    servrun=`netstat -pln|awk -F/ '/:80/{print $NF}'`

    ip=`ifconfig|awk '/cast/{print $2}'|awk -F: '{if(NR==1){a=$2}else if(NR==2){b=$2}}END{print b"-"a}'`
    data=`echo -e "ip:$ip\nloadavg/5min:$loadavg\tcacheuse%:$diskuse\tservice:$servrun"`
    diskper=`echo $diskuse|sed 's/%//'`

    num=`ps aux|grep check.sh|grep -v grep|wc -l`

    if [[ $num > 2 ]];then
        break 2
    fi

    if [[ $loadavg > 1.00 ]] &amp;&amp; [[ $diskper > 90 ]];then
        subject="warning-$ip-loadavg-disk"
