title: Understanding Kusto
body: <p>I am trying to understand Kusto (Log Analytics Query Language in Azure).</p>
  
  <p>According to the documentation;</p>
  
  <p>To retrieve , <code>project name</code> and <code>resultsCode</code> from the <code>dependencies</code> table, I need to enter the following:</p>
  
  <pre><code>dependencies 
  | project name, resultCode
  </code></pre>
  
  <p>The machines I have subscribed to do not have this table. </p>
  
  <p>I am using the <code>heartbeat</code> table and trying to retrieve computer and category like so:</p>
  
  <pre><code>Heartbeat 
  | Category, Computer , IsGatewayInstalled
  </code></pre>
  
  <p>I however get the following error:</p>
  
  <p>Query could not be parsed at 'Category' on line [2,2]</p>
  
  <blockquote>
    <p>Token: Category Line: 2 Position: 2</p>
  </blockquote>
  
  <p>This seems trivial and will appreciate any pointers on this.</p>
