This error. If I don't use Prometheus agent then its working as expected.
*I am adding Prometheus servers configurations in the setenv.sh file of
tomcat. As below:-*
JAVA_OPTS="$JAVA_OPTS -Dfile.encoding=UTF8
-Dorg.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false
-Duser.timezone=GMT -Xmx1024m -XX:MaxPermSize=256m"
#JAVA_OPTS="$JAVA_OPTS -Dfile.encoding=UTF8
-Dorg.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false"
CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=5005
-Dcom.sun.management.jmxremote.ssl=false

-Djava.rmi.server.hostname=localhost
-javaagent:/opt/liferay/jmx_prometheus_javaagent-0.13.0.jar=5000:/opt/liferay/tomcat.yml"
*Is this Prometheus agent is compatible with java 1.6 version of it require
newversion of java to run.*
