#
# 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：Tomcat安装与配置
#zabbix 安装参考：zabbix安装和基本介绍

#安装java gateway
[[email protected] ~]# yum install -y zabbix-java-gateway java-1.8.0
#配置
[[email protected] ~]# vim /etc/zabbix/zabbix_java_gateway.conf [[email protected] ~]# 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 [[email protected] ~]#
我们使用默认配置即可
#开启服务
[[email protected] ~]# systemctl start zabbix-java-gateway.service [[email protected] ~]# netstat -lntup | grep 10052 tcp6 0 0 :::10052 :::* LISTEN 3002/java [[email protected] ~]#
#修改zabbix-server配置文件
[[email protected] ~]# vim /etc/zabbix/zabbix_server.conf [[email protected] ~]# egrep '(^Java|^Start)' /etc/zabbix/zabbix_server.conf JavaGateway=192.168.174.136 JavaGatewayPort=10052 StartJavaPollers=5
#重启zabbix-server服务
[[email protected] ~]# systemctl restart zabbix-server.service
#Tomcat开启JMX
#参考文档:http://tomcat.apache.org/tomcat-8.0-doc/monitoring.html
