title: How to expose data to zabbix
body: <p>Here is my goal:  I would like to be able to report various metrics to <a href="http://www.zabbix.com/" rel="nofollow">zabbix</a> so that we can display the graphs on a web page.  </p>
  
  <p>These metrics include:</p>
  
  <ul>
  <li>latency per soap service submission</li>
  <li>various query results from one or more databases.</li>
  </ul>
  
  <p>What things do I need to write and/or expose?  Or is the zabbix server going to go and get it from an exposed service somewhere?</p>
  
  <p>I've been advised that a script that returns a single value will work, but I'm wondering if that's the right way.</p>
