title: Grafana graphs jumping - local influxdb data source
body: <p>I have grafana-server installed along with influxdb and small ruby app on one vps. 3G ram, 2vcpus, 50G ssd, 512M swap.</p>
  
  <ul>
  <li>Ruby is writing data to influxdb.</li>
  <li>Grafana is reading data from influxdb.</li>
  </ul>
  
  <p>Everytime grafana refreshes dashboard with some data, this happens:
  <a href="http://i.stack.imgur.com/ksv3B.png" rel="nofollow">click</a></p>
  
  <hr>
  
  <p>That is about 200 writes per second. Dashboard for 30 minutes, refreshing every 1 minute (one user on grafana only). Query:</p>
  
  <pre><code>SELECT count("message") FROM "chat_message" WHERE $timeFilter GROUP BY time(1s) fill(0)
  </code></pre>
  
  <p>Can I do something about that?</p>
