篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了zabbix监控多个tomcat实例--自动发现相关的知识，希望对你有一定的参考价值。
参考：http://www.iyunv.com/thread-227674-1-1.html
1、上传 catalina-jmx-remote.jar,
cmdline-jmxclient-0.10.3.jar,
jmx_discovery.sh 和 add_service_tomcat.sh 到 /tmp/目录下
2、给 add_service_tomcat.sh 赋执行权限，并执行
执行完这个脚本之后，需要重启你的tomcat服务，和zabbix_agentd的服务
3 cat add_service_tomcat.sh 脚本内容
#，根据自己的情况各自改下你们安装tomcat的路径即可。

tomcat_no=`find /home/edu-*/*/bin/ -name catalina.sh|awk -F "/bin/catalina.sh" ‘{print $1}‘|wc -l`
n_port=12345 #配置监控初始端口
local_ip=`ifconfig eth0 |awk -F ‘[ :]+‘ ‘NR==2 {print $4}‘` #提取主机IP
for tomcat in $t_datadir

7 测试在服务端执行下面的命令
/usr/local/zabbix/bin/zabbix_get -s 127.0.0.1 -k java.jmx.discovery 测试 ip是客户端ip
返回下面这个即为正常

java -jar /home/soft/cmdline-jmxclient-0.10.3.jar - 58.116.1.2:12345 java.lang:type=Memory NonHeapMemoryUsage 07/10/2017 13:58:56 +0800 org.archive.jmx.Client NonHeapMemoryUsage: committed: 145186816 init: 2555904 max: -1 used: 141596768
第三个测试：
/home/usr/local/zabbix/bin/zabbix_get -s 58.116.7.248 -k java.HeapMemoryUsage.status[12346,max] 返回下面的值即为正常 1072168960
