1 Presentation and Analytics Layer
2 ================================
7 The presentation and analytics layer (PAL) is the fourth layer of CSIT
8 hierarchy. The model of presentation and analytics layer consists of four
11 - sL1 - Data - input data to be processed:
13 - Static content - .rst text files, .svg static figures, and other files
14 stored in the CSIT git repository.
15 - Data to process - .xml files generated by Jenkins jobs executing tests,
16 stored as robot results files (output.xml).
17 - Specification - .yaml file with the models of report elements (tables,
18 plots, layout, ...) generated by this tool. There is also the configuration
19 of the tool and the specification of input data (jobs and builds).
21 - sL2 - Data processing
23 - The data are read from the specified input files (.xml) and stored as
24 multi-indexed `pandas.Series <https://pandas.pydata.org/pandas-docs/stable/
25 generated/pandas.Series.html>`_.
26 - This layer provides also interface to input data and filtering of the input
29 - sL3 - Data presentation - This layer generates the elements specified in the
32 - Tables: .csv files linked to static .rst files.
33 - Plots: .html files generated using plot.ly linked to static .rst files.
35 - sL4 - Report generation - Sphinx generates required formats and versions:
38 - versions: minimal, full (TODO: define the names and scope of versions)

62 The report specification file defines which data is used and which outputs are
63 generated. It is human readable and structured. It is easy to add / remove /
64 change items. The specification includes:
66 - Specification of the environment.
67 - Configuration of debug mode (optional).
68 - Specification of input data (jobs, builds, files, ...).
69 - Specification of the output.
70 - What and how is generated:
71 - What: plots, tables.
72 - How: specification of all properties and parameters.
75 Structure of the specification file
76 '''''''''''''''''''''''''''''''''''
78 The specification file is organized as a list of dictionaries distinguished by
102 Each type represents a section. The sections "environment", "debug", "static",
103 "input" and "output" are listed only once in the specification; "table", "file"
104 and "plot" can be there multiple times.
106 Sections "debug", "table", "file" and "plot" are optional.
108 Table(s), files(s) and plot(s) are referred as "elements" in this text. It is
109 possible to define and implement other elements if needed.
115 This section has the following parts:
117 - type: "environment" - says that this is the section "environment".
118 - configuration - configuration of the PAL.
119 - paths - paths used by the PAL.
120 - urls - urls pointing to the data sources.
121 - make-dirs - a list of the directories to be created by the PAL while
122 preparing the environment.
123 - remove-dirs - a list of the directories to be removed while cleaning the
125 - build-dirs - a list of the directories where the results are stored.
127 The structure of the section "Environment" is as follows (example):
136 # - Download of input data files
138 # - Read data from given zip / xml files
139 # - Set the configuration as it is done in normal mode

905 The PAL processes tests results and other information produced by Jenkins jobs.
906 The data are now stored as robot results in Jenkins (TODO: store the data in
907 nexus) either as .zip and / or .xml files.
913 As the first step, the data are downloaded and stored locally (typically on a
914 Jenkins slave). If .zip files are used, the given .xml files are extracted for
917 Parsing of the .xml files is performed by a class derived from
918 "robot.api.ResultVisitor", only necessary methods are overridden. All and only
919 necessary data is extracted from .xml file and stored in a structured form.
921 The parsed data are stored as the multi-indexed pandas.Series data type. Its
922 structure is as follows:
932 "job name", "build", "metadata", "suites", "tests" are indexes to access the
961 Using indexes data["job 1 name"]["build 1"]["tests"] (e.g.:
962 data["csit-vpp-perf-1704-all"]["17"]["tests"]) we get a list of all tests with

1084 The data filtering is based on:
1089 - required data - only this data is included in the output.
1091 WARNING: The filtering is based on tags, so be careful with tagging.
1093 For example, the element which specification includes:
1098 csit-vpp-perf-1707-all:
1110 - "'64B' and 'BASE' and 'NDRDISC' and '1T1C' and ('L2BDMACSTAT' or 'L2BDMACLRN' or 'L2XCFWD') and not 'VHOST'"
1112 will be constructed using data from the job "csit-vpp-perf-1707-all", for all
1113 listed builds and the tests with the list of tags matching the filter
1116 The output data structure for filtered test data is:

