Why is My Go pprof Output Broken, Even Though My Application Works?

Troubleshoot Go's pprof Tool Yielding Broken Output

When using the "pprof" tool for profiling Go applications, users may encounter situations where the output is consistently broken, regardless of the profiling target. This issue can manifest as sparse call graphs, barren list or top commands, despite the applications functioning properly.

The cause of this problem typically lies in the command syntax for invoking "pprof." Specifically, the command requires the path to the binary being profiled as the second argument, which may be missing in certain scenarios.

To resolve the issue, ensure that the binary path is included in the command. The correct syntax should look something like this:

go tool pprof ./orig /path/to/profile.pprof

Here, "./orig" represents the path to the binary being profiled, and "/path/to/profile.pprof" is the path to the profile file generated during profiling. By providing the correct binary path, the "pprof" tool can accurately associate the profiling data with the relevant code, resulting in informative and meaningful output.
