通过shell脚本监控tomcat运行情况

记录关于通过shell脚本监控tomcat运行情况

近期项目需要，磕磕绊绊写了几个shell脚本监控自己的程序是否正常运行，首先在应用代码中增加固定格式的日志，并记录当前时间，可以使shell脚本获取到日志中最新一条的日志记录，获取到时间并跟系统当前时间对比，如超过设置的阈值，如5分钟，则执行重启或发送预警邮件。

• 1.通过脚本重启tomcat

#!/bin/sh
cd /appl/datarcv/importDB/apache-tomcat-7.0.61/bin
sh shutdown.sh
if [ $? -eq 0 ];then
    pid=$(ps -ef | grep apache-tomcat | grep -v grep | awk '{print $2}')
fi
if [ -n "$pid" ];then
        echo "tomcat process id: $pid"
        kill -9 ${pid}
else
    echo "tomcat process not exist,begin to start"
        sh startup.sh
        exit;
fi
if [ $? -eq 0 ];then
        echo "tomcat stop success,bengin to start"
        sh startup.sh
else
        echo "tomcat stop fail"
fi

• 2.通过shell脚本监控tomcat固定日志的输出，达到tomcat应用monitor的效果

cd /appl/datarcv/importDB/log
#get time from info.log
logtime=$(grep -n '_run_ok' info.log | tail -n 1|awk '{print $9}')
echo "logTime:"${logtime}
nowTime=`date +%s`
echo "nowTieme:"${nowTime}
interval=`expr $nowTime - $logtime`
echo $interval
if [ $interval -gt 300 ];then
        echo "restart tomcat"
        cd /appl/datarcv/bin
        sh restartTomcat.sh
        mailx -s "Cn002 tomcat error,will restart,please check again."  [email protected] < monitor.log
