 Find out the highest cpu consumed threads of java, and print the stack of these threads.
 Example: ${PROG} -c

　　　　在tomcat中执行脚本

　　　　

　　　　会这样显示

二,　　zabbix服务端配置

　　　　　　在清华源下载zabbix-java-getway

　　　　　　rpm -ivh https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-java-gateway-4.0.0-2.el7.x86_64.rpm

　　　　

　　　　再次安装依赖

　　　　

　　　　yum install -y zabbix-java-gateway-4.0.0-2.el7.x86_64

　　　　

　　　　启动服务

　　　　systemctl enable zabbix-java-gateway.service

　　　　systemctl start zabbix-java-gateway.service

　　　　systemctl status zabbix-java-gateway.service

　　　　

　　　　

　　　　重启服务器

　　　　systemctl restart zabbix-java-gateway.service

三, 客户端配置

　　　　安装zabbix -agent

　　　　rpm -ivh https://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

　　　　yum install zabbix-agent -y

　　　　

　　　　配置被监控项

　　　　vim  /application/tomcat/bin/catalina.sh +97

　　　　CATALINA_OPTS="$CATALINA_OPTS
　　　　-Dcom.sun.management.jmxremote
　　　　-Dcom.sun.management.jmxremote.port=12345  
　　　　-Dcom.sun.management.jmxremote.authenticate=false
　　　　-Dcom.sun.management.jmxremote.ssl=false
　　　　-Djava.rmi.server.hostname=10.0.0.11"

　　　　重新启动

　　　　 systemctl start zabbix-agent.service

四,web界面添加

　　　　添加主机

　　　　

　　　　完成后添加模板等待就行
