What is the OpenTelemetry eBPF profiler?

Kernel tracer for continuous profiling. Captures stacks sans agents. Symbolizes for Go via .gopclntab. Feeds Pyroscope.

How does symbolization work in Go eBPF profilers?

Raw PC → binary map → parse .gopclntab → binary search func range → name+offset. On-target, fast.

Embedded pclntab survives stripping. Others need external DWARF/servers. Go: instant, low-overhead.
