I started sending data to elasticsearch via filebeat and metricbeat. The corresponding indexes were created and I worked on dashboards. After two or three days, the filebeat and metricbeat index names changed from filebeat-7.9.3-2020.10.30-000001 to filebeat-7.9.3 and from metricbeat-7.9.3-2020.10.30-000001 to metricbeat-7.9.3. And the data of indexes were removed. The shards were broken and the dashboards are not working.
What can be the reason? Is there a configuration setting related to that issue?
