zabbix 3.0 利用jmx监控 tomcat
zabbix-server端的配置注意编译安装zabbix-server的时候，带上参数 --enable-java .注意，由于你是编译zabbix-java-gateway，所以，你的zabbix服务器是必须要有java环境的。
1
./configure --enable-server --enable-agent --with-mysql --enable-ipv6 --with-net-snmp --with-libcurl --with-ssh2 --enable-java
修改java的settings.sh参数，
LISTEN_IP="0.0.0.0"
LISTEN_PORT=10052
START_POLLERS=5

DBName=zabbix

JavaGateway=127.0.0.1

都修改好以后，保存并启动java
./startup.sh
查看进程：
# netstat -tlunp

从上我们看到，zabbix_agent,zabbix_server都已经开启，java也开启了，端口是10052
========================================================================================
Tomcat端配置
1.首先配置tomcat环境，注意被控端和服务器端的JDK版本要一致
2.将catalina-jmx-remote.jar 下载，并复制到
/usr/local/tomcat/lib/ 目录下
3.修改TOmcat的catalina.sh文件
1
CATALINA_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=192.168.1.224"
注意，不要根据网上人云亦云，把ssh=false也给加上。
其中,192.168.1.224为tomcat所在PCIP地址，根据你自己的环境改边就行了，你是什么IP就填什么IP
4.修改server.xml
# locate server.xml
/usr/local/tomcat/conf/server.xml
其中加入如下选项：
<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener"rmiRegistryPortPlatform="12345" rmiServerPortPlatform="12345"/>
重启tomcat
====================================================================
回到 zabbix服务器：
在zabbix服务器端用工具测试 下载cmdline-jmxclient-0.10.3.jar工具 java -jar /usr/local/src/cmdline-jmxclient-0.10.3.jar -192.168.1.224:12345 java.lang:type=Memory NonHeapMemoryUsage11/12/2014 15:39:30 +0800 org.archive.jmx.Client NonHeapMemoryUsage: committed: 552665088init: 539426816max: 587202560used: 75002232
显示有数据，最后在zabbix添加host，填上模板就OK了。
