bigkeys

redis-client.exe --bigkeys

PS D:\RedisCache> .\redis-cli.exe --bigkeys

# Scanning the entire keyspace to find biggest keys as well as
# average sizes per key type.  You can use -i 0.1 to sleep 0.1 sec
# per 100 SCAN commands (not usually needed).

統計當前redis中所有key值數量大小，大小百分比。

stat

PS D:\RedisCache> .\redis-cli.exe --stat

實時查看redis的keys(key數量)、mem(內存占用大小)、clients(客戶端連接數)、blocked(鎖定數)、requests(請求總數)、connections(連接總次數)。

這些統計信息復位使用config resetstat
