[PATCH-next v3 00/21] CPU Utilization measurement and Perf refactoring
by olichtne＠redhat.com 16 Nov '18

16 Nov '18

From: Ondrej Lichtner <olichtne(a)redhat.com> Hi, this should be the final version of the patchset, v3 changes include: * improved sample parsing in lnst/Tests/CPUStatMonitor.py * removed whitespace error in patch 20 * added patch 21 that changes the lnst.Controller.Job kill API method, it will now check that the job is not finished before attempting an rpc call Thanks, Ondrej Previous message: Hi all, this is a second version of this patchset, v2 changes include: * the Namespace.run method reuses other methods instead of duplicating code * CPUStatMonitor comment explains the interval parameter * CPUStatMonitor bugfix for signal handling * fixed typo in IperfFlowMeasurement unit for cpu utilization * move and reimplementation of the TRex measurement class to fit into the whole redesign of the lnst.RecipeCommon.Perf package * updates to the OvSDPDKPVPRecipe: * stability improvements * refactoring to use the redesigned lnst.RecipeCommon.Perf package Thanks, -Ondrej Previous message: Hi all, the core of this patchset is refactorization of the PerfTestAndEvaluate recipe template into the lnst.RecipeCommon.Perf package implementing a template for generic performance measurement tests, moving the current MeasurementTools (Iperf and TRex) to fit this new model and adding CPUUtilization measurements. All of this is then incorporated into the BaseEnrtRecipe which is currently the main user of the Perf recipe template. There's also a couple of minor bug fixes and updates to the generic LNST API based on the experience of using them wrt. the main changes of this patchset. !!!!!!!! Some of these feel more like Proposals at this point though and I'm not sure if they're good ideas. This is mostly related to the prepare_job method of the Namespace class. It should definitely be considered and thought about before fully accepting it. !!!!!!!! Additional note: this patchset breaks the ENRT/OvS_DPDK_PvP.py due to the reorganization of the PerfRecipe. I wanted to send the patchset ASAP so that it can get some reviews. I'll work on updating the OvS_DPDK_PvP recipe while those reviews are coming in. And I won't merge this patchset without the additional fixes for Ovs_DPDK_PvP... Thanks, -Ondrej Ondrej Lichtner (21): lnst.Common.Utils: change std_deviation calculation lnst.Tests.Iperf: set target bitrate to 0 lnst.Common.Parameters: add ListParam lnst.Tests.Iperf: fix parallel parameter lnst.Tests.Iperf: add runtime_estimate method lnst.Tests.Iperf: cleanup imports lnst.Controller.Job: change wait default timeout lnst.Controller.RecipeResults: add data_level attribute lnst.Controller.RunSummaryFormatter: fix header format lnst.Controller.Namespace: add prepare_job method for delayed start lnst.Controller.Job: expose the what attribute add lnst.Tests.CPUStatMonitor lnst.RecipeCommon.{Perf, PerfResult}: refactoring add lnst.RecipeCommon.Perf.Measurements package lnst.Controller.RecipeResults: rename desc to description lnst.Controller.RunSummaryFormatter: improve multiline result descriptions RecipeCommon.Perf.Measurements: move NetworkFlowTest lnst.Tests.TestPMD: add pmd_coremask parameter Recipes.ENRT.OvS_DPDK_PvP: stability improvements refactoring of OvS_DPDK_PvP recipe and related classes lnst.Controller.Job: kill method checks if job is finished lnst/Common/Parameters.py | 18 ++ lnst/Common/Utils.py | 8 +- lnst/Controller/Job.py | 26 ++- lnst/Controller/Namespace.py | 32 +-- lnst/Controller/Recipe.py | 6 +- lnst/Controller/RecipeResults.py | 41 +++- lnst/Controller/RunSummaryFormatter.py | 10 +- lnst/RecipeCommon/IperfMeasurementTool.py | 83 ------- lnst/RecipeCommon/Perf.py | 120 ---------- .../Perf/Measurements/BaseCPUMeasurement.py | 109 +++++++++ .../Perf/Measurements/BaseFlowMeasurement.py | 220 ++++++++++++++++++ .../Perf/Measurements/BaseMeasurement.py | 29 +++ .../Perf/Measurements/IperfFlowMeasurement.py | 134 +++++++++++ .../Perf/Measurements/MeasurementError.py | 4 + .../Perf/Measurements/StatCPUMeasurement.py | 87 +++++++ .../Perf/Measurements/TRexFlowMeasurement.py | 149 ++++++++++++ .../Perf/Measurements/__init__.py | 4 + lnst/RecipeCommon/Perf/Recipe.py | 73 ++++++ .../{PerfResult.py => Perf/Results.py} | 65 +++--- lnst/RecipeCommon/Perf/__init__.py | 0 lnst/RecipeCommon/TRexMeasurementTool.py | 87 ------- lnst/Recipes/ENRT/BaseEnrtRecipe.py | 45 ++-- lnst/Recipes/ENRT/OvS_DPDK_PvP.py | 58 +++-- lnst/Tests/CPUStatMonitor.py | 115 +++++++++ lnst/Tests/Iperf.py | 14 +- lnst/Tests/TestPMD.py | 5 +- 26 files changed, 1124 insertions(+), 418 deletions(-) delete mode 100644 lnst/RecipeCommon/IperfMeasurementTool.py delete mode 100644 lnst/RecipeCommon/Perf.py create mode 100644 lnst/RecipeCommon/Perf/Measurements/BaseCPUMeasurement.py create mode 100644 lnst/RecipeCommon/Perf/Measurements/BaseFlowMeasurement.py create mode 100644 lnst/RecipeCommon/Perf/Measurements/BaseMeasurement.py create mode 100644 lnst/RecipeCommon/Perf/Measurements/IperfFlowMeasurement.py create mode 100644 lnst/RecipeCommon/Perf/Measurements/MeasurementError.py create mode 100644 lnst/RecipeCommon/Perf/Measurements/StatCPUMeasurement.py create mode 100644 lnst/RecipeCommon/Perf/Measurements/TRexFlowMeasurement.py create mode 100644 lnst/RecipeCommon/Perf/Measurements/__init__.py create mode 100644 lnst/RecipeCommon/Perf/Recipe.py rename lnst/RecipeCommon/{PerfResult.py => Perf/Results.py} (72%) create mode 100644 lnst/RecipeCommon/Perf/__init__.py delete mode 100644 lnst/RecipeCommon/TRexMeasurementTool.py create mode 100644 lnst/Tests/CPUStatMonitor.py -- 2.19.1
