一個shell監控服務日誌的腳本

假設/var/log/a.log是某程序的log文件

他的內容是：

2012-07-27 18:12:17,788 INFO [com.kmsocial.search.websearch.WeiboPool:229] - Weibo pool running!

要求寫個腳本，若是超過2分鐘沒有產生新log則發送郵件給admin@localhost.localdomain

#!/bin/bash

LOGFILE="/var/log/a.log"

STARTNUM=`wc -l $LOGFILE`

mail_to_root(){

mail -s "weibo pool has some problem" root<<!

there has no logs in two minutes!

!

}

exec 6<"$LOGFILE"

while :

do

        NEWNUM=`wc -l $LOGFILE`

        if [ "$STARTNUM"_ = "$NEWNUM"_ ];then

                mail_to_root

        else

                STARTNUM=$NEWNUM

        fi

        while read -u 6 new_log

        do

                if echo "$new_log" | grep -q "Weibo pool running";then

                        while read -u 6 tmp

                        do

                                :

                        done

                        break

                else

                        mail_to_root

                fi

        done

        sleep 120

done

exec 6<&-
