tomcat performance monitoring

A while ago, the leader asked to use Zabbix to monitor multiple tomcat instances on a single machine. When starting to do, it is found that more data are less how to reaming Tomcat, and there are few instructions on how to monitor multiple tomcat. Arduous, finally fix, may still have some incomplete place, but the right when is guide, know the idea, the rest depe
