What does the warning “x of y shards failed” in Kibana mean?

2

It means data is not present in x number of index of Txnstore. So, Kibana will show a visualization/dashboard just for (y-x) index’s data.

Refer Kibana Reporting for more info.

Hi @mrunalini
Reason for this worning - when you have old index data in Txnstore. After that you are adding new fields, creating reports using that field and you forgot to add mappings for that new field in old indexes.

Hi,

In ElasticSearch an index can store a large amount of data that can exceed the hardware limits of a single node. Elasticsearch provides the ability to subdivide your index into multiple pieces called shards. When you create an index, you can define the number of shards that you want. Documents are stored in shards, and shards are allocated to nodes in your cluster.

There can be n number of reason why a shard failed to load. Sometimes may be due to n/w issue, hardware space issue, data aggregation issue or Field Type Conflict

You can inspect the browser requests and find the actual rca.
