Setting up StrongLoop with my node applications

I'm currently testing platforms that provide a monitoring service for nodejs application. So I found (for now) StrongLoop and AppDynamics (recently acquire nodetime).

Actually I'm testing StrongLoop service. I have followed all the steps describe in the documentation but I can't see any data on the dashboard, only the StrongLoop Demo App. Here is all the steps :

• npm install -g strongloop
• npm install --save strong-agent
• $ slc strongops (command that create strongloop.json file)
• add "require('strong-agent').profile();" line on first line of each applications (2)
• restart my applications (using PM2 to manage my applications - cluster mode, AWS EC2, Ubuntu)

Any idea ?

Tank you.
