Joseph Lee님의 생생한 수강평, ELK 스택 (ElasticSearch, Logstash, Kibana) 으로 데이터 분석

Great! Great lecture to explain ELK stack simple and clearly. It will be much helpful for my understanding about ELK stack and BigData analysis. Look forward to get further lecture about ELK stack, such as analysis using real-time log data.
