Presentation and Analytics Layer
================================

Overview
--------

The presentation and analytics layer (PAL) is the fourth layer of CSIT
hierarchy. The model of presentation and analytics layer consists of four
sub-layers, bottom up:

 - sL1 - Data - input data to be processed:

   - Static content - .rst text files, .svg static figures, and other files
     stored in the CSIT git repository.
   - Data to process - .xml files generated by Jenkins jobs executing tests,
     stored as robot results files (output.xml).
   - Specification - .yaml file with the models of report elements (tables,
     plots, layout, ...) generated by this tool. There is also the configuration
     of the tool and the specification of input data (jobs and builds).

 - sL2 - Data processing

   - The data are read from the specified input files (.xml) and stored as
     multi-indexed `pandas.Series <https://pandas.pydata.org/pandas-docs/stable/
     generated/pandas.Series.html>`_.
   - This layer provides also interface to input data and filtering of the input
     data.

 - sL3 - Data presentation - This layer generates the elements specified in the
   specification file:

   - Tables: .csv files linked to static .rst files.
   - Plots: .html files generated using plot.ly linked to static .rst files.

 - sL4 - Report generation - Sphinx generates required formats and versions:

   - formats: html, pdf
   - versions: minimal, full (TODO: define the names and scope of versions)

Data
----

Report Specification
````````````````````

The report specification file defines which data is used and which outputs are
generated. It is human readable and structured. It is easy to add / remove /
change items. The specification includes:

 - Specification of the environment.
 - Configuration of debug mode (optional).
 - Specification of input data (jobs, builds, files, ...).
 - Specification of the output.
 - What and how is generated:
   - What: plots, tables.
   - How: specification of all properties and parameters.
 - .yaml format.

Structure of the specification file
'''''''''''''''''''''''''''''''''''

The specification file is organized as a list of dictionaries distinguished by
the type:

::

    -
      type: "environment"
    -
      type: "configuration"
    -
      type: "debug"
    -
      type: "static"
    -
      type: "input"
    -
      type: "output"
    -
      type: "table"
    -
      type: "plot"
    -
      type: "file"

Each type represents a section. The sections "environment", "debug", "static",
"input" and "output" are listed only once in the specification; "table", "file"
and "plot" can be there multiple times.

Sections "debug", "table", "file" and "plot" are optional.

Table(s), files(s) and plot(s) are referred as "elements" in this text. It is
possible to define and implement other elements if needed.


Section: Environment
''''''''''''''''''''

This section has the following parts:

 - type: "environment" - says that this is the section "environment".
 - configuration - configuration of the PAL.
 - paths - paths used by the PAL.
 - urls - urls pointing to the data sources.
 - make-dirs - a list of the directories to be created by the PAL while
   preparing the environment.
 - remove-dirs - a list of the directories to be removed while cleaning the
   environment.
 - build-dirs - a list of the directories where the results are stored.

The structure of the section "Environment" is as follows (example):

::

    -
      type: "environment"
      configuration:
        # Debug mode:
        # - Skip:
        #   - Download of input data files

will be automatically changed to

::

    DIR[WORKING,DATA]: "_tmp/data"

Data to process
```````````````

The PAL processes tests results and other information produced by Jenkins jobs.
The data are now stored as robot results in Jenkins (TODO: store the data in
nexus) either as .zip and / or .xml files.


Data processing
---------------

As the first step, the data are downloaded and stored locally (typically on a
Jenkins slave). If .zip files are used, the given .xml files are extracted for
further processing.

Parsing of the .xml files is performed by a class derived from
"robot.api.ResultVisitor", only necessary methods are overridden. All and only
necessary data is extracted from .xml file and stored in a structured form.

The parsed data are stored as the multi-indexed pandas.Series data type. Its
structure is as follows:

::

    <job name>
      <build>
        <metadata>
        <suites>
        <tests>

"job name", "build", "metadata", "suites", "tests" are indexes to access the
data. For example:

::

    data =

    job 1 name:
      build 1:
        metadata: metadata
        suites: suites
        tests: tests
      ...
      build N:
        metadata: metadata
        suites: suites
        tests: tests
    ...
    job M name:
      build 1:
        metadata: metadata
        suites: suites
        tests: tests
      ...
      build N:
        metadata: metadata
        suites: suites
        tests: tests

Using indexes data["job 1 name"]["build 1"]["tests"] (e.g.:
data["csit-vpp-perf-1704-all"]["17"]["tests"]) we get a list of all tests with
all tests data.

Data will not be accessible directly using indexes, but using getters and
filters.

