stress

Overview ¶

Command stress is a tool to stress/load test RPC by issuing randomly generated requests.

Usage:

stress [flags] <command>

The stress commands are:

stress      Run stress test
stats       Print out stress stats of servers
load        Run load test
stop        Stop servers
help        Display help for commands or topics

The global flags are:

-alsologtostderr=true
  log to standard error as well as files
-log_backtrace_at=:0
  when logging hits line file:N, emit a stack trace
-log_dir=
  if non-empty, write log files to this directory
-logtostderr=false
  log to standard error instead of files
-max_stack_buf_size=4292608
  max size in bytes of the buffer to use for logging stack traces
-metadata=<just specify -metadata to activate>
  Displays metadata for the program and exits.
-stderrthreshold=2
  logs at or above this threshold go to stderr
-time=false
  Dump timing information to stderr before exiting the program.
-v=0
  log level for V logs
-v23.credentials=
  directory to use for storing security credentials
-v23.namespace.root=[/(dev.v.io:r:vprod:service:mounttabled)@ns.dev.v.io:8101]

-v23.permissions.file=
  specify a perms file as <name>:<permsfile>
-v23.permissions.literal=
  explicitly specify the runtime perms as a JSON-encoded access.Permissions.
  Overrides all --v23.permissions.file flags
-v23.proxy=
  object name of proxy service to use to export services across network
  boundaries
-v23.proxy.limit=0
  max number of proxies to connect to when the policy is to connect to all
  proxies; 0 implies all proxies
-v23.proxy.policy=
  policy for choosing from a set of available proxy instances
-v23.tcp.address=
  address to listen on
-v23.tcp.protocol=
  protocol to listen with
-v23.virtualized.advertise-private-addresses=
  if set the process will also advertise its private addresses
-v23.virtualized.disallow-native-fallback=false
  if set, a failure to detect the requested virtualization provider will result
  in an error, otherwise, native mode is used
-v23.virtualized.dns.public-name=
  if set the process will use the supplied dns name (and port) without
  resolution for its entry in the mounttable
-v23.virtualized.docker=
  set if the process is running in a docker container and needs to configure
  itself differently therein
-v23.virtualized.provider=
  the name of the virtualization/cloud provider hosting this process if the
  process needs to configure itself differently therein
-v23.virtualized.tcp.public-address=
  if set the process will use this address (resolving via dns if appropriate)
  for its entry in the mounttable
-v23.virtualized.tcp.public-protocol=
  if set the process will use this protocol for its entry in the mounttable
-v23.vtrace.cache-size=1024
  The number of vtrace traces to store in memory
-v23.vtrace.collect-regexp=
  Spans and annotations that match this regular expression will trigger trace
  collection
-v23.vtrace.dump-on-shutdown=true
  If true, dump all stored traces on runtime shutdown
-v23.vtrace.enable-aws-xray=false
  Enable the use of AWS x-ray integration with vtrace
-v23.vtrace.root-span-name=
  Set the name of the root vtrace span created by the runtime at startup
-v23.vtrace.sample-rate=0
  Rate (from 0.0 to 1.0) to sample vtrace traces
-v23.vtrace.v=0
  The verbosity level of the log messages to be captured in traces
-vmodule=
  comma-separated list of globpattern=N settings for filename-filtered logging
  (without the .go suffix).  E.g. foo/bar/baz.go is matched by patterns baz or
  *az or b* but not by bar/baz or baz.go or az or b.*
-vpath=
  comma-separated list of regexppattern=N settings for file pathname-filtered
  logging (without the .go suffix).  E.g. foo/bar/baz.go is matched by patterns
  foo/bar/baz or fo.*az or oo/ba or b.z but not by foo/bar/baz.go or fo*az

Stress stress - Run stress test ¶

Run stress test ¶

Usage:

stress stress [flags] <server> ...

<server> ... A list of servers to connect to.

The stress stress flags are:

-duration=1m0s
  duration of the test to run
-format=text
  Stats output format; either text or json
-max-chunk-count=1000
  maximum number of chunks to send per streaming RPC
-max-payload-size=10000
  maximum size of payload in bytes
-workers=1
  number of test workers to run

Stress stats - Print out stress stats of servers ¶

Print out stress stats of servers ¶

Usage:

stress stats [flags] <server> ...

<server> ... A list of servers to connect to.

The stress stats flags are:

-format=text
  Stats output format; either text or json

Stress load - Run load test ¶

Run load test ¶

Usage:

stress load [flags] <server> ...

<server> ... A list of servers to connect to.

The stress load flags are:

-cpu=0
  number of cpu cores to use; if zero, use the number of servers to test
-duration=1m0s
  duration of the test to run
-format=text
  Stats output format; either text or json
-payload-size=1000
  size of payload in bytes

Stress stop - Stop servers ¶

Stop servers ¶

Usage:

stress stop [flags] <server> ...

<server> ... A list of servers to stop.

Stress help - Display help for commands or topics ¶

Help with no args displays the usage of the parent command.

Help with args displays the usage of the specified sub-command or help topic.

"help ..." recursively displays help for all commands and topics.

Usage:

stress help [flags] [command/topic ...]

[command/topic ...] optionally identifies a specific sub-command or help topic.

The stress help flags are:

-style=compact
  The formatting style for help output:
     compact   - Good for compact cmdline output.
     full      - Good for cmdline output, shows all global flags.
     godoc     - Good for godoc processing.
     shortonly - Only output short description.
  Override the default by setting the CMDLINE_STYLE environment variable.
-width=<terminal width>
  Format output to this target width in runes, or unlimited if width < 0.
  Defaults to the terminal width if available.  Override the default by setting
  the CMDLINE_WIDTH environment variable.
