Elasticsearch is a search engine based on Lucene. It provides a distributed, multitenant-capable, full-text search engine with an HTTP web interface and schema-free JSON documents. Elasticsearch is developed in Java and is released as open source under the terms of the Apache Source License. Elasticsearch is the most popular enterprise search engine followed by Apache Solr, also based on Lucene.
All metrics produced by Tribestream like CPU, Memory, and Client Interactions with the TAG, such as Requests, Authentications, Database Queries, and other events are pushed asynchronously to an Elasticsearch instance.
