title: Cassandra nodetool cfstats - Read Count is always 0
body: <p>I've got a problem with monitoring my Cassandra node. I ran</p>
  
  <pre><code>nodetool cfstats keyspaceName.tableName
  </code></pre>
  
  <p>Unfortunately Read Count is always 0 and Read Latency is NaN. I am doing reads and writes but only writes metrics are updated.</p>
  
  <p>Here is what I got as an output:</p>
