[SOLVED] Ruby script process monitoring on windows

Ruby script process monitoring on windows

I want to monitor my ruby script process remotely on windows. I do know how to do it on unix based system, with god or similar monitoring framework, but the issue is that I want to have it for windows.

Basically, I want to do a couple of things:

Monitor whether the script is running
If the script stops, it should be restarted
Send the status of the script to remote server (This is not so important, I can write this option myself)

Maybe someone can suggest it.

Please note that I would prefer to have the monitoring solution written in ruby, so I could expand it further.

Solution

I found this on the forum www.ruby-forum.com and adapted it a bit you that you can see if the process (script) still runs. Restarting and reporting you can handle yourself i presume ?

require 'WIN32OLE'

procs = WIN32OLE.connect("winmgmts:\\\\.")
procs.InstancesOf("win32_process").each do |p|
  puts p.commandline if p.name == 'ruby.exe'
end

Here the available attributes
