I am very new to ELK and I have been mainly using Kibana to do some visualization, which means that all the data has already been loaded into Kibana for me.
I have different indexes in Kibana and all of them were working fine until x of n shards started to fail in one of the indices (all the other ones are still working fine). The only thing that I can think about is that we asked for the Index Pattern to be refreshed in this specific Index that is failing.
When I use the dev tools, the status of this index is still green and I can still query anything I want. But whenever I try to use the discover, visualize, or dashboard tabs of Kibana the shards fail and I cannot see any results.
Is this because the Index Pattern was refreshed? If so, what should I do to solve the issue?
Any material or help is highly appreciated.
