README

        
You don’t want to clutter up your computer with Docker, Prometheus, Grafana or even K8S just to monitor a Go app's heap size, right?

Use `live-pprof` to Monitor a Go app's performance. It launches in seconds, boosting your local development.

## Install

```bash

go install github.com/moderato-app/live-pprof@v1

```

## Usage

#### Step 1: setup pprof endpoints

```bash

package main

import (

	"log"

	"net/http"

	_ "net/http/pprof"

)

func main() {

	log.Println(http.ListenAndServe("localhost:6060", nil))

}

```

#### Step 2: monitor the pprof endpoints

```bash

live-pprof 6060 

# Or:

live-pprof http://localhost:6060/debug/pprof

# Both commands will monitor http://localhost:6060/debug/pprof

```

## Limitations

* Metrics data is stored in the browser memory and is cleared on page refresh.

* The page slows down as data grows due to charts rendering.

As you can see, live-pprof is mainly for local development. These limitations mean it’s not a replacement for Prometheus and Grafana.
