Elastic Agent 를 사용해 보려고 합니다.

최근에 릴리즈 된 Elastic Stack 7.9.0 으로 진행 했습니다.

 

진행 간에 순서대로 실행한 내용을 그냥 올려 둡니다.

Kibana IngestManager 확인)

Elasticsearch + Kibana + ElasticAgent + Elastic Common Schema 구성이며, 기존에 beats 를 이용해서 log/data shipper 기능을 구현 하던걸 agent 하나로 대체 할 수 있을 것 같습니다.

더불어서 ECS 기반의 Kibana 에서 Dashboard 와 Visualize 에 대해서도 Preset 을 제공 하니 잘 활용하면 아주 멋질 것으로 기대 합니다.
