TOMCAT - jmx 로 monitoring

출처 : 아파치 톰캣(apache tomcat) 을 jmx 로 monitoring 하기

catalina-jmx-remote.jar 파일 Tomcat이 설치된 디렉토리의 lib디렉토리에 복사

https://archive.apache.org/dist/tomcat/tomcat-8/v8.5.23/bin/extras/

$ cd /usr/local/apache-tomcat-8.5.23/lib
$ wget https://archive.apache.org/dist/tomcat/tomcat-8/v8.5.23/bin/extras/catalina-jmx-remote.jar

IP 확인

$ ifconfig | grep "inet addr"
          inet addr:192.168.0.24  Bcast:192.168.0.255  Mask:255.255.255.0
          inet addr:127.0.0.1  Mask:255.0.0.0

setenv.sh 파일 생성

$ cd /usr/local/apache-tomcat-8.5.23/bin
setenv.sh 파일 내용
$ vi setenv.sh

• -Dcom.sun.management.jmxremote.authenticate=false / 인증하지 않음
• -Djava.rmi.server.hostname=192.168.0.24 / 톰캣이 구동되는 서버의 IP
• -Dcom.sun.management.jmxremote.ssl=false / SSL 을 사용하지 않음

#!/bin/sh

JMX_OPTS=" -Dcom.sun.management.jmxremote \
                 -Dcom.sun.management.jmxremote.authenticate=false \
                 -Djava.rmi.server.hostname=192.168.0.24 \
                 -Dcom.sun.management.jmxremote.ssl=false "
CATALINA_OPTS=" ${JMX_OPTS} ${CATALINA_OPTS}"

conf/server.xml 수정 - Listener 추가

<Server port="8005" shutdown="SHUTDOWN">

<!-- 생략 --->

<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener"
        rmiRegistryPortPlatform="9840" rmiServerPortPlatform="9841"/>

jdk의 jconsole.exe 실행

권한파일(jmxremote.access)과 로그인 암호파일(jmxremote.password) 생성

$ cd /usr/local/apache-tomcat-8.5.23/
$ echo -e "monitorRole readonly\ncontrolRole readwrite" > conf/jmxremote.access
$ cat conf/jmxremote.access
monitorRole readonly
controlRole readwrite
$ echo -e "monitorRole tomcat\ncontrolRole tomcat" > conf/jmxremote.password
$ cat conf/jmxremote.password
monitorRole tomcat
controlRole tomcat

setenv.sh 파일 수정

$ cd /usr/local/apache-tomcat-8.5.23/bin
$ vi setenv.sh

#!/bin/sh
