Hiii All,
I've just started adding Metricbeat to my K8S cluster following this tutorial: https://www.elastic.co/guide/en/beats/metricbeat/current/running-on-kubernetes.html
Everything works fine and I was able to see Metricbeat docs being received at another ELK stack instance. The confusion I had was the documents seem to be too many --- after the first night, there has been already over 2 million metric docs which takes nearly 1Gb storage... i wondered whether that's an expected behavior but I couldn't find any posts / official documentation -mentioning how frequent the Metricbeat sends metrics....