1144 Throughput Speedup Analysis - Multi-Core with Multi-Threading
1145 '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
1147 Throughput Speedup Analysis (TSA) calculates throughput speedup ratios
1148 for tested 1-, 2- and 4-core multi-threaded VPP configurations using the
1154 N_core_throughput_speedup = -----------------
1157 Multi-core throughput speedup ratios are plotted in grouped bar graphs
1158 for throughput tests with 64B/78B frame size, with number of cores on
1159 X-axis and speedup ratio on Y-axis.
1161 For better comparison multiple test results' data sets are plotted per
1164 - graph type: grouped bars;
1165 - graph X-axis: (testcase index, number of cores);
1166 - graph Y-axis: speedup factor.
1168 Subset of existing performance tests is covered by TSA graphs.

1193 Comparison of results from two sets of the same test executions
1194 '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
1196 This algorithm enables comparison of results coming from two sets of the
1197 same test executions. It is used to quantify performance changes across
1198 all tests after test environment changes e.g. Operating System
1199 upgrades/patches, Hardware changes.
1201 It is assumed that each set of test executions includes multiple runs
1202 of the same tests, 10 or more, to verify test results repeatibility and
1203 to yield statistically meaningful results data.
1205 Comparison results are presented in a table with a specified number of
1206 the best and the worst relative changes between the two sets. Following table
1207 columns are defined:
1210 - throughput mean values of the reference set;
1211 - throughput standard deviation of the reference set;
1212 - throughput mean values of the set to compare;
1213 - throughput standard deviation of the set to compare;
1214 - relative change of the mean values.
1218 The model specifies:
1220 - type: "table" - means this section defines a table.
1221 - title: Title of the table.
1222 - algorithm: Algorithm which is used to generate the table. The other
1223 parameters in this section must provide all information needed by the used
1225 - output-file-ext: Extension of the output file.
1226 - output-file: File which the table will be written to.
1227 - reference - the builds which are used as the reference for comparison.
1228 - compare - the builds which are compared to the reference.
1229 - data: Specify the sources, jobs and builds, providing data for generating
1231 - filter: Filter based on tags applied on the input data, if "template" is
1232 used, filtering is based on the template.
1233 - parameters: Only these parameters will be put to the output data
1235 - nr-of-tests-shown: Number of the best and the worst tests presented in the
1236 table. Use 0 (zero) to present all tests.

1270 Advanced data analytics
1271 ```````````````````````
1273 In the future advanced data analytics (ADA) will be added to analyze the
1274 telemetry data collected from SUT telemetry sources and correlate it to
1275 performance test results.
1279 - describe the concept of ADA.
1280 - add specification.
1286 Generates the plots and tables according to the report models per
1287 specification file. The elements are generated using algorithms and data
1288 specified in their models.
1294 - tables are generated by algorithms implemented in PAL, the model includes the
1295 algorithm and all necessary information.
1296 - output format: csv
1297 - generated tables are stored in specified directories and linked to .rst
1304 - `plot.ly <https://plot.ly/>`_ is currently used to generate plots, the model
1305 includes the type of plot and all the necessary information to render it.
1306 - output format: html.
1307 - generated plots are stored in specified directories and linked to .rst files.
1313 Report is generated using Sphinx and Read_the_Docs template. PAL generates html
1314 and pdf formats. It is possible to define the content of the report by
1315 specifying the version (TODO: define the names and content of versions).
1321 1. Read the specification.
1322 2. Read the input data.
1323 3. Process the input data.
1324 4. For element (plot, table, file) defined in specification:
1326 a. Get the data needed to construct the element using a filter.
1327 b. Generate the element.
1328 c. Store the element.
1330 5. Generate the report.
1331 6. Store the report (Nexus).
1333 The process is model driven. The elements' models (tables, plots, files
1334 and report itself) are defined in the specification file. Script reads
1335 the elements' models from specification file and generates the elements.
1337 It is easy to add elements to be generated in the report. If a new type
1338 of an element is required, only a new algorithm needs to be implemented

1476 How to add an element
1477 `````````````````````
1479 Element can be added by adding it's model to the specification file. If
1480 the element is to be generated by an existing algorithm, only it's
1481 parameters must be set.
1483 If a brand new type of element needs to be added, also the algorithm
1484 must be implemented. Element generation algorithms are implemented in
1485 the files with names starting with "generator" prefix. The name of the
1486 function implementing the algorithm and the name of algorithm in the
1487 specification file have to be the same.
