pprof reads a collection of profiling samples in profile.proto If the profile samples contain machine addresses, pprof can symbolize them through the use of the native binutils tools (addr2line and nm).

Package pprof serves via its HTTP server runtime profiling data in the format expected by the pprof visualization tool. To use pprof, link this package into your program

Package pprof writes runtime profiling data in the format expected by the pprof visualization tool. For compatibility with various tools that read pprof data, profile names should not contain spaces.

There's a bunch of pprof documentation on the internet but I found a few things confusing so here First - when working with pprof it's good to be running a recent version of Go! For example Go 1.8...

The file runtime/pprof/pprof.go contains the detailed information and implementation of the profiles. Obtaining heap data with pprof. There are two main ways of obtaining the data for this tool.

Profiling helps us understand CPU and memory intensive code and helps us write better code for optimization. In this post, we are going to take a look at the pprof package which helps us do the...

PProf is a cpu profiler that is part of the gperftools developed by Google for analyzing multi-threaded The pprof package of golang's standard library provides the data needed by the pprof tool via HTTP.

Pprof's -inuse_space, -inuse_objects, -alloc_space, and -alloc_objects flags select which to display, defaulting The allocs profile is the same as the heap profile but changes the default pprof display to...

If you run your pprof command on a different machine, then you can also import those results into the IDE. One way to obtain these profiles is to run either the tests or benchmarks from your application.

Step #5: run go tool pprof. Pass your binary location, and the location of the cpu.pprof file as returned when running your program. You can generate the analysis in various formats.

WriteTo writes a pprof-formatted snapshot of the profile to w. If a write to w returns an error, WriteTo returns that error. Passing debug=0 prints only the hexadecimal addresses that pprof needs.

pprof --disasm=getdir /bin/ls ls.prof. Further documentation for pprof is maintained as a web page called cpu_profiler.html and is likely installed at one of the following locations

I previously looked at using pprof to see what's currently using memory in Prometheus. If you specify the -alloc_space flag then the total allocations since process start will be reported
