What did you do?
Added basic CPU profiling code to main():
f, err := os.Create("test.prof")
if err != nil {
log.Fatal(err)
}
pprof.StartCPUProfile(f)
defer pprof.StopCPUProfile()
Then I ran my program and threw a load tester at it.
What did you expect to see?
Data in test.prof after gracefully exiting my program.
What did you see instead?
After heavily loading my program with a load testing tool I made I observed that no bytes were ever written to test.prof. It seems like there is no sampling being done at all...?
