This library provides single entry point to all profiling functionality available in golang 1.5.
StartProfiling starts writing trace and cpu profile to some random directory it creates before running.
When you call StopProfiling it writes heap profile to the same directory as well as stopping current profiling.
By default, StartProfiling writes profiles up to 5 minutes in order to avoid forgotten profiling.
http.HandleFunc("/", index)
// we start profiling tools at a separate address in background
go func() {
profilingAddress := ":8033"
fmt.Printf("Running profiling tools on %v\n", profilingAddress)
if err := goprof.ListenAndServe(profilingAddress); err != nil {
panic(err)
}
}()
By default, the library writes logs about start/stop profiling and errors using standard go logger. You can provide your own log function in order to make it fit your logging or shut up the logging at all.
We don't use much log levels since all the messages have quite the same level.
