Summary: This page explains how to configure the CAST Application Analytics Dashboard tile interface

The CAST Application Analytics Dashboard has a "tile" or "panel" based interface that provides access to the data:

CAST AIP 8.3.x Documentation > HD - Tile management > tiles.jpg

These tiles have default presentation settings, but this can be modified and tailored to your requirements. For example:

Tile colours can be changed
Tile positions can be changed
Tile contents can be changed
Tile size can be changed
New tiles can be added

Editing your tiles presentation

The default tile presentation is defined in the following files:

File name

Usage

%CATALINA_HOME%\webapps\CAST-AAD\portal\resources\cmp.json

This file governs the display of tiles when your Measurement Service contains multiple Applications - i.e the Multi-application landing page.

%CATALINA_HOME%\webapps\CAST-AAD\portal\resources\app.json

This file governs the display of tiles for a single Application - i.e the Application landing page. This page is displayed in two situations:

When the Measurement Service contains information about only one Application
When you have drilled down from the Multi-application landing page into a single Application.

For more information about the Multi-application and Application landing pages, see CAST Application Analytics Dashboard - CAST AAD.

To modify the presentation, edit the .json file with a text editor (Notepad or other similar application). CAST recommends:

creating a copy of the default .json files that can be used as a replacement if an error occurs during editing
first changing existing parameters such as color and title and also moving Tiles around before you begin making large scale and more complex changes

Note that CAST provides "library" files containing examples of all the tiles that can be created and used in the CAST Application Analytics Dashboard. You can use these files as well as the examples in this documentation page to build your own tiles. These library tiles can be found along side the live cmp.json and app.json files:

%CATALINA_HOME%\webapps\CAST-AAD\portal\resources\cmp_tiles_library.json
%CATALINA_HOME%\webapps\CAST-AAD\portal\resources\app_tiles_library.json

Viewing the changes in your browser

There is no need to restart the application server or application itself if you edit and save the cmp.json or app.json files: changes are immediate on saving the file. However, you may find that the changes are not immediately visible in the CAST Application Analytics Dashboard. This is because the .json files are loaded into the browser's cache, therefore CAST recommends that you empty your browser cache to force the changes to become visible.

If you are using Google Chrome the following tip can be used to automatically empty the browser cache:

Tap F12 to open the Developer Tools window at the bottom of the page.
Click the Settings icon (a cog) to the right of the Developer Tools window
Tick the Disable cache (while DevTools is open) option and close the Settings window.
In this state, when you then tap F12 followed by F5 to refresh the page, the browser cache will be automatically emptied.

Changing the positions of tiles

Tiles are displayed in the CAST Application Analytics Dashboard in a left to right and top to bottom format within each "Area" (see below). In the .json file, Tiles are listed one after the other, therefore to move a Tile, you need to change its position in the .json file using copy/paste: the higher up the list within the "Area" you place the tile code, the higher up it will be displayed in the dashboard itself.

Structure of the .json

The .json file is divided into various different sections, each corresponding to an item, area or tile in the Application Analytics Dashboard:

Areas

There are three areas, each corresponding to the Overview, Evolution and Software Enhancement Function Points (since Previous Version) (app.json only) sections you can see by default:

CAST AIP 8.3.x Documentation > HD - Tile management > areas.jpg

These are represented in the .json file as follows:

"id": 1,
"title": "Overview",

and:

"id": 3,
"title": "Evolution",

and:

"id": 2,
"title": "Software Enhancement Function Points (since Previous Version)",

Tiles

Within each Area, various Tiles (or Panels) are defined, for example:

            {
                "id": 5,
                "plugin": "QualityIndicatorResults",
                "color": "yellow",
                "parameters": {
                    "title": "Robustness",
                    "qualityIndicator": {"id": "ROBUSTNESS", "format": "0.00"},
                    "details":{
                        "ranges":[1.6,2.8,3.0,3.4]
                    },
                    "widget": "gauge"
                }
            },

Available parameters in .json

Global parameters

Please see CAST-AAD - Dashboard wide configuration options in json for more information about the following parameters that can be defined in the cmp.json (and in the app.json) to provide dashboard wide parameterization (i.e, they are valid regardless of whether your dashboard contains one or multiple Applications):

