title: making sense of event value in GA
body: <p>I am inheriting a web app which is connected to Google Analytics. The app sends a custom event in the following fashion:</p>
  
  <pre><code> ("Operations","Main Operation", null, timeTaken)
  </code></pre>
  
  <p>where timeTaken is a variable that is taken to finish processing a bunch of data that gets displayed to the user then, based on setInterval of javascript. Now in the GA dashboard I see the following (after I click on Operations):
  <a href="https://i.stack.imgur.com/B17Xk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/B17Xk.png" alt="enter image description here"></a></p>
  
  <p>My question is what is this data telling me exactly?</p>
