# zabbix提供了一个JMX通过java gateway 来监控java
#官方文档：https://www.zabbix.com/documentation/3.2/manual/appendix/config/zabbix_java
#java gatewa 需要独立安装 以为zabbix-server zabbix-agent都不能直接监控java
#Tomcat 安装参考：
#zabbix 安装参考：
| 主机名 | 角色 | IP地址 |
| node2 | zabbix-server zabbix-java-gateway | 192.168.174.136 |
| node4 | tomcat | 192.168.174.138 |
#安装java gateway
| 1 | [root@node2 ~] # yum install -y zabbix-java-gateway java-1.8.0 |
#配置
| 1 2 3 4 5 6 7 8 | [root@node2 ~] # vim /etc/zabbix/zabbix_java_gateway.conf [root@node2 ~] # grep '^[a-Z]' /etc/zabbix/zabbix_java_gateway.conf LISTEN_IP= "0.0.0.0" LISTEN_PORT=10052 PID_FILE= "/var/run/zabbix/zabbix_java.pid" START_POLLERS=5 TIMEOUT=3 [root@node2 ~] # |
我们使用默认配置即可
#开启服务
| 1 2 3 4 | [root@node2 ~] # systemctl start zabbix-java-gateway.service [root@node2 ~] # netstat -lntup | grep 10052 tcp6 0 0 :::10052 :::* LISTEN 3002 /java [root@node2 ~] # |
#修改zabbix-server配置文件
| 1 2 3 4 5 | [root@node2 ~] # vim /etc/zabbix/zabbix_server.conf [root@node2 ~] # egrep '(^Java|^Start)' /etc/zabbix/zabbix_server.conf JavaGateway=192.168.174.136 JavaGatewayPort=10052 StartJavaPollers=5 |
#重启zabbix-server服务
| 1 | [root@node2 ~] # systemctl restart zabbix-server.service |
#Tomcat开启JMX