    "title": "Application Analytics Dashboard",
    "language": "dev",
    "horizontalScroll": false,
    "confirmLogout": true,
	"persistNavigationFilters":true,
	"filtering":{
      "filterTags":false
    },
    "period": {
        "shift": true,
        "periods": [
            { "diff": 30, "units": "days" },
            { "diff": 3, "units": "months" },
            { "diff": 6, "units": "months" },
            { "diff": 12, "units": "months", "selected": true },
            { "diff": 2, "units": "years" },
            { "diff": 0, "units": "alltime" }
        ]
    }

Tile parameters

A tile or panel represents the equivalent of a "plugin". Each tile is composed of the following properties:

Parameter	Description
id	Represents the tile's unique id. This is a technical id used to identify the panels and MUST be unique throughout the .json file.
plugin	Represents the type of indicators to be displayed in the tile. The plugins that are available are listed below under Plugin parameters.
color	Optional parameter that describes the tile color theme to be used. A light grey color is used if none is defined. Colors are currently limited to: blue black dark grey orange green purple light grey yellow
size	Optional parameter provides the ability to expand tiles in size (large and small):
autoFit	Optional parameter that (when set to true - the default position) will truncate a plugin's title text if it is longer than the size of the tile (whether a large or small tile). Using this parameter may lead to visually less consistent dashboards. The default value is true, where the font size used for a plugin's title text will be reduced so that the title text fits the tile size. To deactivate the autoFit option, you need to specifically add the parameter to your plugin and set it to false.
parameters	This section contains plugin specific parameters. Please refer to each of the following plugin definitions under Plugin parameters for more information about this.

Technical Size Measures parameters

Only available in app.json.

Technical Size Measures govern the configurable display of Technical Size indicators (Number of Critical Violations, Number of Code Lines, Number of Files etc.) for the drill down page available at Application level for the Technical Size tile (click to enlarge):

CAST AIP 8.3.x Documentation > HD - Tile management > technicalsizemeasures.jpg

Each of these indicators can be configured via the app.json file under the TechnicalSizeMeasures section:

Parameter	Description
id	Represents the ID of the Technical Size indicator as defined in the CAST Assessment Model.
label	A text field used to display the name of the Technical Size indicator in the drill down page (click to enlarge):

for example:

"TechnicalSizeMeasures": {
    "values": [
      {
        "id": 67011,
        "label": "Number of Critical Violations"
      },
      {
        "id": 10151,
        "label": "Number of Lines of Code"
      },
      {
        "id": 10154,
        "label": "Number of Files"
      },
      {
        "id": 10155,
        "label": "Number of Classes"
      },
      {
        "id": 10156,
        "label": "Number of Programs"
      },
.....

Plugin parameters

A plugin also has various different parameters as follows:

Note that:

some plugins are named specifically for use in a specific .json file. In otherwords, a plugin will have two unique names, one for the cmp.json and one for the app.json. Plugins that function like this are documented as such below.
plugins that function in the cmp.json file may not necessarily function in the app.json file (and vice-versa)

Common plugin parameters

Parameter	Description
title	A title used to identify the tile.
mode	Determines how much detail will be presented in a tile. Not all tiles support the attribute. terse verbose
qualityIndicator or sizingMeasure	Represent the measurement data properties (typically the indicator identifier, some high level description and the value formatting). quality indicator ids include i.e. ARCHITECTURAL_DESIGN, CHANGEABILITY, DOCUMENTATION, LINES_OF_CODE, PERFORMANCE, PROGRAMMING_PRACTICE, ROBUSTNESS, SEI_MAINTAINABILITY, SECURITY, TQI, TRANSFERABILITY it is possible to use the ID of any CAST AIP metric in place of the worded indicator IDs listed above. For example the LINES_OF_CODE indicator can be replaced with 10151 (the equivalent ID). the format in which the value has to be displayed, it uses the the format defined in numeral.js (see http://numeraljs.com/ for available Numbers formats.
scope	Enables a specific filter to be added to a tile (and related detail) to focus on Applications assigned to a defined tag and related category. Both sub-parameters are mandatory: category the category name tag the tag name in the category The parameter is global to tile configuration but only applies to the following plugins: PortolioListing QualityIndicatorResults and QualityIndicatorEvolution SizingMeasureResults SizingMeasureEvolution BackgroundFactsResults BackgroundFactsEvolution CustomExpressions CustomExpressionsEvolution See Note about tags and categories as tile scopes in CAST Application Analytics Dashboard - CAST AAD.

PortfolioListing

This tile is only available for use in the cmp.json file - in other words at multi-app/portfolio level.

