Zabbix使用JMX监控tomcat

1.安装tomcat和jdk

[[email protected] ~]# ls
apache-tomcat-8.5.24.tar.gz  jdk-8u121-linux-x64.rpm  zabbix-agent-4.0.5-1.el7.x86_64.rpm
[[email protected] ~]# rpm -ivh jdk-8u121-linux-x64.rpm 
[[email protected] ~]# tar zxf apache-tomcat-8.5.24.tar.gz -C /usr/local

[[email protected] ~]# cd /usr/local
[[email protected] local]# ls
apache-tomcat-8.5.24  bin  etc  games  include  lib  lib64  libexec  sbin  share  src

2.制作软连接

[[email protected] local]# ln -s apache-tomcat-8.5.24/ tomcat
[[email protected] local]# ls
apache-tomcat-8.5.24  etc    include  lib64    sbin   src
bin                   games  lib      libexec  share  tomcat
[[email protected] local]# cd tomcat/
[[email protected] tomcat]# ls
bin  conf  lib  LICENSE  logs  NOTICE  RELEASE-NOTES  RUNNING.txt  temp  webapps  work
[[email protected] tomcat]# cd bin/
[[email protected] bin]# ls

3.向tomcat中添加JVM的参数

[[email protected] bin]# vim catalina.sh

110 CATALINA_OPTS='-Dcom.sun.management.jmxremote
111   -Dcom.sun.management.jmxremote.port=8888
112   -Dcom.sun.management.jmxremote.ssl=false
113   -Dcom.sun.management.jmxremote.authenticate=false'
[[email protected] bin]# ./startup.sh 
[[email protected] bin]# netstat -tnlp

4.server1： 安装zabbix_java_gateway并做相应的配置

[[email protected] ~]# cd 4.0/
[[email protected] 4.0]# ls
[[email protected] 4.0]# yum install -y zabbix-java-gateway-4.0.5-1.el7.x86_64.rpm 

[[email protected] 4.0]# cd /etc/zabbix/
[[email protected] zabbix]# ls
web             zabbix_agentd.conf  zabbix_java_gateway.conf         zabbix_server.conf
zabbix_agentd.  zabbix_agentd.d     zabbix_java_gateway_logback.xml
[[email protected] zabbix]# vim zabbix_java_gateway.conf   ##查看一下
 
[[email protected] zabbix]# vim zabbix_server.conf  ##修改内容如下
288 JavaGateway=172.25.19.1
296 JavaGatewayPort=10052
304 StartJavaPollers=5

5.开启服务

[[email protected] zabbix]# systemctl start zabbix-java-gateway

[[email protected] zabbix]# 
[[email protected] zabbix]# netstat -tnlp

[[email protected] zabbix]# zabbix_server -R config_cache_reload
zabbix_server [12968]: command sent successfully
[[email protected] zabbix]# 
[[email protected] zabbix]# systemctl restart zabbix-server

6.zabbix监控页面进行相应的配置

• 配置—> 主机—> server2—> 主机—> 添加JMX接口的信息（端口要和配置文件中写的一样） —> 添加
  
• 主机 —> 模板—> 选择图中的模板 —> 添加 —> 更新
  
  
• server2 —> 图形—> file descriptors—> 预览
  
  
• 刷新以下可以看到server2的JMX变绿
