只执行某些测试用例

-t指定 执行哪些用例

liqiangdeMacBook-Pro:rediscluster liqiang$ redis-benchmark -h 127.0.0.1 -p 6379  -c 1 -q -t set,lpush
SET: 20964.36 requests per second
LPUSH: 20618.56 requests per second

直接指定命令

liqiangdeMacBook-Pro:rediscluster liqiang$ redis-benchmark -h 127.0.0.1 -p 6379  -c 1 -q script load "redis.call('set','foo','bar')"
script load redis.call('set','foo','bar'): 20811.65 requests per second

不同key测试

-r 多少个随机key  -n为set多少次 -t为只测set

liqiangdeMacBook-Pro:rediscluster liqiang$ redis-benchmark -h 127.0.0.1 -p 6379  -c 1 -r 10000 -n 100000 -t SET
====== SET ======
  100000 requests completed in 4.78 seconds
  1 parallel clients
  3 bytes payload
  keep alive: 1

100.00% <= 4 milliseconds
100.00% <= 11 milliseconds
100.00% <= 11 milliseconds
20903.01 requests per second

pipelining测试

-p 表示使用pipelining 1000条为一组测试

liqiangdeMacBook-Pro:rediscluster liqiang$ redis-benchmark -h 127.0.0.1 -p 6379  -c 1 -t set,get -P 1000 -q
SET: 473933.66 requests per second
GET: 1219512.12 requests per second

常用命令

慢日志

获取前五条慢日志

SLOWLOG GET 2

输出

# 获取 2 条作为示例
127.0.0.1:6379> SLOWLOG get 2
# 序号
1) 1) (integer) 47
	 # 时间戳
   2) (integer) 1668743666
   # 执行时间（单位是微秒）
   3) (integer) 13168
   # 命令及其参数
   4) 1) "hset"
      2) "/idents/Default"
      3) "tt-fc-dev01.nj"
      4) "1668743666"
   # 客户端IP和端口   
   5) "127.0.0.1:43172"
   6) ""
2) 1) (integer) 46
   2) (integer) 1668646906
   3) (integer) 13873
   4) 1) "hset"
      2) "/idents/Default"
      3) "10.206.16.3"
      4) "1668646906"

设置和查看慢日志阈值

5000(微秒)表示5ms

127.0.0.1:6379> config set slowlog-log-slower-than 5000
OK
127.0.0.1:6379> get slowlog-log-slower-than
(nil)
127.0.0.1:6379> config get slowlog-log-slower-than
1) "slowlog-log-slower-than"
2) "5000"
