title: How do I get the current count of a metric from Graphite
body: <p>I am trying to get the value of a metric 'activelogins' from Graphite. I increment the value by 1 every time a user logs in and decrements it when he logs out. I need to show the current number of 'activelogins' in my dashboard.
  Querying using
  <code>summarize(stats_counts.user.activelogins,"99years", "sum")</code>
  as expected just gives me the sum and not the current which I actually want.</p>
  
  <p>How do I get the current count of 'activelogins' from Graphite ?</p>
