title: How to get InfluxDB measurement size?
body: <p>I have a an InfluxDB measurement named <code>kpi</code>. I want to get the size of that single measurement in MB.</p>
  
  <p>So far I have tried:</p>
  
  <pre><code>du -sh /var/lib/influxdb/data/demo/
  27M     /var/lib/influxdb/data/demo/
  </code></pre>
  
  <p>But this command gives me the size of the whole database.</p>
  
  <p>I have also tried this command:</p>
  
  <pre><code>&gt; select count(counter) from kpi
  
  name: kpi
  time count
  ---- -----
  0    1479533
  &gt;
  </code></pre>
  
  <p>But this only gives me the entries count.</p>
  
  <p>How can I get the size of this particular measurement?</p>
