grmon
Terminal monitor for Go process goroutines via pprof
TLDR
SYNOPSIS
grmon [-i *seconds*] [-host *host:port*] [-endpoint *path*]
DESCRIPTION
grmon is an interactive terminal UI for watching goroutines in a running Go program. The target process must expose Go's net/http/pprof endpoints (or start the small grmon agent). grmon polls the profile endpoint and displays goroutine counts and stacks; you can pause refresh, filter, sort, and expand individual traces.Default target is localhost:1234 with path /debug/pprof. In the target app, either call grmon.Start() from the agent package or serve pprof yourself (for example http.ListenAndServe(":6060", nil) with _ "net/http/pprof" imported).
PARAMETERS
-i *seconds*
Refresh interval (default: 5). 0 disables automatic refresh.-host *host:port*
Target host (default: localhost:1234).-endpoint *path*
pprof base path (default: /debug/pprof).Interactive keys include r refresh, p pause, s sort, f filter, arrows/j/k move, Enter expand, t full-screen trace, q quit.
INSTALL
CAVEATS
The target must expose pprof; binding pprof to a public interface is a security risk. Stack collection has runtime cost. go get install paths may differ by Go module mode—prefer current module install instructions from the repository.
