Fixes #12

The implementation of websocket module for fastthtp is different. So, changing sendStats to public. And added an example of a web framework fiber that uses fasthttp.

Thanks for this tool, it's really useful for debug.

Could it be possible to add custom metrics and not only those expose by runtime?

I'm developping an application and it exposes a lot of internal metrics.

Thank.

Is it somehow possible to use this package with fasthttp as HTTP wrapper in combination with fasthttp-routing?

Because I really like the project and really want to integrate it into one of my projects which bases on these packages.

Hi,

I tested with Firefox (103.0.2 Arch Linux (64 bits)) and Chromium (104.0.5112.79 Arch Linux (64 bits)). It works perfectly with Chromium but in Firefox, the graphs are not "responsive" and end up in-line.

Left - Firefox Right - Chromium

This fixes the example removed in #31

For static files to be accessible, we need to register a catch-all route in go-chi: /debug/statsviz/*

The statsviz GUI is now accessible via http://localhost:8080/debug/statsviz/

hey - love the project. so, my own server has quite an extensive list of handlers, and I just want to put this under a deeper directory structure. actually, I just needed the NewIndex function, but i added the RootDir stuff in case it was useful.

the main process may be killed and then restarted while developing. but therefore the webpage stopped receiving metrics from the process? so can you please make the webpage reconnect the backend automatically after the restart?

func SendFrequency(freq time.Duration) OptionFunc {
	return func(s *server) error {
		s.freq = freq
		return nil
	}
}

func sendStats(conn *websocket.Conn) error {
	tick := time.NewTicker(defaultSendFrequency)
	defer tick.Stop()

	var stats stats
	for {
		select {
		case <-tick.C:
			runtime.ReadMemStats(&stats.Mem)
			stats.NumGoroutine = runtime.NumGoroutine()
			if err := conn.WriteJSON(stats); err != nil {
				return err
			}
		}
	}
}

sendStats always use defaultSendFrequency, instead of server.freq. so that SendFrequency does nothing.

I noticed that server.freq is unused despite the fact there's a special option to set custom frequency. So, I added a function NewWsHandler that accepts send frequency and returns http.HandlerFunc. Old behavior of Ws is preserved.

Improve testing Reorganize example (one example per directory) Improve the ci step which build all examples Various improvements to README.md and CONTRIBUTING.md RegisterDefault now returns an error instead of calling log.Fatal

pretty standard stuff, maybe reuse a template or use a template generator?

Issue template should thank the user and ask them:

• to run go env
• to share Go code
• to explain what they did
• what they were expecting
• what happened instead

PR template should just thank the user and ask them to link the PR to a specific issue (and possibly to have created that issue first)

	web.Any(defaultStatsvizPrefix+":path([\\w]+)", func(ctx *context.Context) {

	})

	web.Any(defaultStatsvizPrefix+"ws", func(ctx *context.Context) {
		statsviz.Ws.ServeHTTP(ctx.ResponseWriter, ctx.Request)
	})
}

错误提示：

Custom metrics is now easier after new released #75. But it seems that custom metrics like cpu, memory, io and network etc. must be implemented only inside statsviz's plot package which would be too invasive for the lib itself. Maybe we can change statsviz's interface for add-on metrics using http package's middleware pattern?
