zabbix 通过jmx监控tomcat
如题安装方法：自己百度
步骤如下：
[*]在Zabbix-Server上开启Zabbix-Java-gateway
我的zabbix是用yum安装的，那么zabbix-java-gateway也用yum来装
# rpm -i https://repo.zabbix.com/zabbix/3.5/rhel/7/x86_64/zabbix-release-3.5-1.el7.noarch.rpm --导入zabbix官方repo和key证书
# yum -y installjava-1.8.0Zabbix-Java-gateway
zabbix-server的环境：
--Zabbix-Server:
# ./version.sh
Using CATALINA_BASE: /usr/local/tomcat8
Using CATALINA_HOME: /usr/local/tomcat8
Using CATALINA_TMPDIR: /usr/local/tomcat8/temp
Using JRE_HOME: /usr/local/jdk1.8.0_181
Using CLASSPATH: /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jar

--至此zabbix-server端已经部署完成
[*]zabbix-agent端，也是tomcat服务器配置
--tomcat or jdk version:
# ./version.sh
Using CATALINA_BASE: /usr/local/tomcat8
Using CATALINA_HOME: /usr/local/tomcat8
Using CATALINA_TMPDIR: /usr/local/tomcat8/temp
Using JRE_HOME: /usr/local/jdk1.8.0_181
Using CLASSPATH: /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jar
Server version: Apache Tomcat/8.0.53
Server built: Jun 29 2018 14:42:45 UTC
Server number:8.0.53.0
OS Name: Linux
OS Version: 3.10.0-862.9.1.el7.x86_64
Architecture: amd64
JVM Version: 1.8.0_181-b13
JVM Vendor: Oracle Corporation
修改tomcat家目录下的bin目录下的catalina.sh文件，添加以下内容
# vim /usr/local/tomcat8/bin/catalina.sh
CATALINA_OPTS="-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.port=12345 --监听的端口
-Djava.rmi.server.hostname=192.168.22.8" -zabbix-server服务器ip
下载两个war包放到tomcat家目录下，用于监听用
http://repo.typesafe.com/typesafe/maven-releases/cmdline-jmxclient/cmdline-jmxclient/0.10.3/cmdline-jmxclient-0.10.3.jar --用于测试是否能获取数据用;
http://archive.apache.org/dist/tomcat/tomcat-7/v7.0.76/bin/extras/catalina-jmx-remote.jar --用于收集tomcat信息用，注意版本一定要和tomcat版本一致。
--注意重启tomcat，确定12345端口已监听
### 执行以下命令，看能否收集到数据
# java -jar cmdline-jmxclient-0.10.3.jar - localhost:12345 java.lang:type=Memory NonHeapMemoryUsage
08/03/2018 13:36:02 +0800 org.archive.jmx.Client NonHeapMemoryUsage:

[*]导入tomcat模板，添加jmx监控
下载tomcat_jvm_template：
# wget https://github.com/liuyjishg/DevOps/blob/master/zabbix/JVM_Tomcat_Template.zip

解压JVM_Tomcat_Template.zip文件，将里面的文件导入到zabbix模板中
再添加监控jmx就可以了
