[root@test ~]# redis-benchmark --help \r\nUsage: redis-benchmark [-h \n \n ] [-p \n \n ] [-c \n \n ] [-n \n \n [-k \n \n ] -h \n \n Server hostname (default 127.0.0.1) -p \n \n Server port (default 6379) -s \n \n Server socket (overrides host and port) -a \n \n Password for Redis Auth -c \n \n Number of parallel connections (default 50) -n \n \n Total number of requests (default 100000) -d \n \n Data size of SET\/GET value in bytes (default 2) -dbnum \n \n SELECT the specified db number (default 0) -k \n \n 1=keep alive 0=reconnect (default 1) -r \n \n Use random keys for SET\/GET\/INCR, random values for SADD Using this option the benchmark will expand the string __rand_int__ inside an argument with a 12 digits number in the specified range from 0 to keyspacelen-1. The substitution changes every time a command is executed. Default tests use this to hit random keys in the specified range. -P \n \n Pipeline \n \n requests. Default 1 (no pipeline). -q Quiet. Just show query\/sec values --csv Output in CSV format -l Loop. Run the tests forever -t \n \n Only run the comma separated list of tests. The test names are the same as the ones produced as output. -I Idle mode. Just open N idle connections and wait. Examples: Run the benchmark with the default configuration against 127.0.0.1:6379: $ redis-benchmark Use 20 parallel clients, for a total of 100k requests, against 192.168.1.1: $ redis-benchmark -h 192.168.1.1 -p 6379 -n 100000 -c 20 Fill 127.0.0.1:6379 with about 1 million keys only using the SET test: $ redis-benchmark -t set -n 1000000 -r 100000000 Benchmark 127.0.0.1:6379 for a few commands producing CSV output: $ redis-benchmark -t ping,set,get -n 100000 --csv Benchmark a specific command line: $ redis-benchmark -r 10000 -n 10000 eval 'return redis.call(\"ping\")' 0 Fill a list with 10000 random elements: $ redis-benchmark -r 10000 -n 10000 lpush mylist __rand_int__ On user specified command lines __rand_int__ is replaced with a random integer with a range of values selected by the -r option.\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n <\/pre>\n<\/p>\n