Without scope:

Note that:

ONLY five items will be shown in the tile itself, however, you can configure more than 5 items if you wish - the extra items will be displayed when you click the tile to drill down
Any items with a value of 0 in the tile itself will not be displayed when you click the tile to drill down

Example (for cmp.json)

            {
                "id": 1000,
                "plugin": "Notification",

                    ]
                }
            }

BackgroundFactsResults / BackgroundFactsResult

Note that:

when using this tile in the cmp.json file, please use BackgroundFactsResults
when using this tile in the app.json file, please use BackgroundFactsResult

CAST AIP 8.3.x Documentation > HD - Tile management > backgroundfactresults.jpg

A tile that enables you to display Background Facts that you have manually configured and uploaded during the snapshot generation. The tile can display information about one metric that you have defined in the uploaded Background Facts file.

backgroundFact: information about the indicator to display : its id, format and an optional description
- id refers to the Background Fact numerical ID as displayed in the Assessment Model in the CAST Management Studio (in recent versions, the IDs with a "metric_group" value of 6):

CAST AIP 8.3.x Documentation > HD - Tile management > backgroundfactresults_ID.jpg

- format is the format in which the value has to be displayed, it uses the the format defined in numeral.js (see http://numeraljs.com/ for available Numbers formats)
- description is whatever is required
url: the url field provides a simple means to link the drill down at detail level to some other web based information. Since the metrics comes from non-CAST sources, the external page containing information on the details of the metric, can be linked to here. If no url is provided, drill down cannot be achieved and a message will be displayed in tooltips on tile or charts whenever applicable:

CAST AIP 8.3.x Documentation > HD - Tile management > backgroundfactresults_URL.jpg

zoom: true or false to enable zooming in detail charts. Default value is true. The zoom feature works best when you have multiple Applications consolidated into your CAST Application Analytics Dashboard - in this situation it can be difficult to read the score details of each column (a column represents one Application). You can therefore use the zoom option to select (using the mouse) the Applications you want to zoom into.
aggregation: (sum or average), tile will aggregate the application background fact values using sum or average - default value is sum. For example: if you have two Applications visible in the CAST Application Analytics Dashboard and have configured a Background Fact (a Cost of 400 for example) for only one of the Applications, results will be displayed as follows:
- AVERAGE: A value of 200 will be displayed in the tile at Multi-application level (400 divided by 2) and in the tiles at Application level.
- SUM: A value of 400 will be displayed in the tile at Multi-application level and at Application level, 400 will be displayed for the Application for which the Background Fact has been uploaded and 0 for the Application for which no Background Fact has been uploaded.

Example (for cmp.json)

        {
            "id": 66002,
            "plugin": "BackgroundFactsResults",

                     }
                }

Example Background Facts configuration

In this example, there are two Applications present in the CAST Application Analytics Dashboard. Background Facts have been configured and uploaded (see Background Facts and Business Value Metric upload for more information) for one of the Applications as shown below. The tile has been designed to show information about the Cost (66002) metric (see example plugin for cmp.json).

BackgroundFactsEvolution

Note that this tile can be used at multi (cmp.json) and single (app.json) Application level.

CAST AIP 8.3.x Documentation > HD - Tile management > backgroundfactsevolution.jpg

A tile that enables you to display the evolution of Background Facts that you have manually configured and uploaded during the snapshot generation. The tile can display information about one metric that you have defined in the uploaded Background Facts file.

backgroundFact: see the BackgroundFactsResult/BackgroundFactsResults tile above for more info.
aggregation; see the BackgroundFactsResult/BackgroundFactsResults tile above for more info.
widget: provides the rendering type (number for number variation, line or spline for trend chart representation: line uses with straight lines whereas spline provides smooth transitions between points)
selectedApplicationCount defines the number of applications selected by default in the drill down at detail level page when the tile is defined at multi-application level (cmp.json).

