zabbix-基于Java Gateway监控Tomcat

环境准备

zabbix server：192.168.61.111  配置文件指定java gateway地址和端口连接gateway 10052端口获取数据

java gateway：192.168.64.111  创建主机代理JMX，指定IP+端口收集被监控主机数据

tomcat：192.168.64.112     监听12345端口发送数据给java gateway，同时主动发送其他数据给proxy

zabbix proxy： 192.168.64.112  主动模式下从server获取监控项，同时等待agent获取监控项并收集agent发送数据，存储到本地MySQL，定期发送给server；

                                                    同时proxy获取到java监控项，由gateway定期从后端获取监控数据后，发送给proxy，proxy定期发送给server。

安装

[root@zabbix-server ~]# yum -y install zabbix-java-gateway.x86_64

 修改javagateway配置文件

[root@zabbix-server alertscripts]# grep "^[a-Z]" /etc/zabbix/zabbix_java_gateway.conf

TIMEOUT=30  # 超时时间

 启动

[root@zabbix-server alertscripts]# systemctl  start zabbix-java-gateway.service
[root@zabbix-server alertscripts]# systemctl  enable  zabbix-java-gateway.service
