title: Why Elasticsearch and Kibana generating garbage data ceaselessly?
body: <p>I just installed Elasticsearch and Kibana. X-pack has been enable. I never put any data into Elasticsearch, but when I use Kibana to monitor elasticsearch, I found the number of data increased automatically. I have to stop Elasticsearch and Kibana to make it stop. Why this phenomenon happen? And how can I fix it?</p>
  
  <p>PS: Elasticsearch and Kibana version is 7.11.1.</p>
  <p>The increasing number of data: kibana&gt;stack monitoring&gt;Elasticsearch&gt;Overview&gt;data.
  The red part was from: 2M ---&gt; 314M, I don't know what it done.
