How do I make sure my script is running on Open Shift?

So, I have a restful webservice made on Node.js to lookup on a Postgresql DB. I've uploaded it on OpenShift. I'm trying to access it via Android but it doesn't work. Is there anyway I can make sure my script is running? I've already included it on the package.json. Also, is there anyway to actually see the script running to keep track of eventual errors?
