Configuring VisualVM with tomcat + linux
VisualVM is a tool that provides a visual interface for viewing detailed information about Java applications while they are running on a Java Virtual Machine (JVM), and for troubleshooting and profiling these applications.Firs of all you need to configure JMX. For tomcat you need to perform this:
- In folder %CATALINA_HOME%/conf need to create remote.users with content: USER_1 PASSWORD_2
USER_2 PASSWORD_2 - In folder %CATALINA_HOME%/conf need to create remote.acl with content: USER_1 PERMISSION_1
USER_2 PERMISSION_2
where permissions: readonly, readwrite - chmod 400 remote.users
- chmod 400 remote.acl
- chown tomcat:tomcat remote.users
- chown tomcat:tomcat remote.acl
- In tomcat %CATALINA_HOME%/bin/catalina.sh need to add: CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote.password.file=/opt/tomcat/conf/remote.users
-Dcom.sun.management.jmxremote.access.file=/opt/tomcat/conf/remote.acl -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=7777
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=1.1.1.1"
where hostname - is tomcat server ip, and port - any not used port - Restart Tomcat
- Visual VM comes with JDK from 6u7, run it on your local machine $JAVA_HOME/bin/jvisualvm
- Click File->Add JMX connection use user, password, host and port
- Will appear new perspective whith your server connection
