日志关键字监控及邮件报警

find_error.sh 编写如下，在每个小时有新的告警则发送邮件。

todayday=$(date +%Y-%m-%d)

thismoment=$(date +"%Y-%m-%d %H")

echo $thismoment

prg=/home/hoho/logs

cd $prg

iserror=`grep '$thismoment'  catalina-${todayday}.out -C20|grep 'java.sql.SQLException: PooledConnection has already been closed'`

if [ ! -n "$iserror" ]; then

  echo "${thismoment} 不用报警" >> $prg/abc.txt

else

  echo "${thismoment} 报警" >> $prg/abc.txt

  echo "${thismoment}：java.sql.SQLException: PooledConnection has already been closed" |mail -s "生产报错" [mail_address]

fi
