Redis相關的小工具：redis-load、redis-stat

標籤：redis   監控工具   壓力測試   

redis-load、redis-stat是Redis作者antirez寫的兩個小工具，其中：

• redis-load是Redis的一個壓力測試工具
• redis-stat是Redis的狀態監控工具

相關代碼見：https://github.com/antirez/redis-tools

1 下載代碼

$ git clone https://github.com/antirez/redis-tools.git

2 編譯

$ cd redis-tools$ make all

3 redis-load

redis-load是Redis壓力測試工具，可以通過下面的方式查看具體用法：

$ ./redis-load helpUsage: redis-load ... options ......

一個簡單的測試例子：

$ ./redis-load host 127.0.0.1 port 6379PRNG seed is: 3312712080 - use the ‘seed‘ option to reproduce the same sequence====== Report ======  10000 requests in 0.367 seconds  27247.96 requests per second  50 parallel clients  payload: 1..64 bytes  keep alive: 1  4.30% < 1 ms 79.07% < 2 ms 93.99% < 3 ms 98.53% < 4 ms 99.02% < 5 ms 99.24% < 6 ms 99.45% < 8 ms 99.50% < 9 ms 99.54% < 16 ms 99.58% < 17 ms 99.63% < 18 ms 99.66% < 19 ms 99.72% < 20 ms 99.78% < 21 ms 99.84% < 22 ms 99.90% < 23 ms 99.93% < 24 ms 99.95% < 25 ms100.00% < 26 ms

4 redis-stat

redis-stat是即時監控Redis執行個體的狀態，包括overview、vmstat、vmpage、ondisk-size、latency，具體資訊如下：

$ ./redis-stat helpUsage: redis-stat <type> ... options ...Statistic types: overview (default)   Print general information about a Redis instance. vmstat               Print information about Redis VM activity. vmpage               Try to guess the best vm-page-size for your dataset. ondisk-size          Stats and graphs about values len once stored on disk. latency              Measure Redis server latency.Options: host <hostname>      Server hostname (default 127.0.0.1) port <hostname>      Server port (default 6379) delay <milliseconds> Delay between requests (default: 1000 ms, 1 second). samplesize <keys>    Number of keys to sample for ‘vmpage‘ stat. logscale             User power-of-two logarithmic scale in graphs.

一個簡單的測試例子：

$ ./redis-stat host 127.0.0.1 port 6379------- data ------ --------------------- load -------------------- - child -keys       mem      clients blocked requests            connections          29602      3.45M    1       0       30090 (+0)          157         29602      3.45M    1       0       30091 (+1)          157         29602      3.45M    1       0       30092 (+1)          157         29602      3.45M    1       0       30093 (+1)          157         29602      3.45M    1       0       30094 (+1)          157         29602      3.45M    1       0       30095 (+1)          157         29602      3.45M    1       0       30096 (+1)          157         29602      3.45M    1       0       30097 (+1)          157         29602      3.45M    1       0       30098 (+1)          157......

查看Redis執行個體的即時的latency也非常有用：

$ ./redis-stat latency host 127.0.0.1 port 6379 1: 0.23 ms2: 0.67 ms3: 0.21 ms4: 0.23 ms5: 0.23 ms6: 0.16 ms7: 0.37 ms......
