title: Metrics for Top-n Load, memory, CPU usage by host in Grafana
body: <p>We are trying to display the following in Grafana using the Bosun/OpenTSDB data source:</p>
  <p>a. Hosts in descending order in terms of Top-n Load<br />
  b. Top 10 memory consuming processes<br />
  c. Top CPU usage consuming processes</p>
  <p>However, we could not find suitable metrics for it.</p>
  <p>How can this information be displayed?</p>
  <p>Secondly, if the metrics are not available in Bosun/OpenTSDB, then how should you create or define new metrics for them?</p>
