Used to analyze jrockit virtual machine performance, can real-time monitor performance, analyze memory usage and so on, the current version has very detailed help, but also TMD Chinese, thanks to Oracle.

Server-side configuration is simple, that is, configure JMX

1. Prepare .access and .password files for access control

Mkdir-p / etc/jre_accesscp $JAVA_HOME/jre/lib/management/jmxremote.password.template / etc/jre_access/jmxremote.passwordcp $JAVA_HOME/jre/lib/management/jmxremote.access / etc/jre_access/jmxremote.accessvi / etc/jre_access/jmxremote.password#... # monitorRole QED# controlRole R&Dusername userpasswd vi / etc/jre_access/jmxremote.access##monitorRole readonly#controlRole readwrite\ # create javax.management.monitor.* Javax.management.timer.*\ # unregisterusername readwrite chmod 600 / etc/jre_access/jmxremote.passwordchmod 644 / etc/jre_access/jmxremote.access

two。 Add startup jmx class

# Monitoring port opened by jport= # IP$JAVA_HOME/bin/java-Dcom.sun.management.jmxremote.port=$jport-Dcom.sun.management.jmxremote.ssl=false-Dcom.sun.management.jmxremote.authenticate=true-Dcom.sun.management.jmxremote.access.file=/etc/jre_access/jmxremote.access-Dcom.sun.management.jmxremote.password.file=/etc/jre_access/jmxremote.password-Djava.rmi.server.hostname=$SERVERIP of the server where the SERVERIP= service resides. # connect the JAVA project parameters

3.tomcat add JMX Monitoring

Similar to the java project, it uses Tomcat/7.0.39 installed by yum

Directly posted to the JAVA_OPTS in tomcat7.conf can start, but can not be used to turn off egg pain. If you remove the parameter, you can turn it off.

Have no choice but to change the tomcat7.conf into two copies of tomcat7_start.conf,tomcat7_stop.conf and modify / etc/init.d/tomcat7

#-# add code #-cp / etc/tomcat7/tomcat7.conf / etc/tomcat7/tomcat7_start.confcp / etc/tomcat7/tomcat7.conf / etc/tomcat7/tomcat7_stop.conf vi / etc/tomcat7/tomcat7_start.conf#. JAVA_OPTS= "$JAVA_OPTS-verbosegc-Dcom.sun.management.jmxremote.port=7091-Dcom.sun.management.jmxremote.ssl=false-Dcom.sun.management.jmxremote. Authenticate=true-Dcom.sun.management.jmxremote.access.file=/etc/jre_access/jmxremote.access-Dcom.sun.management.jmxremote.password.file=/etc/jre_access/jmxremote.password-Djava.rmi.server.hostname=218.58.x.x "vi / etc/init.d/tomcat7# modify TOMCAT_CFG part # Get the tomcat config (use this for environment specific settings) TOMCAT_CFG_start=" / etc/tomcat7/tomcat7_start.conf "if [- r" $TOMCAT_CFG_start "] Then. $TOMCAT_CFG_startfi TOMCAT_CFG_stop= "/ etc/tomcat7/tomcat7_stop.conf" if [- r "$TOMCAT_CFG_stop"]; then. $TOMCAT_CFG_stopfi # modify function parseOptions () function parseOptions_start () {options= "" options= "$options $(awk'! / ^ # / & &! / ^ $/ {ORS="; print "export", $0, ";"}'\ $TOMCAT_CFG_start) "if [- r" / etc/sysconfig/$ {NAME} "] Then options= "$options $(awk'! / ^ # / & &! / ^ $/ {ORS="; print "export", $0, " "}'/ etc/sysconfig/$ {NAME})" fi TOMCAT_SCRIPT= "$options ${TOMCAT_SCRIPT}"} function parseOptions_stop () {options= "" options= "$options $(awk'! / ^ # / & &! / ^ $/ {ORS="; print "export", $0, " "}'\ $TOMCAT_CFG_stop)" if [- r "/ etc/sysconfig/$ {NAME}"]; then options= "$options $(awk'! / ^ # / &! / ^ $/ {ORS="; print "export", $0, " "}'\ / etc/sysconfig/$ {NAME})" fi TOMCAT_SCRIPT= "$options ${TOMCAT_SCRIPT}"} # modify parseOptionsfunction start () {...

This allows the client to monitor the JVM project over an Oracle JRockit Mission Control connection
