Metricbeat extra fields

[elasticforme (Sachin)]

I have just enable metricbeat.
using very simple config.

metricbeat.config.modules:
  path: ${path.config}/modules.d/*.yml
  reload.enabled: false

setup.template.settings:
  index.number_of_shards: 1
  index.codec: best_compression

setup.dashboards.enabled: true
setup.kibana:
  host: "http://localhost:5601"

output.elasticsearch:
  hosts: ["localhost:9200"]

I have only enable system.yml in /etc/metricbeat/module.d/ directoy.

I got lot of fields in my index. like kubernetes., postgresql., docker*, It has total 3625 field listed in metricbeat* index pattern.

where are they coming from? my system do not even have any kubernetes installed or running.

found my problem. there is default metricbeat template and you have to update and remove a objects which you don't need it.
