redis的监控
1)查看key
>keys * #查看所有的key,数据量大的时候容易阻塞
>scan 0 #每次获取11个key，直到获取所有的key,编号从0开始，下一次获取时，按照提示的编号输入scan后的值
当编号再次为0时，获取完成所有数据
[redis@t4-dtpoc-dameng-db-damengdb01-ma01 bin]$ ./redis-cli -a passw0rd
127.0.0.1:6379> keys *
1) "name1"
2) "name"
3) "colour"
4) "list"
5) "id"
6) "mobile"
7) "money"
8) "jsj"
9) "sjaf"
10) "read"
11) "jj"
12) "sss"

4) "sss"
5) "colour"
6) "list"
7) "sjaf"
8) "read"
9) "jj"
10) "money"
127.0.0.1:6379> scan 7
1) "0"
2) 1) "id"
2) "mobile"
2)redis-cli -a redispwd --stat #监控redis的状态
[redis@t4-dtpoc-dameng-db-damengdb01-ma01 bin]$ ./redis-cli -a passw0rd --stat

显示多少个key,内存占多少，客户端有多少，请求数是多少，连接数是多少
通过增加客户端及key的操作可以发现变化
3)redis-cli -a redispwd monitor #监控数据操作
操作的命令，增加，删除等都会监控到
