Test classes
^^^^^^^^^^^^
Tools are configured via key-value attributes in test definition. For all networking tools Shaker offers unified parameters, that are translated
automatically.
iperf_graph, iperf:
~~~~~~~~~~~~~~~~~~~
* ``time`` - time in seconds to transmit for, defaults to `60`
* ``udp`` - use UDP instead of TCP, defaults to `TCP`
* ``interval`` - seconds between periodic bandwidth reports, defaults to `1 s`
* ``bandwidth`` - for UDP, bandwidth to send at in bits/sec, defaults to `1 Mbit/s`
* ``threads`` - number of parallel client threads to run
flent:
~~~~~~
* ``time`` - time in seconds to transmit for, defaults to `60`
* ``interval`` - seconds between periodic bandwidth reports, defaults to `1`
* ``method`` - which flent scenario to use, see https://github.com/tohojo/flent/tree/master/flent/tests for the whole list, defaults to `tcp_download`
netperf:
~~~~~~~~
* ``time`` - time in seconds to transmit for, defaults to `60`
* ``method`` - one of built-in test names, see http://linux.die.net/man/1/netperf for the whole list, defaults to `TCP_STREAM`
shell:
~~~~~~
* ``program`` - run single program
* ``script`` - run bash script
