title: What's the best way to monitor your REST API?
body: <p>I've created an API based on the RESTful pattern and I was wondering what's the best way to monitor it? Can I somehow gather statistics on each request and how deep could I monitor the requests? </p>
  
  <p>Also, could it be done by using open source software (maybe building my own monitoring service) or do I need to buy third party software? </p>
  
  <p>If it could be achieved by using open source software where do I start?</p>
