title: Azure SQL Database "DTU percentage" metric
body: <p>With the new <a href="https://docs.microsoft.com/en-us/azure/sql-database/sql-database-purchase-models" rel="noreferrer">Azure SQL Database tier structure</a>, it seems important to monitor your database "DTU" usage to know whether to upgrade or downgrade to another tier.</p>
  
  <p>When reading <a href="https://docs.microsoft.com/en-us/azure/sql-database/sql-database-service-tiers-dtu" rel="noreferrer">Azure SQL Database Service Tiers and Performance Levels</a>, it only talks about monitoring with CPU, Data and Log percentage usage.</p>
  
  <p>But, when I add new metrics, I also have an <strong>DTU percentage</strong> option:</p>

  <p>I can't find any about this online.  Is this essentially a summary of the other DTU-related metrics?</p>
