OpenTelemetry profiles enters public alpha

I wonder how this compares to grafana pyroscope, which is really good for this sort of thing and already quite mature:

Relatedly: Has anyone profiled the performance and reliability characteristics of rsyslogd (Linux and FreeBSD distributed syslogger, maybe other platforms too) in its mode where it’s shipping logs to a central node? I’ve configured and used it with relatively small (high single digit nodes, bursts of activity to a million or two requests per minute or so) set-ups but have wondered if there’s a reason it’s not a more common solution for distributed logging and tracing (yes it doesn’t solve the UI problem for those, but it does solve collecting your logs)

Like… has anyone done a Jepsen-like stress test on rsyslogd and shared the results? I’ve half-assedly looked before and not been able to find anything.

Very excited for this. We've used the Elixir version of this at $WORK a handful of times and have found it exceptionally useful.

It suprises me that anything designed by the OTel community could ever meet 'low-overhead' expectations.
