The purpose of this platform is to facilitate log query During O M and R D. Kibana is a free web shell. Logstash integrates various log collection plug-ins and is also an excellent regular-cut log tool. Elasticsearch is an open-source search engine framework (supporting cluster architecture ).

ElasticSearch-Basic Concepts
For articles translated by others, it is very important to master the following basic concepts for learning Elasticsearch. You can try to align the following concepts with MySQL (databases, tables, data rows, fields.
Basic Concepts
Elasticsearch has several core concepts. Understanding these concepts from the very beginning will be of
Full-text search engine Elasticsearch getting started tutorial,
Full-text search is the most common requirement. Open-source Elasticsearch (hereinafter referred to as Elastic) is the first choice for full-text search engines.
It can quickly store, search, and analyze massive data volumes. Wikipedia, Stack Overflow, and Github all use it.
The underlying layer of Elastic is the Open Source library Lucene.
