zabbix server 安装时需要启动JAVA Gateway
zabbix server 配置启动 JAVA Gateway
zabbix server 配置 JAVA Gateway/JAVA GatewayPort参数
zabbix server 配置 StartJavaPollers参数
保障zabbix server和JMX 应用的IP+Port通信
开启并正确配置JMX
ZabbixServer向Zabbix Java Gateway 组件发起获取数据请求,Java Gateway收到请求后会向被监控的Java 应用发起数据请求。
被监控端收到请求,并且响应对应的监控数据。Zabbix Java Gateway收到数据后,会返回给ZabbixServer。
