Overview of the ELK Stack for Observability
The ELK stack is a developer-facing observability and search platform used for centralized logs, event analytics, audit search, troubleshooting dashboards, and operational monitoring. It consists of three primary tools:
- Elasticsearch: Stores, indexes, searches, and aggregates JSON documents.
- Logstash: Ingests events, transforms them, and routes them to Elasticsearch or other outputs.
- Kibana: Provides a visualization layer to explore indexed data through dashboards, saved searches, and operational views.
