Where can I find all indices in Kibana?

If you set your Kibana dashboard configuration to _all in index settings (the default for the sample dashboard at #/dashboard/file/guided. json), all indices will be queried. From there, you can add a terms panel for the _index field. That will list the top indices in terms of number of documents that they contain.

Why is Elasticsearch health yellow?

Your Elasticsearch cluster can enter yellow health status for the following reasons: Creation of a new index. Not enough nodes to allocate to the shards or disk skew. High JVM memory pressure.

Why is Elasticsearch so fast?

The essence of Shard: the set of inverted indices

Shards are the containers of inverted indices, and we call the process from input text to inverted index as indexing. After indexing, elasticsearch will create several inverted indices tables which is the reason of searching so fast in elasticsearch.

Can Elasticsearch be used as database?

Relations and Constraints. Elasticsearch is a document oriented database. The entire object graph you want to search needs to be indexed, so before indexing your documents, they must be denormalized.

How many indexes can Elasticsearch handle?

Each Elasticsearch shard is a Lucene index. The maximum number of documents you can have in a Lucene index is 2,147,483,519.

How big should my Elasticsearch index be?

Aim to keep the average shard size between at least a few GB and a few tens of GB. For use-cases with time-based data, it is common to see shards between 20GB and 40GB in size.

How do I reduce Elasticsearch index size?

How to reduce Index size on disk?

  1. Delete unnecessary fields (or do not index unwanted fields, I am handling it at the LS level)
  2. Delete @message field (if Message field is not in use you can delete this)
  3. Disable _all field ( Be careful with this setting )

How often should I index Elasticsearch?

A refresh makes all operations performed on an index since the last refresh available for search. By default, Elasticsearch periodically refreshes indices every second, but only on indices that have received one search request or more in the last 30 seconds. You can change this default interval using the index.
