monotonic: x86 linux, kernel clocksource is unknown, not using TSCUsage: valkey-benchmark [OPTIONS] [--] [COMMAND ARGS...]
Simulates sending commands using multiple clients. The utility provides a
default set of tests. You can run a subset of the tests using the -t option or
supply one or more custom commands on the command line.
To supply multiple commands on the command line, separate them with ';' as in
`SET foo bar ';' GET foo`. You can also prefix a command in the sequence with
a number N to repeat the command N times. In command arguments, the following
placeholders are substituted:
__rand_int__ Replaced with a zero-padded random integer in the range
selected using the -r option. Multiple occurrences within the
command will have different values.
__rand_1st__ Like __rand_int__ but multiple occurrences will have the same
value. __rand_2nd__ through __rand_9th__ are also available.
__data__ Replaced with data of the size specified by the -d option.
{tag} Replaced with a tag that routes the command to each node in
a cluster. Include this in key names when running in cluster
mode.
Options:
-h <hostname> Server hostname (default 127.0.0.1)
-p <port> Server port (default 6379)
-s <socket> Server socket (overrides host and port)
-a <password> Password for Valkey Auth
--user <username> Used to send ACL style 'AUTH username pass'. Needs -a.
-u <uri> Server URI on format valkey://user:password@host:port/dbnum
User, password and dbnum are optional. For authentication
without a username, use username 'default'. For TLS, use
the scheme 'valkeys'.
-c <clients> Number of parallel connections (default 50).
Note: If --cluster is used then number of clients has to be
the same or higher than the number of nodes.
-n <requests> Total number of requests (default 100000)
--duration <seconds>
Run benchmark for specified number of seconds
(mutually exclusive with -n)
--warmup <seconds> Run benchmark for specified warmup period before
recording data
-d <size> Data size of SET/GET value in bytes (default 3)
--dbnum <db> SELECT the specified db number (default 0)
-3 Start session in RESP3 protocol mode.
--threads <num> Enable multi-thread mode.
--cluster Enable cluster mode.
If the command is supplied on the command line in cluster
mode, the key must contain "{tag}". Otherwise, the
command will not be sent to the right cluster node.
--rfr <mode> Enable read from replicas in cluster mode.
This command must be used with the --cluster option.
There are three modes for reading from replicas:
'no' - sends read requests to primaries only (default)
'yes' - sends read requests to replicas only.
'all' - sends read requests to all nodes.
Since write commands will not be accepted by replicas,
it is recommended to enable read from replicas only for read
command tests.
--enable-tracking Send CLIENT TRACKING on before starting benchmark.
-k <boolean> 1=keep alive 0=reconnect (default 1)
-r <keyspacelen> Use random keys for SET/GET/INCR, random values for SADD,
random members and scores for ZADD.
Using this option the benchmark will replace the string
__rand_int__ inside an argument with a random 12 digit
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.
Note: If -r is omitted, all commands in a benchmark will
use the same key.
--sequential Modifies the -r argument to replace the string __rand_int__
with 12 digit numbers sequentially instead of randomly.
__rand_1st__ through __rand_9th__ are available with
independent counters. Used to create expected number of
elements with multiple replacements.
example: ZADD myzset __rand_int__ element:__rand_1st__
-P <numreq> Pipeline <numreq> requests. That is, send multiple requests
before waiting for the replies. Default 1 (no pipeline).
When multiple commands are specified on the command line,
then the full command sequence counts as one and -P controls
the number of times the command sequence is sent in each
pipeline.
-q Quiet. Just show query/sec values
--precision Number of decimal places to display in latency output
(default 0)
--csv Output in CSV format
-l Loop. Run the tests forever
-t <tests> Only run the comma separated list of tests. The test
names are the same as the ones produced as output.
The -t option is ignored if a specific command is supplied
on the command line.
-I Idle mode. Just open N idle connections and wait.
-x Read last argument from STDIN.
--rps <requests> Limit the total number of requests per second.
Default 0 (no limit)
--seed <num> Set the seed for random number generator.
Default seed is based on time.
--num-functions <num>
Sets the number of functions present in the Lua lib that is
loaded when running the 'function_load' test. (default 10).
--num-keys-in-fcall <num>
Sets the number of keys passed to FCALL command when running
the 'fcall' test. (default 1)
--tls Establish a secure TLS connection.
--sni <host> Server name indication for TLS.
--cacert <file> CA Certificate file to verify with.
--cacertdir <dir> Directory where trusted CA certificates are stored.
If neither cacert nor cacertdir are specified, the default
system-wide trusted root certs configuration will apply.
--insecure Allow insecure TLS connection by skipping cert validation.
--cert <file> Client certificate to authenticate with.
--key <file> Private key file to authenticate with.
--tls-ciphers <list> Sets the list of preferred ciphers (TLSv1.2 and below)
in order of preference from highest to lowest separated by
colon (":"). See the ciphers(1ssl) manpage for more
information about the syntax of this string.
--tls-ciphersuites <list> Sets the list of preferred ciphersuites (TLSv1.3)
in order of preference from highest to lowest separated by
colon (":"). See the ciphers(1ssl) manpage for more
information about the syntax of this string, and
specifically for TLSv1.3 ciphersuites.
--mptcp Enable an MPTCP connection.
--fuzz Enable fuzzy mode to generate random commands. WARNING: Recommended for testing only, not for use with production data.
--fuzz-mode <modes> Set fuzzing modes (comma-separated): malformed-commands, config-commands.
malformed-commands: Generates also malformed commands.
config-commands: Allows CONFIG SET commands.
Default: valid commands only.
--fuzz-loglevel <level>
Set log level for fuzzer (none, error, info, debug).
Default is 'info'.
--help Output this help and exit.
--version Output version and exit.
Examples:
Run the benchmark with the default configuration against 127.0.0.1:6379:
$ valkey-benchmark
Use 20 parallel clients, for a total of 100k requests, against 192.168.1.1:
$ valkey-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:
$ valkey-benchmark -t set -n 1000000 -r 100000000
Benchmark 127.0.0.1:6379 for a few commands producing CSV output:
$ valkey-benchmark -t ping,set,get -n 100000 --csv
Benchmark a specific command line:
$ valkey-benchmark -r 10000 -n 10000 eval 'return server.call("ping")' 0
Fill a list with 10000 random elements:
$ valkey-benchmark -r 10000 -n 10000 lpush mylist __rand_int__
Benchmark a specific transaction:
$ valkey-benchmark -- multi ';' set key:__rand_int__ __data__ ';' \
incr counter ';' exec
