Usage

Before starting roumon, the go app which shall be monitored needs to be prepared to export pprof infos via http.

pprof

The program which shall be monitored needs to run a pprof server.

Import pprof into you program:

import _ "net/http/pprof"

Run a webserver which will listen on a specific port:

go func() {
    log.Println(http.ListenAndServe("localhost:6060", nil))
}()

Start your program and check that the pprof site is available in you web-browser: http://localhost:6060/debug/pprof

roumon

Start roumon in from your command line interface. Use optional arguments if needed.

For example roumon -debug=logfile -host=192.168.10.1 -port=8081 will start the routine monitor for the pprof profiles exposed to 192.168.10.1:8081 and write a debug logfile to ./logfile.

Run roumon with -h or --help to see all commandline argument options:

Usage of roumon:
  -debug string
        Path to debug file 
  -host string
        The pprof server IP or hostname (default "localhost")
  -port int
        The pprof server port (default 6060)

From within the Terminal User Interface (TUI) hit F1 for help F10 or ctrl-c to stop the application.
