ELK
Definition
ELK refers to a stack of three open-source projects: Elasticsearch, Logstash, and Kibana. Elasticsearch is a search and analytics engine, Logstash is a server-side data processing pipeline that ingests data from multiple sources simultaneously, and Kibana is a visualization layer that works on top of Elasticsearch. Together, they are used for logging, monitoring, and data analysis, providing powerful insights into system and application performance.
