Linux under Visualvmware JVM monitoring configuration

1. Installing OPENJDK

Centos:yum Install JAVA-1.8.0-OPENJDK Java-1.8.0-openjdk-devel

2.

# cd/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.31-1.b13.el6_6.x86_64/jre/lib/management/# CP Jmxremote.password.template jmxremote.password# chmod 644 jmxremote.password# VI jmxremote.passwordmonitorrole  QED      Controlrole   

3.JSTATD Start with daemon process

# jstatd-j-djava.rmi.server.hostname=172.28.37.200 &[1] 8601# Could not create remote objectaccess denied ("Java.uti L.propertypermission "" Java.rmi.server.ignoreSubClasses "" write ") java.security.AccessControlException:access Denied ("Java.util.PropertyPermission" "java.rmi.server.ignoreSubClasses" "write") at Java.security.AccessControlContext.checkPermission (accesscontrolcontext.java:472) at Java.security.AccessController.checkPermission (accesscontroller.java:884) at Java.lang.SecurityManager.checkPermission (securitymanager.java:549) at Java.lang.System.setProperty (System.java : 792) at Sun.tools.jstatd.Jstatd.main (jstatd.java:139)

Solve:

#cd/home/jdk-1.8/bin#vim jstatd.all.policy    Grant codebase "file:${java.home}/. /lib/tools.jar "{permission java.security.AllPermission;};
#jstatd-j-djava.security.policy=jstatd.all.policy-j-djava.rmi.server.hostname=172.28.37.200 &

4. Under Windows Java_home/bin, open the Jvisualvm.exe

, showing that the CPU is not supported by the JVM and needs to establish a JVM link

Under Tomcat, modify and add JVM parameters

# cd/root/apache-tomcat-8.0.17/bin# VI catalina.sh   #找到JAVA_OPTS, added below, added location not required

java_opts= "$JAVA _opts-dcom.sun.management.jmxremote         -dcom.sun.management.jmxremote.port=9999         - Dcom.sun.management.jmxremote.authenticate=false         -dcom.sun.management.jmxremote.ssl=false         - djava.rmi.server.hostname=172.28.37.200 "#/startup.sh # NETSTAT-ANTP |grep 9999    #查看端口是否监听

Dubbo Service, modifying or adding JVM parameters

# Vim Service.sh

java_opts= "$JAVA _opts-dcom.sun.management.jmxremote         -dcom.sun.management.jmxremote.port=9999         - Dcom.sun.management.jmxremote.authenticate=false         -dcom.sun.management.jmxremote.ssl=false         - Djava.rmi.server.hostname=172.28.37.200 "

View Port monitoring after reboot

# NETSTAT-ANTP |grep 9999    #查看端口是否监听
