Instrumenting node.js

So you have jumped on the node.js band wagon and things are going well. So well in fact that you now love node, its awesome, you tell everyone how good it is.

How being able to only write one language on the front end and the backend (well, kind of) makes you so much faster and more productive.

And then you do a new release and things slow down. You don’t know where, you don’t know what ‘slow’ means or even what your past performance was. You just have an email from some manager or some customer who says “things feel slower”. What do you do now? Where do you start looking?
