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 DebugChartServer, 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