**Structure of metadata:**

::

    "metadata": {
        "version": "VPP version",

Data filtering
``````````````

The first step when generating an element is getting the data needed to
construct the element. The data are filtered from the processed input data.

The data filtering is based on:

 - job name(s).
 - build number(s).
 - tag(s).
 - required data - only this data is included in the output.

WARNING: The filtering is based on tags, so be careful with tagging.

For example, the element which specification includes:

::

    data:
      csit-vpp-perf-1707-all:
      - 9
      - 10
      - 13
      - 14
      - 15
      - 16
      - 17
      - 18
      - 19
      - 21
    filter:
      - "'64B' and 'BASE' and 'NDRDISC' and '1T1C' and ('L2BDMACSTAT' or 'L2BDMACLRN' or 'L2XCFWD') and not 'VHOST'"

will be constructed using data from the job "csit-vpp-perf-1707-all", for all
listed builds and the tests with the list of tags matching the filter
conditions.

The output data structure for filtered test data is:

::

    - job 1
      - build 1
        - test 1
          - parameter 1
          - parameter 2
          ...
          - parameter n
        ...
        - test n
        ...
      ...
      - build n
    ...
    - job n


Data analytics

Data analytics part implements:

 - methods to compute statistical data from the filtered input data.
 - trending.

                                1_core_throughput

Multi-core throughput speedup ratios are plotted in grouped bar graphs
for throughput tests with 64B/78B frame size, with number of cores on
X-axis and speedup ratio on Y-axis.

For better comparison multiple test results' data sets are plotted per
each graph:

    - graph type: grouped bars;
    - graph X-axis: (testcase index, number of cores);
    - graph Y-axis: speedup factor.

Subset of existing performance tests is covered by TSA graphs.

Comparison of results from two sets of the same test executions
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

This algorithm enables comparison of results coming from two sets of the
same test executions. It is used to quantify performance changes across
all tests after test environment changes e.g. Operating System
upgrades/patches, Hardware changes.

It is assumed that each set of test executions includes multiple runs
of the same tests, 10 or more, to verify test results repeatibility and
to yield statistically meaningful results data.

Comparison results are presented in a table with a specified number of
the best and the worst relative changes between the two sets. Following table
columns are defined:

    - name of the test;
    - throughput mean values of the reference set;
    - throughput standard deviation  of the reference set;
    - throughput mean values of the set to compare;
    - throughput standard deviation  of the set to compare;
    - relative change of the mean values.

**The model**

The model specifies:

    - type: "table" - means this section defines a table.
    - title: Title of the table.
    - algorithm: Algorithm which is used to generate the table. The other
      parameters in this section must provide all information needed by the used
      algorithm.
    - output-file-ext: Extension of the output file.
    - output-file: File which the table will be written to.
    - reference - the builds which are used as the reference for comparison.
    - compare - the builds which are compared to the reference.
    - data: Specify the sources, jobs and builds, providing data for generating
      the table.
    - filter: Filter based on tags applied on the input data, if "template" is
      used, filtering is based on the template.
    - parameters: Only these parameters will be put to the output data
      structure.
    - nr-of-tests-shown: Number of the best and the worst tests presented in the
      table. Use 0 (zero) to present all tests.

Advanced data analytics
```````````````````````

In the future advanced data analytics (ADA) will be added to analyze the
telemetry data collected from SUT telemetry sources and correlate it to
performance test results.

:TODO:

    - describe the concept of ADA.
    - add specification.


Data presentation
-----------------

Generates the plots and tables according to the report models per
specification file. The elements are generated using algorithms and data
specified in their models.


Tables
``````

 - tables are generated by algorithms implemented in PAL, the model includes the
   algorithm and all necessary information.
 - output format: csv
 - generated tables are stored in specified directories and linked to .rst
   files.


Plots
`````

 - `plot.ly <https://plot.ly/>`_ is currently used to generate plots, the model
   includes the type of plot and all the necessary information to render it.
 - output format: html.
 - generated plots are stored in specified directories and linked to .rst files.


Report generation
-----------------

Report is generated using Sphinx and Read_the_Docs template. PAL generates html
and pdf formats. It is possible to define the content of the report by
specifying the version (TODO: define the names and content of versions).


The process
```````````

1. Read the specification.
2. Read the input data.
3. Process the input data.
4. For element (plot, table, file) defined in specification:

   a. Get the data needed to construct the element using a filter.
   b. Generate the element.
   c. Store the element.

5. Generate the report.
6. Store the report (Nexus).

The process is model driven. The elements' models (tables, plots, files
and report itself) are defined in the specification file. Script reads
the elements' models from specification file and generates the elements.

It is easy to add elements to be generated in the report. If a new type
of an element is required, only a new algorithm needs to be implemented
and integrated.

How to add an element
`````````````````````

Element can be added by adding it's model to the specification file. If
the element is to be generated by an existing algorithm, only it's
parameters must be set.

If a brand new type of element needs to be added, also the algorithm
must be implemented. Element generation algorithms are implemented in
the files with names starting with "generator" prefix. The name of the
function implementing the algorithm and the name of algorithm in the
specification file have to be the same.
