QDC for QVDs marketplace dashboard

Key Performance Indicators (KPIs)

Data KPIs are a key component of the marketplace dashboard. KPIs measure QVD entities on business and health objectives like Size, Operational effectiveness, and Popularity.

KPI calculation is performed as a post-process so does not impact the success or failure of the load or dataflow execution.

KPI Display

KPI colors provide a quick gauge of how an entity scores on the following thresholds.

KPI colors






Good or Great. Meets business objective.



Risky or Ok. Needs attention/ is not performing optimally.



Below acceptable threshold or not performing relative to other entities. Note: This may not be a meaningful score if the business value of the data source is not reflected by the KPI . For example, in the case of popularity, an entity may get a low popularity score when the components driving the score (such as number of tags or frequency of publish and or prepare jobs) are not relevant or valuable measures for that entity.

Blue (QVD only)


Blue is used to indicate Size for QVDs; this metric does not indicate relative performance (good/bad) but simply a percentage size of the current QVD relative to the largest known QVD currently in the system.

KPI Scoring for QVDs

QVD KPI Scoring: Operation, Quality, Performance KPIs and Component Detail








Computes the difference between now and the last load and compares that to the typical update frequency. This metric will be N/A until QDC sees the first refresh coming from Qlik Sense.


Last_Load_Date_Time=Last time the QVD was loaded on Qlik Sense

First_Load_Date_Time=Time the QVD is synced on Qlik Sense upon QVD ingestion

Typical Period (typical interval between updates)=(Last_Load_Date_Time - First_Load_Date_Time)/Number_of_Loads

Latest Period=Now - Last_Load_Date_Time

Number of Loads=Number of times the QVD was loaded on Qlik Sense since first QDC ingest

If Number_of_Loads=1 THEN RECENCY is N/A

If Latest_Period <= Typical_Period THEN Recency = 1 (100%)

If Latest_Period > Typical_Period THEN Recency =.5

If (Latest_Period - Typical_Period) / Typical_Period<=0 THEN Recency=0

Note: All variables in these calculations refer to the QVD generation on the Qlik Sense side, NOT the loads of QVD metadata into QDC.

Operational Total



Size Volume


Relative size of the QVD in memory/storage units (file size on disk)

(QVD Size - Smallest QVD Size) / (Largest QVD Size - Smallest QVD Size)

If all QVDs are the same size (unlikely) =1


Size Records


Relative size of the QVD in number of records

(# records in QVD - smallest # records across all QVDs) / (largest # records across all QVDs - smallest # records across all QVDs)

If all QVDs have the same number of records (unlikely)=1

Size Total   1000% (Replaces Quality metric applied to Non-QVD entities)


Number of Tags


Count of tags compared to average (includes both tags imported from Qlik and tags created in Qlik Data Catalyst)

Average Tags=Total # of tags across all QVDs / # of QVDs

0.5 + ((# tags for the QVD - Average_Tags) / Average_Tags) *0.5)

If above is greater than 1 = 1

If Average_Tags is 0 = 0


Number of Comments


Count of comments (Qlik Data Catalyst Comments, previously known as "blog") compared to average

Average Comments=Total # of comments across all QVDs / # of QVDs

0.5 + ((# comments for the QVD - Average_Comments) / Average_Comments) *0.5)

If above is greater than 1 = 1

If Average_Comments is 0 = 0


Number of Publish Jobs


Count of Publish jobs executed including QVD compared to average

Average Publish Jobs= Total # of executed publish jobs across all QVDs / # of QVDs

0.5 + ((# executed Publish jobs using the QVD - Average_Publish_Jobs) / Average_Publish_Jobs) *0.5)

If above is greater than 1 = 1

If Average_Publish_Jobs is 0 = 0

Popularity Total


Behavior and configuration of KPI metrics

If any or all metric computations fail, the data load can still complete successfully and the reason for the failure is logged. Therefore, to refresh scores, reload the entity.

