Go程序運行時分析數據：gometry

一個可視化界面對來自Go程序運行時數據進行分析。

Installation

go get github.com/rakyll/gometry/cmd/gometry

The program you're willing to profile should import the github.com/rakyll/gometry/http package. The http package will register several handlers to provide information about your program during runtime.

import _ "github.com/rakyll/gometry/http"

// If your application is not already running an http server, you need to start one. 
go func() {
    log.Println(http.ListenAndServe("localhost:6060", nil))
}()

Now, you are ready to launch the gometry.

$ gometry

Point your browser to http://localhost:6464.

Goals

• Building a lightweight tool that works well with live profiles is a necessity. Over the time, I recognized that a lot of people around me delayed to use the existing pprof tools because it's a tedious experience.
• gometry has no ambition to provide the features at the granularity of the features of the command line tools. Users should feel free to fallback to go tool pprof if they need more sophisticated features. gometry should also provide interfaces to let the users to export their profile data and continue to work with the go tool.
• Allow users to filter, hide and ignore by symbol names. Make it easier to generate graphs, make it easier to browse extremely large image files.
• Allow users to work with their custom user profiles.
• Increase the awareness around profiling tools/packages in Go.
• Provide additional lightweight stats where possible.
