JMX_exporter가 Prometheus & Grafana에서 오류를 표시합니다.

Question

jetty를 기반으로 배포 된 Java 응용 프로그램을 모니터링하기 위해 JMX 내보내기 도구를 사용했습니다.

나는 jmx_prometheus_javaagent-0.1.0.jar 파일

을 다운로드 배포 jmx_exporter 명령을 사용하여 자바 응용 프로그램

nohup java -javaagent:./jmx_prometheus_javaagent-0.1.0.jar=7101:config.yaml -Dorg.eclipse.jetty.server.Request.maxFormContentSize=10000000 -Xms256m -Xmx256m -Djava.io.tmpdir=epoch_temp_dir -jar jetty-runner-9.0.7.v20131107.jar --log yyyy_mm_dd-java-application-1-request.log --out yyyy_mm_dd-java-application-1-output.log --port 8091 --path /java-application-1 java-app1.war >> java-application-1.log 2>&1 & 

config.yaml

#cat config.yaml
