How do I use pprof for memory profiling?

Using pprof for memory profiling in Go is an essential technique for understanding memory usage and identifying potential memory leaks in your applications. By following these steps, you can generate heap profiles to analyze your program's memory allocations.

Example of Memory Profiling with pprof


            package main

            import (
                "net/http"
                "net/http/pprof"
                "log"
                "runtime"
                "runtime/pprof"
                "os"
            )

            func main() {
                // Start pprof for HTTP profiling
                go func() {
                    log.Println(http.ListenAndServe("localhost:6060", nil))
                }()

                // Create memory profile file
                f, err := os.Create("memprofile.prof")
                if err != nil {
                    log.Fatal(err)
                }
                defer f.Close()

                // Run some code that consumes memory
                performMemoryIntensiveOperation()

                // Take a memory profile
                runtime.GC() // run garbage collection
                if err := pprof.WriteHeapProfile(f); err != nil {
                    log.Fatal(err)
                }
            }

            func performMemoryIntensiveOperation() {
                // Simulate memory allocation
                data := make([]byte, 10e6) // Allocate 10MB
                _ = data
            }
