Data is updated every second. We keep data for last day.

User https://github.com/dgryski/ proposed interesing way for turning debugcharts on/off for your project:

You can add tagged file like this in your code

// +build debugcharts

package main

If you want to use debugcharts, then build your project with -tags debugcharts

Overview

Simple live charts for memory consumption and GC pauses.

To use debugcharts, link this package into your program:

import _ "github.com/mkevac/debugcharts"

If your application is not already running an http server, you need to start one. Add "net/http" and "log" to your imports and the following code to your main function:

go func() {
	log.Println(http.ListenAndServe("localhost:6060", nil))
}()

Then go look at charts:

http://localhost:6060/debug/charts
