zabbix 监控 Tomcat

heberoxx · 发表于 2018-11-30 10:12:10

　　#
　　# 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
　　

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

[root@node2 ~]# yum install -y zabbix-java-gateway java-1.8.0　　

　　#配置
[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
[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

[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
[root@node2 ~]# systemctl restart zabbix-server.service　　

　　#Tomcat开启JMX
　　#参考文档:http://tomcat.apache.org/tomcat-8.0-doc/monitoring.html
