This is the first proper release of xcapture eBPF thread sampler and xtop frontend TUI tool.

xCapture gives you an efficient, always-on observability signal for dimensional performance analysis of thread-level activity. In passive sampling mode on a 104 vCPU machine (~2000 threads), xcapture used 0.07% of a single CPU out of all CPU capacity.

We just had a "launch party" at P99CONF and the 20 minute talk is available at:
