Logstash provides an input stream to Elasticsearch for storage and search, and Kibana accesses the data for visualizations such as dashboards. [7] Elastic also provides "Beats" packages which can be configured to provide pre-made Kibana visualizations and dashboards about various database and application technologies.
Formerly the "ELK stack", short for "Elasticsearch, Logstash, Kibana".) Elasticsearch uses Lucene and tries to make all its features available through the JSON and Java API . It supports facetting and percolating (a form of prospective search ), [ 32 ] [ 33 ] which can be useful for notifying if new documents match for registered queries.

[2] It is an open-source project developed by the OpenSearch Software Foundation (a Linux Foundation project) written primarily in Java .
In many cases, the repositories of time-series data will utilize compression algorithms to manage the data efficiently. [ 3 ] [ 4 ] Although it is possible to store time-series data in many different database types, the design of these systems with time as a key index is distinctly different from relational databases which reduce discrete ...
It targeted time series databases such as InfluxDB, OpenTSDB, and Prometheus, but evolved to support relational databases such as MySQL/MariaDB, PostgreSQL and Microsoft SQL Server. [13] In 2019, Grafana Labs secured $24 million in Series A funding. [14] In the 2020 Series B funding round it obtained $50 million. [15]
TDMA frame structure showing a data stream divided into frames and those frames divided into time slots. Time-division multiple access (TDMA) is a channel access method for shared-medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. [1]