Clicking the tile

When defined at multi-application level (cmp.json), clicking a tile will display the following Background Fact detail for the Applications in scope:

When defined at single application level (app.json), clicking a tile will by default display the evolution of TQI. If you need to view the details of the evolution of your Background Facts at single application level, you need to make some further configuration changes as follows:

Edit the following file with a text editor:

%CATALINA_HOME%\webapps\CAST-AAD\portal\resources\internal\app-navigation.json

Search for the "id": "evolution", section in the file and then add a new "group" containing the Background Facts you want to display in the drill down detail page at application level. For example, the following group contains all possible Background Facts:

{
"id": "backgroundFacts",
"description":"Background Facts",
"indicators": [
    {
    "description": "Effort",
    "id": "66001",
    "format":"0,000",
    "selected": true
    },
    {
    "description": "Cost",
    "id": "66002",
    "format":"0,000",
    "selected": false
    },
    {
    "description": "Enhancement Function Points",
    "id": "66003",
    "format":"0,000",
    "selected": false
    },
    {
    "description": "Delivery Feature Requests",
    "id": "66004",
    "format":"0,000",
    "selected": false
    },
    {
    "description": "Pending Feature Requests",
    "id": "66005",
    "format":"0,000",
    "selected": false
    },
    {
    "description": "Pending Fixes",
    "id": "66007",
    "format":"$0,000",
    "selected": false
    },
    {
    "description": "Business Value",
    "id": "66061",
    "format":"$0,000",
    "selected": false
    }
]
}

Save the file when you have added the Background Facts you require.
To view the changes, you may need to empty your browser cache as described at the beginning of this document. The screenshot below shows the evolution detail page for a BackgroundFactsEvolution tile at single application level with the list of Background Facts highlighted:

    3. textAlign: The text alignment for the label determines how the text is aligned against its anchor point. Possible values are "left", "center" and "right".
    4. verticalAlign: Vertical alignment of the label relative to the plot band. Can be one of "top", "middle" or "bottom". Defaults to top.
3. plotBands: An array of colored bands stretching across the plot area marking an interval on the axis:
  1. from: the start position of the plot band in axis units.
  2. to: the end position of the plot band in axis units.
  3. color: the color of the plot band.
  4. label: text labels for the plot bands
    1. align: horizontal alignment ("left", "center" or "right")
    2. text: The string text itself. A subset of HTML is supported.
    3. textAlign: The text alignment for the label determines how the text is aligned against its anchor point. Possible values are "left", "center" and "right".

CriticalQualityRulesRatios / CriticalQualityRuleRatio

Note that:

when using this tile in the cmp.json file, please use CriticalQualityRulesRatios
when using this tile in the app.json file, please use CriticalQualityRuleRatio

CAST AIP 8.3.x Documentation > HD - Tile management > CriticalQualityRulesRatios.jpg

This tile shows the top 5 critical rules at Application or multi-Application level, together with:

Checked column: the number of times the rule has been checked - i.e. the number of objects checked by the Quality Rule
Failed (%) or Failed (#) column: the percentage or number of checks that have failed - i.e. percentage or number of objects checked by the Quality Rule that violate the Quality Rule

Configuration:

type: Describe the type of notifications - set to topRules
count: the number of lines displayed. 5 is the optimized size for the height of the tile
order: the ordering of the Quality Rules represented in the tile. This can be descending or ascending, and is based on the number of failed checks
format: the format of the compliance value: it uses the the format defined in numeral.js (see http://numeraljs.com/ for available Numbers formats)
mode: two options are possible:
- “ratio”: a Failed (%) column will display a percentage of the checks that have failed - i.e. percentage of objects checked by the Quality Rule that violate the Quality Rule.
- “number”: a Failed (#) column will display the number of the checks that have failed - i.e. the number of objects checked by the Quality Rule that violate the Quality Rule.
loadLimit: Compared to other tiles, this tile tends to involve large amount of data when the application scope increases, hence can quickly prove to be performance inefficient; the loadLimit option defines a limit for the number of applications: when there are less Applications than the loadLimit value, then the contents of the tile will be loaded. When there are more Applications than the loadLimit value, then the contents of the tile will not be loaded and a message will state this.

sizingMeasure

Note that at multi Application level (i.e. configuration in the cmp.json file), the following are also available for use with the sizingMeasure item: AUTOMATED_IFPUG_FUNCTION_POINTS_ESTIMATION, UNADJUSTED_DATA_FUNCTION_POINTS, UNADJUSTED_TRANSACTIONAL_FUNCTION_POINTS, ADDED_FUNCTION_POINTS, ADDED_DATA_FUNCTION_POINTS, ADDED_TRANSACTIONAL_FUNCTION_POINTS, MODIFIED_FUNCTION_POINTS, MODIFIED_DATA_FUNCTION_POINTS, MODIFIED_TRANSACTIONAL_FUNCTION_POINTS, DELETED_FUNCTION_POINTS, DELETED_DATA_FUNCTION_POINTS, DELETED_TRANSACTIONAL_FUNCTION_POINTS, UNCHANGED_FUNCTION_POINTS, UNCHANGED_DATA_FUNCTION_POINTS, UNCHANGED_TRANSACTIONAL_FUNCTION_POINTS

Be extra careful with these metrics as they have values only if you have the EFP license key, and if all Applications do not have function points, the tile can exhibit display issues (squares can be very small in an empty space). The tile will only display Applications that have results for configured indicators.

