title: CPU usage graphs on Azure Container Instance
body: <p>When running a simple Linux container on ACI there is a huge discrepancy between the 'graphed' CPU usage in the portal compared to running 'top' in the container itself.</p>
  
  <p>I can see my process running in 'top' and the cpu usage stays at around 5% and the load on the machine is below 0.10 but the portal reports around 60% usage.  It's a single processor container.</p>
  
  <p>Under heavier loads I have seen CPU usage of 300-400 % which feels like an issue related to the number of processors but even this does not add up and as previously stated it's a single processor container</p>
  
  <p>Any thoughts ??</p>
