JMeter - ElasticSearch 백엔드 리스너 플러그인이 작동하지 않습니다.

Question

저는 JMeter 3.3을 가지고 있으며, ElasticSearch backend listener 플러그인을 추가했습니다.

나는 JMeter를 GUI를 열어 최종 리스너를 다시 만드는 시도하고 오류로 인해 실패 :

보낸 질문을 plugin group에 있지만 응답을받지 못했습니다.

추가 플러그인/jars로만 작동합니까? 다른 버전에?

또한 https://jmeter-plugins.org/에 페이지가없는 이유는 무엇입니까 (사이트의 검색 결과에 표시되었지만).

Answer 1

좋아 되세요. 기본적으로 종속성에 대한 JSON 파일 중 하나에서 키/값 쌍이 누락되었습니다.

당기기 요청을했습니다. 현재이 문제를 해결하려면 JAR 파일을 다운로드하여 "$ JMETER_HOME/lib"폴더에 저장해야합니다.

Okio 1.13.0

OkHttp 3.9.1

GSON 2.8.2

Answer 2

누락 된 종속성 또는 잘못된 버전이있는 것 같습니다.

누락 된 종속성은 okhttp 또는 종속성 중 하나입니다.

jmeter/lib 폴더에 추가하십시오.

Answer 3

저는 플러그인을 재생성하여 jmeter-plugins에 올려 놓은 사람입니다. OkHttpClient의 두 버전간에 충돌이있는 것 같습니다. 하나는 플러그인에 의해로드되고 다른 하나는 아직 발견되지 않았습니다. 현재 조사 중이며 해결되는 즉시 2.0을 릴리스 할 예정입니다.

답장을 보내 주신 것에 대해 사과 드리고 싶습니다. 도움이 더 필요하면 제발, 제발 GitHub 저장소 페이지에서 문제를 열어 주시기 바랍니다 :).

는 플러그인 관리자를 통해 플러그인을 설치할 때 문제를 일으키는 것을 실현, 좋은,
