title: ganglia and host sFlow custom metrics
body: <p>25.6 and Ganglia 3.6.</p>
  
  <p>I want to extract some metrics from a program and send them with host sFlow. I've enabled the json ports in the hsflow configuration file but I don't know how to send the metrics to the host sFLow and also how to collect them with Ganglia</p>
  
  <p>What is the best way for doing this?. Maybe there are other solutions instead of using the json ports but I don't know which is the best one</p>
  
  <p>The host sflow is running in Ubuntu 12.04 LTS </p>
  
  <p>Thank you in advance</p>
