I am trying to monitor an es cluster using metricbeat elasticsearch module for some reason I can't change the index name sent to my monitoring cluster from .monitor-es-6-mb.

here is my config
metricbeat:
  config:
    modules:
      path: /usr/share/metricbeat/modules.d/*.yml
      reload:
         enabled: false
output:
   elasticsearch:
         hosts:
         - https://mycluster:443
         index: kube-%{+yyyy.MM.dd}
         password: 
         username: 
    file:
         enabled: false
         filename: metricbeat
         number_of_files: 5
         path: /usr/share/metricbeat/data
        rotate_every_kb: 10000
path:
    config: /usr/share/metricbeat
    data: /usr/share/metricbeat/data
    home: /usr/share/metricbeat
    logs: /usr/share/metricbeat/logs
processors:
- add_cloud_metadata: null
setup:
    template:
      enabled: true
      name: kube
      pattern: kube-*
and I already have template called kube in monitoring cluster.
