title: Which is better, Nagios or Sensu?
body: <p>I am unsure about which monitoring framework to use. Currently I am looking at either <a href="http://www.nagios.org/">Nagios</a> or <a href="http://www.sonian.com/cloud-monitoring-sensu/">Sensu</a>.</p>
  
  <p>Can anybody give me a good reference which shows a comparison of these two (or any other monitoring tool which may be a good solution)? My main intention is to scale-out on EC2. I am using Opscode Chef for system integration.</p>
