Here's a brief overview of each component and how they work together:
Logstash:
Logstash is a data collection and processing pipeline tool. It's used to ingest, transform, and enrich data from various sources. These sources can include log files, databases, APIs, and more. Logstash allows you to apply filters and transformations to the incoming data before sending it to Elasticsearch for indexing. For example, you can use Logstash to parse and structure unstructured log data, convert data formats, and even enrich the data by adding additional fields.
Elasticsearch:
Elasticsearch is a powerful and distributed search and analytics engine. It's designed for real-time search and analysis of large volumes of data. Elasticsearch is used to index and store the data ingested by Logstash, making it highly searchable and performant. It employs a distributed architecture that allows data to be split across multiple nodes, providing scalability, fault tolerance, and fast search capabilities. Elasticsearch also provides a RESTful API for querying and interacting with the indexed data.
Kibana:
Kibana is a data visualization and exploration tool that works in conjunction with Elasticsearch. It provides a user-friendly interface for creating dashboards, visualizations, and reports based on the data stored in Elasticsearch. With Kibana, you can easily create charts, graphs, maps, and tables to help you analyze and understand your data. Kibana dashboards can display real-time information and help users gain insights from the data stored in Elasticsearch.
