Why is my Go `pprof` output showing blank results despite accurate application performance?

Go Tool Pprof Output Inconsistencies

The query revolves around the inexplicable output of the 'pprof' tool in Go, which provides profiling capabilities. Despite accurate performance in the past, the tool has recently started generating inconclusive results.

Regardless of the application being profiled, even relatively complex ones with numerous function calls, the 'pprof' tool returns bland call graphs and barren results, despite the applications themselves functioning properly.

The issue has persisted even after upgrading to MacOS Yosemite and El Capitan. The package 'github.com/davecheney/profile' is employed with Go v1.5.1.

To generate the profiles, the code includes 'profile.Start' and 'profile.Stop' at the beginning of the 'main' function, followed by the building and running of the binary. However, the resulting output resembles the following:

(pprof) top
269.97kB of 269.97kB total (  100%)
      flat  flat%   sum%        cum   cum%
  269.97kB   100%   100%   269.97kB   100%  
(pprof) 
Copy after login

The provided solution resolves this discrepancy by emphasizing the absence of the binary in the 'pprof' call. The correct command structure is:

go tool pprof ./orig /path/to/profile.pprof
Copy after login

This correction ensures that 'pprof' targets the compiled binary, enabling it to provide the desired profiling information.
