How to access the pprof profiler on a production server?

To access the pprof profiler on a production server, you typically need to:

1. Enable the HTTP pprof server in your Go application by importing the net/http/pprof package and registering handlers, for example:

import (
    _ "net/http/pprof"
    "net/http"
)

func main() {
    go http.ListenAndServe(":6060", nil) // runs pprof on port 6060
    // other code
}

2. On the production server, restrict access to the port (e.g., 6060) only to trusted IPs or via SSH tunnel to prevent public exposure of the profiler.

3. Connect to the profiler via a browser or using the command:

curl http://localhost:6060/debug/pprof/

or analyze with go tool pprof:

go tool pprof http://localhost:6060/debug/pprof/profile?seconds=30

It is important to ensure secure access to pprof on production to avoid exposing internal information.
