分析某個時間段內，表的select、insert、update、delete次數。需要用到percona-toolkit包中的一個工具pt-query-digest，腳本如下：
[root@syk ~]# cat get_list.sh
#!/bin/bash
set -x
#slow_file=ai-db1-slow.log
slow_file=$1
if [ $# != 1 ] ; then
echo "USAGE: $0 slow.log"
echo " e.g.: $0 api-db1-slow.log"
exit 1;
fi
pt-query-digest --limit 10000 $slow_file > /tmp/tmp_file
bn=`grep -n "# 1 0x" /tmp/tmp_file|awk -F ':' '{print $1}'`
tn=`grep -n "# Query 1:" /tmp/tmp_file |awk -F ':' '{print $1}'`
en=`expr $tn - 2`
sed -n "$bn,$en"p /tmp/tmp_file > /tmp/table_file
cat /tmp/table_file|awk '{print $6","$9","$10}' > /tmp/table_source
/usr/local/mysql/bin/mysql -uroot -pxxxxxxxx -S /tmp/mysql_3308.sock <<EOF
