We have been using this for a while in random real-time applications.

Its a circular logger using memory mapped files, using xxHash for each entry as a signature. Larger logged entries are chained.

It's using memory mapped files for writing (logger) and reading (ui), it has a UI and it's rough. It wasn't meant to be published,

-but since it served us nicely for some time, we reckon some help would be nice. It is licensed under BOOST.

Put the logging directory in tmpfs or similair.

There's a text based UI (FTXUI) included that scans the folder and real-time-ish log the data.

The UI will consume the CPU.

Sorry for my bad english, I only speak one language.

Happy Hacking! Stefan
