pprof is a Go package that provides a set of HTTP handlers for profiling Go programs. It is built on top of the standard net/http/pprof package and is designed to work with the lightning web framework.
go get github.com/lightning-contrib/pprofHere is an example of how to use this package:
package main
import (
"github.com/go-labx/lightning"
"github.com/lightning-contrib/pprof"
)
func main() {
app := lightning.DefaultApp()
pprof.Register(app)
app.Run()
}By default, the package's HTTP handlers are registered under the /debug/pprof prefix. You can customize the prefix by passing an optional argument to the Register function
pprof.Register(app, "/admin/debug/pprof")Once the package's HTTP handlers are registered, you can access them using a web browser or a command-line tool like go tool pprof. Here are some examples:
- To view the heap profile of your Go program, visit http://127.0.0.1:6789/debug/pprof/heap?debug=1 in your web browser.
- To view the goroutine profile of your Go program, visit http://127.0.0.1:6789/debug/pprof/goroutine?debug=1 in your web browser.
- To view the block profile of your Go program, visit http://127.0.0.1:6789/debug/pprof/block?debug=1 in your web browser.
- To view the mutex profile of your Go program, visit http://127.0.0.1:6789/debug/pprof/mutex?debug=1 in your web browser.
- To view the symbol table of your Go program, visit http://localhost:6789/debug/pprof/symbol?debug=1 in your web browser.
Note that the above URLs assume that your lightning application is running on localhost and listening on port 6789. If your application is running on a different host or port, you need to adjust the URLs accordingly.
