[Metricbeat] - Elasticsearch Module - `index_recovery.active_only: false` seems to be default now

[BBQigniter]

After upgrading to v8 I wondered why our .monitoring-es-8-mb index suddenly used twice as much space. I had a look into the index via Kibana-Discover and spotted that there were tons of entries with metricset.name : index_recovery. Every few seconds for ALL indices Metricbeat ingested an entry with field elasticsearch.index.recovery.stage : DONE.

After reading the documentation https://www.elastic.co/guide/en/beats/metricbeat/current/metricbeat-metricset-elasticsearch-index_recovery.html I set index_recovery.active_only: true and now it seems the scraped events are back to normal. So this sentence in the documentation is wrong:

By default only data about indices which are under active recovery are fetched. To gather data about all indices set index_recovery.active_only: false

Please, either fix this in the documentation or in Metricbeat :)

Edit: fixed typo
