monitoring a node.js server [closed]

I am looking for a way to get some sort of monitoring, statistic or management data out of a node.js server instance - not sure what to search for or where to start. Any advice appreciated.

Stats would be requests processed (if applicable) - number of connections and so on.

How do I know if NodeJS server is running?

To check the node server running by logging in to the system In windows you can simply go to the Task Manager and check for node in the application list. If it is there then it is running in the machine.

Don't know if it will fit your needs, but you can try to look at node-monitor. Also Joyent is doing some advanced real-time performance analysis stuff, but it's probably only for their cloud services.
