pprof

RU: pprof

pprof is Google's profiling data format (a gzip-compressed protocol buffer) and the accompanying CLI tool for collecting, visualising, and querying profiles of CPU time, memory allocations, goroutine stacks, and more. Go's standard library exposes profiles via runtime/pprof and net/http/pprof; the standalone tool renders flame graphs, call-graph dot files, and top-N tables from any conforming profile.
