Какие компоненты составляют стек ELK (Elasticsearch, Logstash, Kibana)?

The ELK stack consists of three main components:

1. Elasticsearch — a distributed search and analytics engine that stores and indexes data, providing fast search and aggregation.

2. Logstash — a tool for collecting, processing, and forwarding logs and other data. It accepts data from various sources, transforms it, and sends it to Elasticsearch.

3. Kibana — a web interface for visualizing and analyzing data stored in Elasticsearch. It allows building dashboards, charts, and reports based on logs and metrics.
