grmon

Command line monitoring for goroutines

grmon

Install

go get -u github.com/bcicen/grmon

Usage

Simply import and call grmon.Start() somewhere in your code:

import "github.com/bcicen/grmon/agent"

alternatively, you may just start the pprof server directly:

import (
	"net/http"
	_ "net/http/pprof"
)
...
go http.ListenAndServe(":1234", nil)

now grmon can connect to the running program:
