grmon
Command line monitoring for goroutines
<p align="center"><img src="https://bradley.codes/static/img/grmon.gif" alt="grmon"/></p>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"
...
grmon.Start()
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:
grmon
By default, grmon will automatically refresh every 5s. Pause automatic refresh(p) to enable the cursor and expand the full trace for a selected goroutine(<enter>).
