[ELK] Unable to connect to Elasticsearch. Error: Request Timeout after 30000ms

Kibana를 실행할때 Unable to connect to Elasticsearch. Error: Request Timeout after 30000ms 에러가 나면서 실행이 안되는 경우가 있을 것이다.

(In case of using Kibana, there may be an error "Cannot connect to Elasticsearch. Error: Request Timeout after 30000ms" and it may not be executed.)

 

해결방법 (solution)

설치경로/kibana/config 하위에 kibana.yml 파일의 elasticsearch.requestTimeout 의값을 180000으로 늘려준다.

(Under Installation path/kibana/config, increase the value of elasticsearch.requestTimeout in kibana.yml file to 180000.)
