Yesterday I upgraded my elasticsearch and kibana from 7.12.0 to 7.12.1. I upgraded metricbeat and filebeat too that I used to monitoring and parse logs from elasticsearch.
Today when I enter on monitoring page it shows an empty page. I could see that endpoint
http://myhost:5601/api/monitoring/v1/clusters response empty.
I checked indices was created and it has data. But I see a sensible mapping changes that could explain the error:
Today index has cluster_uuid as text and keyword but yesterday only as keyword.
When I search monitoring with ranges of yesterday works well, but after new index was created monitoring shows empty.
I don't have idea how can fix that and if it was a known bug and it was fixed in news releases.
Any help could be appreciated. If you need any more info please tell me.
Thanks in advance,
