zabbix-2.4.2监控-使用JMX功能监控tomcat安装配置环境：Centos7.0 zabbix2.4.2
1.在zabbix-2.4.2服务端配置java环境，下载jdk，配置jdk环境变量。
tar zxvf jdk-8u25-linux-x64.tar.gz
vim /etc/profile
JAVA_HOME=/opt/jdk1.8.0_25
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME
export PATH
export CLASSPATH
2.重新编译安装zabbix添加对java监控的支持。
cd zabbix-2.4.2
./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --with-mysql --enable-ipv6 --with-net-snmp --with-libcurl --with-ssh --enable-java
make && make install
zabbix环境的配置这里不再介绍，只对增减java监控作说明。
修改/usr/local/zabbix/sbin/zabbix_java/settings.sh文件。
# This is a configuration file for Zabbix Java Gateway.
# It is sourced by startup.sh and shutdown.sh scripts.
### Option: zabbix.listenIP
# IP address to listen on.
#
# Mandatory: no
# Default:
LISTEN_IP="0.0.0.0"
### Option: zabbix.listenPort
# Port to listen on.
#
# Mandatory: no
# Range: 1024-32767
# Default:
LISTEN_PORT=10052
### Option: zabbix.pidFile
# Name of PID file.
# If omitted, Zabbix Java Gateway is started as a console application.
#
# Mandatory: no
# Default:
# PID_FILE=
PID_FILE="/tmp/zabbix_java.pid"
### Option: zabbix.startPollers
# Number of worker threads to start.
#
# Mandatory: no
# Range: 1-1000
# Default:
START_POLLERS=5
修改zabbix_server配置文件/usr/local/zabbix/etc/zabbix_server.conf
添加以下几行：
JavaGateway=127.0.0.1
JavaGatewayPort=10052
StartJavaPollers=5
启动javagateway
/usr/local/zabbix/sbin/zabbix_java/startup.sh
[root@osa zabbix_java]# netstat -napl |grep 10052
tcp6 0 0 :::10052 :::* LISTEN 18805/java
添加开机启动
echo "/usr/local/zabbix/sbin/zabbix_java/startup.sh">>/etc/rc.local
3.tomcat配置，下载catalina-jmx-remote.jar文件放到tomcat/lib下面
http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.0.15/bin/extras/catalina-jmx-remote.jar
在tomcat/conf/server.xml文件中添加：
<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener" rmiRegistryPortPlatform="12345" rmiServerPortPlatform="12346" />
在tomcat/bin/catalina.sh文件中添加
CATALINA_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.ssh=false -Djava.rmi.server.hostname=192.168.0.86"
其中hostname是被监控端的ip。
启动tomcat，下载cmdline-jmxclient-0.10.3.jar文件测试。
java -jar cmdline-jmxclient-0.10.3.jar - 192.168.0.86：12345 java.lang:type=Memory NonHeapMemoryUsage
[root@osa lib]# java -jar ./cmdline-jmxclient-0.10.3.jar - 192.168.0.86:12345 java.lang:type=Memory NonHeapMemoryUsage
12/15/2014 17:53:32 +0800 org.archive.jmx.Client NonHeapMemoryUsage:
committed: 82870272
init: 2555904
max: -1
used: 81061392
测试成功。
4.上传tomcat模版
ok。
