.SH NAME
redis\-benchmark \- Redis benchmark

.SH SYNOPSIS
.B redis\-benchmark
[ options ]
.LP

.SH DESCRIPTION
\fBRedis\fP is an open source (BSD licensed), in-memory data structure store,
used as database, cache and message broker, found at
.B http://redis.io/

The \fBredis\-benchmark\fP command is a command to benchmark redis-server.

.SH OPTIONS
.TP 15
.B \-h \fIhostname\fP
Server hostname (default: 127.0.0.1).
.TP
.B \-p \fIport\fP
Server port (default: 6379).
.TP
.B \-s \fIsocket\fP
Server socket (overrides hostname and port).
.TP
.B \-a \fIpassword\fP
Password to use when connecting to the server.
.TP
.B \-c \fIclients\fP
Number of parallel connections (default 50)
.TP
.B \-dnnum \fIdb\fP
SELECT the specified db number (default 0)
.TP
.B \-k \fIboolean\fP
1=keep alive 0=reconnect (default 1)
.TP
.B \-r \fIkeyspacelen\fP
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.
.TP
.B \-P \fInumreq\fP
Pipeline <numreq> requests. Default 1 (no pipeline).
.TP
.B \-e
If server replies with errors, show them on stdout.
(no more than 1 error per second is displayed)
.TP
.B \-q
Quiet. Just show query/sec values
.TP
.B \-\-csv
Output in CSV format
.TP
.B \-l
Loop. Run the tests forever
.TP
.B \-t \fItests\fP
Only run the comma separated list of tests. The test
names are the same as the ones produced as output.
.TP
.B \-I
Idle mode. Just open N idle connections and wait.

.SH EXAMPLES
.TP 5
Run the benchmark with the default configuration against 127.0.0.1:6379:
$ redis\-benchmark
.TP
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
.TP
Fill 127.0.0.1:6379 with about 1 million keys only using the SET test:
$ redis\-benchmark \-t set \-n 1000000 \-r 100000000
.TP
Benchmark 127.0.0.1:6379 for a few commands producing CSV output:
$ redis\-benchmark \-t ping,set,get \-n 100000 \-\-csv
.TP
Benchmark a specific command line:
$ redis\-benchmark \-r 10000 \-n 10000 eval 'return redis.call("ping")' 0
.TP
Fill a list with 10000 random elements:
$ redis\-benchmark \-r 10000 \-n 10000 lpush mylist __rand_int__
.TP
On user specified command lines __rand_int__ is replaced with a random integer
with a range of values selected by the -r option.
