Command line options
|
|
============================
|
|
|
|
Yandex.Tank has an obviously named executable ``yandex-tank``.
|
|
Here are available command line options:
|
|
|
|
:-h, --help:
|
|

|
|
|
|

|
|

:-i, --ignore-lock:
|
|

|
|
|
|
:-f, --fail-lock:
|
|

|
Options set in cmd line override those have been set in configuration files. Multiple times for multiple options.
|

|
|
|
|
|
|
Add an ammo file name as a nameless parameter, e.g.:
|
|
``yandex-tank ammo.txt`` or ``yandex-tank ammo.gz``
|
|
|
|
Advanced configuration
|
|
============================
|
|
|
|
Configuration files organized as standard INI files. Those are files
|
|
partitioned into named sections that contain 'name=value' records.
|
|
|
|
Example:
|
|
::
|
|
|
|
[phantom]
|
|
address=example.com:80
|
|
rps_schedule=const(100,60s)
|
|
|
|
[autostop]
|
|
autostop=instances(80%,10)
|
|
|
|
.. note::
|
|
A common rule: options with the
|
|
same name override those set before them (in the same file or not).
|
|
|
|
Default configuration files
|
|
--------------------------------
|
|
|
|
If no ``--no-rc`` option passed, Yandex.Tank reads all ``*.ini`` from
|
|
``/etc/yandex-tank`` directory, then a personal config file ``~/.yandex-tank``.
|
|
So you can easily put your favourite settings in ``~/.yandex-tank``
|
|
|
|
Example: ``tank.artifacts_base_dir``, ``phantom.cache_dir``, ``console.info_panel_width``
|
|
|
|
The ``DEFAULT`` section
|
|
--------------------------------
|
|
|
|
One can use a **magic** ``DEFAULT`` section, that contains global
|
|
options. Those options are in charge for every section:
|
|
|
|
::
|
|
|
|
[autostop]
|
|
autostop=time(1,10)
|
|
|
|
[console]
|
|
short_only=1
|
|
|
|
[aggregator]
|
|
time_periods=10 20 30 100
|
|
|
|
[meta]
|
|
job_name=ask
|
|
|
|
is an equivalent for:
|
|
|
|
::
|
|
|
|
[DEFAULT]
|
|
autostop=time(1,10)
|
|
short_only=1
|
|
time_periods=10 20 30 100
|
|
job_name=ask
|
|
|
|
.. note::
|
|
Don't use global options wich have same name in different sections.
|
|
|
|
|
|
Multiline options
|
|
--------------------------------
|
|
|
|
Use indent to show that a line is a continuation of a previous one:
|
|
|
|
::
|
|
|
|
[autostop]
|
|
autostop=time(1,10)
|
|
http(404,1%,5s)
|
|
net(xx,1,30)
|
|
|
|
.. note::
|
|
|
|
Ask Yandex.Tank developers to add multiline capability for options
|
|
where you need it!*
|
|
|
|
Referencing one option to another
|
|
-----------------------------------
|
|
|
|
``%(optname)s`` gives you ability to reference from option to another. It helps to reduce duplication.
|
|
|
|
Example:
|
|
|
|
::
|
|
|
|
[DEFAULT]
|
|
host=target12.load.net
|
|
|
|
[phantom]
|
|
address=%(host)s
|
|
port=8080
|
|
|
|
[monitoring]
|
|
default_target=%(host)s
|
|
|
|
[shellexec]
|
|
prepare=echo Target is %(host)s
|
|
|
|
Time units
|
|
--------------------------------
|
|
|
|
*Default* : milliseconds.
|
|
|
|
Example:
|
|
|
|
::
|
|
|
|
``30000 == 30s``
|
|
``time(30000,120)`` is an equivalent to ``time(30s,2m)``
|
|
|
|
Time units encoding is as following:

|
Abbreviation Meaning
|
|
============= =======
|
|
ms millisecons
|
|
s seconds
|
|
m minutes
|
|
h hours
|
|
============= =======
|
|
|
|
.. note::
|
|
You can also mix them: ``1h30m15s`` or ``2s15ms``.
|
|
|
|
Shell-options
|
|
---------------------
|
|
|
|
Option value with backquotes is evaluated in shell.
|
|
|
|
Example:
|
|
|
|
::
|
|
|
|
[meta]
|
|
job_name=`pwd`
|
|
|
|
Artifacts
|
|
================
|
|
|
|
As a result Yandex.Tank produces some files (logs, results, configs
|
|
etc). Those files are placed with care to the **artifact directory**. An
|
|
option for that is ``artifacts_base_dir`` in the ``tank`` section. It is
|
|
recommended to set it to a convenient place, for example,
|
|
``~/yandex-tank-artifacts``; it would be easier to manage the artifacts
|
|
there.
|
|
|
|
Sources
|
|
================
|
|
|
|
Yandex.Tank sources are `here <https://github.com/yandex-load/yandex-tank>`_.
