From d7fd300e9a9bd480ad9f1500494021c42ec6ecee Mon Sep 17 00:00:00 2001 From: Hans Feldt Date: Fri, 26 Jun 2015 11:53:21 +0200 Subject: Add support to list and show runners & scenarios Example usage and output: $ yardstick runner list +------------------------------------------------------------------------------+ | Type | Description +------------------------------------------------------------------------------+ | Duration | Run a scenario for a certain amount of time | Arithmetic | Run a scenario arithmetically stepping an input value | Constant | Run a scenario a certain number of times +------------------------------------------------------------------------------+ $ yardstick runner show Duration Run a scenario for a certain amount of time If the scenario ends before the time has elapsed, it will be started again. Parameters duration - amount of time the scenario will be run for type: int unit: seconds default: 1 sec interval - time to wait between each scenario invocation type: int unit: seconds default: 1 sec $ yardstick scenario list +------------------------------------------------------------------------------+ | Type | Description +------------------------------------------------------------------------------+ | Iperf3 | Execute iperf3 between two hosts | Pktgen | Execute pktgen between two hosts | Ping | Execute ping between two hosts +------------------------------------------------------------------------------+ $ yardstick scenario show Iperf3 Execute iperf3 between two hosts By default TCP is used but UDP can also be configured. For more info see http://software.es.net/iperf Parameters bytes - number of bytes to transmit only valid with a non duration runner, mutually exclusive with blockcount type: int unit: bytes default: 56 udp - use UDP rather than TCP type: bool unit: na default: false nodelay - set TCP no delay, disabling Nagle's Algorithm type: bool unit: na default: false blockcount - number of blocks (packets) to transmit, only valid with a non duration runner, mutually exclusive with bytes type: int unit: bytes default: -