CAST AIP 8.3.x Documentation > HD - Tile management > QualityIndicatorResults.jpg

qualityIndicator: information about the indicator to display : its id, format and an optional description
1. id is either: ARCHITECTURAL_DESIGN, CHANGEABILITY, DOCUMENTATION, PERFORMANCE, PROGRAMMING_PRACTICE, ROBUSTNESS, SEI_MAINTAINABILITY, SECURITY, TQI, TRANSFERABILITY
2. id can also be a numerical ID corresponding to any CAST AIP metric
3. format is the format in which the value has to be displayed, it uses the the format defined in numeral.js (see http://numeraljs.com/ for available Numbers formats)
4. technicalId is the ID of the Technical Criteria you want to display, for example "61003" would display "Programming Practices - OO Inheritance and Polymorphism" in the tile. Functions at Portfolio and Application level.
5. description is whatever is required
details provide parameters dedicated towards drill down page views
1. ranges: range used to separate indicator groups displayed in detail view. Default is [2,3] to produce : [indicator < 2, 2 <= indicator < 3, 3<= indicator]
2. colors: from hex code color to hex code color. from provides the grade 1 white to provide the grade 4 color values. Default values are #CE2029 for grade 1 and #28AC1B for grade 4. The choice of a gradient or plain colors can be made through the useGradient parameter. Default value is false.
widget provides graphical representations of the indicator (e.g. gauge or donut)
1. If widget is set to riskGauge, then the gauge will display color based on the indicator score with regard to riskGauge configuration (thresholds and colors). The tile color theme is restricted to grey-light and grey-dark when using this widget. Default color is grey-dark.
icon: boolean to display (true) an icon next to the tile title, false by default.
zoom: true or false to enable zooming in detail charts. Default value is true. The zoom feature works best when you have multiple Applications consolidated into your CAST Application Analytics Dashboard - in this situation it can be difficult to read the score details of each column (a column represents one Application). You can therefore use the zoom option to select (using the mouse) the Applications you want to zoom into.
riskGauge: can be set globally in the top level QualityIndicatorResults global configuration and can be overridden in the tile parameters. Parameters are used if the widget parameter is set to riskGauge
1. thresholds: define the thresholds used to qualify the score risk; default values are: [2, 3, 3.99] meaning high-risk:1 to 2, risk:2 to 3, low risk:3 to 3.99, and very low risk over
2. colors: define the colors accordingly to the thresholds (keep in mind that 3 thresholds means 4 areas, hence 4 colors)

Parameters are available panel per panel. Some general parameters can be set on the top most level of the json structure through the "QualityIndicatorResults" field. The parameters set there involve the details fields such as ranges, color or riskGauge.

1. id is either: TECHNICAL_DEBT, LINES_OF_CODE, NUMBER_OF_ARTIFACTS, NUMBER_OF_COMMENT_LINES, NUMBER_OF_DECISION_POINTS, NUMBER_OF_FILES, NUMBER_OF_FUNCTION_POINTS, NUMBER_OF_BACKFIRED_FUNCTION_POINTS and CRITICAL_VIOLATIONS
2. id can also be a numerical ID corresponding to any CAST AIP metric
3. description is whatever is required
4. format is the format in which the value has to be displayed, it uses the the format defined in numeral.js (see http://numeraljs.com/ for available Numbers formats)
5. widget provides the rendering type (number for number variation, line or spline for trend chart representation - line uses straight lines whereas spline provides smooth transitions between points)

zoom: true or false to enable zooming in detail charts. Default value is true. The zoom feature works best when you have multiple Applications consolidated into your CAST Application Analytics Dashboard - in this situation it can be difficult to read the score details of each column (a column represents one Application). You can therefore use the zoom option to select (using the mouse) the Applications you want to zoom into.

