zabbix监控 JVM

在Zabbix中，JMX监控数据的获取由专门的代理程序来实现,即Zabbix-Java-Gateway来负责数据的采集，Zabbix-Java-Gateway和JMX的Java程序之间通信获取数据

JMX在zabbix中的运行流程

1.Zabbix-Server找Zabbix-Java-Gateway获取Java数据
2.Zabbix-Java-Gateway找Java程序(zabbix-agent)获取数据
3.Java程序返回数据给Zabbix-Java-Gateway
4.Zabbix-Java-Gateway返回数据给Zabbix-Server
5.Zabbix-Server进行数据展示

安装JAVA-gateway

# 安装
[root@web02 ~]# rpm -ivh
https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/5.0/rhel/7/x86_64/zabbix-java-gateway-5.0.42-1.el7.x86_64.rpm

# 启动java-gateway
[root@web02 ~]# systemctl start zabbix-java-gateway

# 修改zabbix_server配置文件
[root@zabbix5-server ~]# vim /etc/zabbix/zabbix_server.conf
JavaGateway=172.16.1.8
JavaGatewayPort=10052
StartJavaPollers=5

# 重启zabbix-server
[root@zabbix5-server ~]# systemctl restart zabbix-server
