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.

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.

Nodetime can monitor different metrics, such as HTTP Response time, CPU time, OS Load, etc. It is also possible to set up email Alerts based on these metrics. More in the blog post Monitoring Node.js Application Performance.
