log files to some external host to process them. However, it's desired to have on-line log monitoring (eg. some malicious content causing increased number of failures).

I created a patch for myself, I'd like to share with you as an initial implementation.
