2026-05-230c promote aggregate-only sampling defaults in raw output modesPaul Buetow
Default aggregate-only sampling (rate 0) for futex* and clock_gettime causes BPF to suppress ring-buffer events. In -plain, -flamegraph, and headless -parquet modes there is no aggregate sink, so these probes would emit no rows even when explicitly selected. Promote those defaults to rate 1 during flag resolution; user-explicit overrides are preserved. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