Example (for cmp.json)

            {
                "id": 12,
                "plugin": "SizingMeasureResults",
                "color": "orange",
                "parameters": {
                    "title": "Critical violations",
                    "mode":"terse",
                    "sizingMeasure": {"id": "CRITICAL_VIOLATIONS", "format": "0,000"}
                }
            },

Example (for app.json)

                {
                    "id": 102,

                        }
                    }
                },

ExternalLink

This tile (not available by default) provides the ability to define external URLs (e.g. to other data dashboards) in a tile:

CAST AIP 8.3.x Documentation > HD - Tile management > externallink.png

color: tile color
parameters:
- title the short message to display in tile
- url the hyperlink to follow

Example (for cmp.json and app.json)

{
    "id": 100,
    "plugin": "ExternalLink",
    "color": "red",
    "parameters": {
        "title": "Tackle your Technical Debt",
        "url":"http://www.castsoftware.com"
    }
},

Custom expression tiles

At portfolio (cmp.json) and application level (app.json), it is possible to define tiles with custom expressions. A custom expression is defined through a mathematical subset representation involving operations on criteria values (e.g. the ratio of number of lines of codes per critical violations or the count of applications with more than n files).

The tile can represent averaged values (excluding the application not having one of the values such as a background fact or some sizing measure, or those whose function calculation result is infinite) or a total value. For comparison, business criteria scores are average while sizing is usually a total on the portfolio.

Custom expression tiles can be defined for the current snapshot state (most recent snapshot for all applications at portfolio level or selected snapshots at application level), or via evolutions.

The mathematical formula available involve the following expression patterns:

Operators

Operator	Name	Syntax	Associativity	Example	Result
(, )	Parentheses	(x)	None	2 * (3 + 4)	14
,	Parameter separator	x, y	Left to right	max(2, 1, 5)	5
+	Add	x + y	Left to right	4 + 5	9
-	Subtract	x - y	Left to right	7 - 3	4
*	Multiply	x * y	Left to right	2 * 3	6
/	Divide	x / y	Left to right	6 / 2	3
%, mod	Modulus	x % y	Left to right	8 % 3	2
^	Power	x ^ y	Right to left	2 ^ 3	8
!	Factorial	y!	Left to right	5!	120
? :	Conditional expression	x ? y : z	Right to left	15 > 100 ? 1 : -1	-1

Functions

Function	Name	Syntax	Associativity	Example	Result
abs	Absolute	abs(x)	None	abs(-2)	2
round	Round	round(x,n)	None	round(3.142265,3)	3.142
sqrt	Square root	sqrt(x)	None	sqrt(4)	2
log	Logarithmic	log(x,base)	None	log(1024,2) log(1024)	10 3.01

Other classic patterns are available but may not be supported by the CAST Application Analytics Dashboard in terms of rendering (i.e. those returning non numerical values such as booleans).

CustomExpressionsEvolution

The custom expression tile enables operations on various multiple indicators in a single tile through snapshots. Lots of different operations can be performed on the tile, from scaling to combinations using mathematical formula (as listed above). As it could involve multiple results and extra operations to get the results, the CustomExpressionsEvolution tiles could hinder the performances of the dashboard at some point (depending on number of tiles, number of variables, number of snapshots).

Standard parameters

title please note that exceptionally, the title is used to identify different types of custom expression tiles, from result to evolution, portfolio to application level. if you want to avoid duplicates at application level detail, please make sure tiles with the same formula have the same title field.
description
format

Tile specific parameters

documentation a documentation information to explain about the custom indicator. The field value is a string (that can include html tags) that will be displayed on page details at portfolio level.
aggregator the aggregation type: "average" or "sum", default to average.
expression the mathematical operation to perform for each application (some examples: "sqrt((tqi-1)/3)", "tqi/loc", "log(x)*y^2", etc.)
variables each variable defined in the mathematical operation has to be defined for results to be caclulated. The variable name is defined through its key and have a type and an id. (some examples: "variables":{"tqi":{"type":"qualityIndicator", "id":"TQI"},"loc":{"type":"sizingMeasure", "id":"LINES_OF_CODE"},"effort":{"type":"backgroundFact", "id":"EFFORT"}}

Notes about the aggregator type "AvgSum"

When using this aggregator type, a new property "aggregator" can also be provided for each key under "variables" to specify the aggregation type as "sum" or "average" for each variable respectively. The default is set to "sum" when "AvgSum" is defined under "aggregator". For example the following lines under "variables" would take both factors produce a sum and then divide them. As such it is now possible to specify the addition of all the violations first, then add up all the function points, THEN do the division (the SUM(Violations) / SUM(Function points) ):
