Logging/buffering mechanism comparison? (ring buffer, relay, etc.) (no replies)

Just wondering if anyone had some pointers on a comparison between the
various logging/buffering mechanisms out there (ring buffer, relay,
lttng buffering, etc.)? Googling was inconclusive.

Anything that has benchmarks/pros/cons would be great.

Thanks,
