通过判断test.jsp页面的返回值，来确定tomcat状态

#!/bin/sh

sleep 2

 

tom=`cat test.jsp`

     echo "`date +%d/%m/%Y:%H:%M:%S` - - tomcatserver is ok!"

     echo "`date +%d/%m/%Y:%H:%M:%S` - - tomcatserver is down!restart is successful!"

     curl "http://sms.api.bz/fetion.php?username=150********&password=******&sendto=150********&message=tomcat服务器down机，重启成功！"

另外一个监控内存的段落

1. #!/bin/sh   
2. MEM=`ps aux|grep tomcat|grep startup|awk '{print $6}'`   
3. #echo $MEM  
4. if [ $MEM -gt 800000 ]; then   
5.    echo "tomcat mem too large,restart tomcat!"  
6.    service tomcat restart   
7. fi
