How do I analyze blocking profile?

An analysis of the blocking profile in Go can help identify potential performance bottlenecks caused by goroutines that are waiting for resources. By analyzing the blocking profile, developers can improve efficiency and ensure that their applications are running smoothly.

// Using the Go built-in pprof package to analyze blocking profiles package main import ( "net/http" "net/http/pprof" "os" "runtime" "log" ) func main() { // Register pprof endpoints go func() { log.Println(http.ListenAndServe("localhost:6060", nil)) }() // Create blocking example ch := make(chan struct{}) go func() { // Simulate work time.Sleep(2 * time.Second) close(ch) }() // Blocking wait <-ch // Trigger blocking profile extraction f, err := os.Create("block.prof") if err != nil { log.Fatal(err) } defer f.Close() // Start box profiling pprof.Lookup("block")->WriteTo(f, 0) }
