1、tomcat上开启监控
下载 catalina-jmx-remote.jar 保存到tomcat/lib 目录下
编辑tomcat/bin/setenv.sh 添加如下
CATALINA_OPTS=”-Dcom.sun.management.jmxremote.port=8088 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Djava.rmi.server.hostname=192.168.15.84″
2、使用VisualVm测试监控tomcat,效果如下如果可以通过VisualVM监控tomcat说明tomcat配置正确
3、Zabbix server支持java
在编译安装zabbix前必须先配置好jdk并启用–enable-java 编译参数,具体如下
./configure –prefix=/usr/local/zabbix
–enable-server /
–enable-java /
–enable-agent /
–enable-proxy /
–with-mysql=/usr/local/mysql/bin/mysql_config /
–with-libcurl /
–with-libxml2 /
–with-ldap
在zabbix 服务器上开启zabbix java gateway
vim /usr/local/zabbix/sbin/zabbix_java/settings.sh
启动 java gateway
编辑zabbix server配置并重启服务
vim /usr/local/zabbix/etc/zabbix_server.conf
4、被监控服务器添加jvm监控
自定义监控
使用cmdline-jmxclient-0.10.3.jar工具查看tomcat中有哪些可监控项,然后根据实际情况自定义监控模板
列出所有项目:java -jar cmdline-jmxclient-0.10.3.jar – 192.168.15.84:8088 ,结果类似如下
获取堆内存信息:
java -jar cmdline-jmxclient-0.10.3.jar – 192.168.15.84:8088 java.lang:type=Memory HeapMemoryUsage
获取栈内存信息:
