redisで各データ型top-nのbigkeys情報を取得する
5656 ワード
需要:前に書いたスクリプトはredis最大のtop-nのbigkeysを取得し、データ型を区別していません.もし各データ型の前top-nのbigkeysに対して取得するならば?
db_ip=5.5.5.101
db_port=6379
password=abc123
cursor=0
cnt=100
new_cursor=0
function get_key()
{
redis-cli -h $db_ip -p $db_port -a $password scan $1 count $cnt > scan_tmp_result
new_cursor=`sed -n '1p' scan_tmp_result`
sed -n '2,$p' scan_tmp_result > scan_result
}
function get_keyinfo()
{
cat $1 |while read line
do
key_size=`redis-cli -h $db_ip -p $db_port -a $password memory usage $line`
key_type=`redis-cli -h $db_ip -p $db_port -a $password type $line`
echo $line $key_type $key_size >> "$key_type.txt"
done
}
get_key $cursor
get_keyinfo scan_result
while [ $cursor -ne $new_cursor ]
do
get_key $new_cursor
get_keyinfo scan_result
done
all_types="string list set hash zset"
for type in $all_types
do
echo "-----------top $1 $type data type-----------"
if [[ -f "$type.txt" ]];then
cat "$type.txt" | sort -nrk3 | sed -n "1,$1p"
else
echo "The instance does not have $type data type"
fi
done
rm -rf scan_tmp_result
rm -rf scan_result
rm -rf string.txt
rm -rf set.txt
テスト結果:
[redis@lxd-vm1 ~]$ sh get_type_top.sh 5
-----------top 5 string data type-----------
test2 string 12325
test string 1589
c_9 string 49
c_99 string 49
c_999 string 49
-----------top 5 list data type-----------
c list 885
b list 553
-----------top 5 set data type-----------
hello set 285
world set 71
-----------top 5 hash data type-----------
The instance does not have hash data type
-----------top 5 zset data type-----------
The instance does not have zset data type
