Linux下监听Tomcat进程运行情况

# func:自动监控tomcat脚本并且执行重启操作

# tomcat启动程序(这里注意tomcat实际安装的路径)

StartTomcat=/myzone/apache-tomcat-7.0.56/bin/startup.sh

TomcatCache=/myzone/apache-tomcat-7.0.56/tomcatCache

 
# 定义要监控的页面地址

WebUrl=http://localhost:8080/

 
# 日志输出

GetPageInfo=/myzone/apache-tomcat-7.0.56/null

TomcatMonitorLog=/myzone/apache-tomcat-7.0.56/TomcatMonitor.log
