pprof

pprof

pprof publishes runtime profiling data at endpoints under /debug/pprof.

You can visit /debug/pprof on your site for an index of the available endpoints. By default it will listen on localhost:6053.

This is a debugging tool. Certain requests (such as collecting execution traces) can be slow. If you use pprof on a live site, consider restricting access or enabling it only temporarily.

For more information, please see Go's pprof documentation and read Profiling Go Programs.
