# 一、Zabbix 监控Tomcat #

### 1、需要安装的软件： ###

*  jdk-8u121-linux-x64.rpm
 *  Zabbix-Java-Gateway
 *  cmdline-jmxclient.jar工具

### 2、Zabbix的JMX监控架构 ###

### 3、组件关系示意图： ###

当`Zabbix-Server`需要知道java应用程序的某项性能的时候，会启动自身的一个`Zabbix-JavaPollers`进程去连接`Zabbix-JavaGateway`请求数据，而`ZabbixJavagateway`收到请求后使用“`JMXmanagementAPI`”去查询特定的应用程序，而前提是应用程序这端在开启时需要“`-Dcom.sun.management.jmxremote`”参数来开启JMX远程查询就行。Java程序会启动自身的一个简单的小程序端口`12345`向`Zabbix-JavaGateway`提供请求数据。

**配置Zabbix监控Java应用程序的关键点在于：配置Zabbix-JavaGateway、让Zabbix-Server能够连接Zabbix-JavaGateway、Tomcat开启JVM远程监控功能等**

# 二、搭建实验环境 #

<table> 
 <thead> 
  <tr> 
   <th>主机名（IP）</th> 
   <th>服务</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>server1(172.25.2.1)</td> 
   <td>zabbix-server ，zabbix-web，zabbix-agent，java-gateway</td> 
  </tr> 
  <tr> 
   <td>server2(172.25.2.2)</td> 
   <td>zabbix-agent，tomcat</td> 
  </tr> 
 </tbody> 
</table>

我们可以看到此时，zabbix平台还没有监控server2上面的java应用

**1.安装tomcat和jdk**  
在server2（agent的客户端）上安装tomcat和jdk,并打开tomcat：

[root@server2 ~]#rpm -ivh jdk-8u121-linux-x64.rpm 
    [root@server2 ~]#tar zxf apache-tomcat-8.5.24.tar.gz -C /usr/local/
    [root@server2 ~]#cd /usr/local/
    [root@server2 local]#ln -s apache-tomcat-8.5.24 tomcat
    [root@server2 ~]#vim /usr/local/tomcat/bin/catalina.sh	#向tomcat中添加JMX的参数 
    
    CATALINA_OPTS='-Dcom.sun.management.jmxremote   #开启远程监控
    -Dcom.sun.management.jmxremote.port=8888	#监听端口号，方便远程访问
    -Dcom.sun.management.jmxremote.ssl=false	#是否对连接开启SSL加密，默认开启
    -Dcom.sun.management.jmxremote.authenticate=false'	#是否需要开启用户认证,默认开启

补充：`JMX`全称`Java Management Extensions`, 为Java应用提供管理扩展功能

[root@server2 local]#cd tomcat/
    [root@server2 local]#cd bin/
    [root@server2 bin]#./startup.sh	#启动tomcat

**2.安装zabbix-java-gateway**  
server1（zabbix\_server端）安装zabbix-java-gateway，并做相应配置：

[root@server1 ~]#yum install zabbix-java-gateway-4.4.1-1.el7.x86_64.rpm -y
    [root@server1 ~]#systemctl start zabbix-java-gateway
    [root@server1 ~]#netstat -antlp | grep 10052
    [root@server1 ~]#vim /etc/zabbix/zabbix_server.conf 
    288 JavaGateway=172.25.254.1
    296 JavaGatewayPort=10052
    304 StartJavaPollers=5
    [root@server1 ~]#systemctl restart zabbix-server

**3.zabbix监控界面进行相应设置**  
step1 配置—主机—server2

step3 配置—主机—模版—取消链接并清理

step4 配置—主机—模版—添加—Java JMX—更新

step5 查看到server2此时JMX图标为灰色

step6

vim /etc/zabbix/zabbix_java_gateway.conf 
    
      9 LISTEN_IP="172.25.254.1"
     17 LISTEN_PORT=10052
     35 START_POLLERS=5
    
    systemctl restart zabbix-java-gateway