Admins: KPI computation can be turned off for an entity or source by enabling the KPIs at entity and source levels or setting global core-env property: enable.kpi=true (default)

To configure a defined time window in which to capture loads, the following property can be set globally in of measure= days):metric.computation.window=60 (default)

Note: Setting this value to a negative number (e.g.,"-1" ) will use all historical loads to compute metrics.

To configure the time period in days for which the historical custom entity metrics are retained, the following property can be set globally in (unit of measure=days): metric.retention.window=60(default)

Note: Setting this value to a negative number (e.g.,"-1”) will delete all historical metrics keeping only the current (latest) ones.

Entity Details

Add to Cart to include QVDs in a dataset or Create Dataset with selected QVDs, or Publish to Qlik Sense or Qlik Sense Advanced .

Add to Cart

Publish to Qlik Sense and Publish to Qlik Sense Advanced

Users are able to choose one or more QVDs in either catalog (by selecting cart icons on QVD tiles of interest) or discover (selecting/multi-selecting the row or rows then Add to Cart). Either method will place the QVDs in the cart from where users can Take Action to choose a destination for the selected QVD. This section will focus on the publish options.

Create or Add to an Existing Dataset: Datasets are logical collections of sources or entities. It is an organizational framework only, there are no particular rules dictating how users group the objects they have access to. Choose to Create and name a new set or Add the selected QVDs to an already existing dataset.

Publish to Qlik Sense: Exports QVDs to a preconfigured instance of Qlik Sense Enterprise. This option creates a new application for each published entity in Insight Advisor, the entry point for exploring your data and creating visualizations.

Publish to Qlik Sense Advanced: Exports QVDs to user's choice of location in Qlik Sense Enterprise: Insight Advisor (default), Data Load Editor, or Data Load Manager. Developers building Qlik Sense applications select to publish directly to Data Load Editor or Data Manager by setting a default target page in User Preferences (Profile>User Profile and Preferences>Publish to Qlik Sense Starting View) with the ability to over-ride the default setting after selecting Publish to Qlik Sense Advanced from (My Cart) action dropdown.

Developers building Qlik Sense applications can create a new application with a published entity (as before) or pick an existing Qlik Sense app from the list of existing user apps and add published entities to it.

Set Default Choice of Starting Target View in Profile

Over-ride Publish to Qlik Sense Default Starting View and optionally choose Qlik Sense application to add QVD entity to

To access a Lineage Report for the Entity, select the Lineage icon.

QVD Lineage Report


Data lineage in Qlik Data Catalyst displays an entity's origins and exports or transforms over its lifecycle. Qlik Data Catalyst catalog supports a lineage graph display that visually details bidirectional events: downstream (descendants) and upstream (ancestor) dependencies. Users are able to control the Direction and Depth in the UI graph through display level dropdowns in the upper right of the graph. Lineage can also be accessed for individual entities through the More dropdown in the discover entity grid.

Double-click on an individual node to collapse or expand the nodes underneath (downstream of) that node.

Qlik Data Catalyst: Lineage Graph Displaying Upstream Lineage for Qlik Sense QVDs with JSON display

Lineage Graph Legend (Only relevant icons are described.)
Icon Description

Process: Blue dots represent processes that stage entities into different object types (ex. from External Source to External Entity to Internal Entity).

Available process types are:

M: Technical Metadata load

L: Data load

Qlik App: Lineage of the QVD file coming from the Qlik Installation and stored in the QVD XML header, representing how the QVD file was created. The name of the Qlik app is either the file extracted from either Windows or Linux filepath, the App Session id, or UUID (Universally Unique Identifier)—depending on how lineage information is extracted from QVD XML CreatorDoc tag.

This icon is also used to represent a Qlik App publish target.

Source: Source in this context represents the external database object as named in Qlik Data Catalyst. Entities (tables)/ fields (columns)  are selected for inclusion.

External Entity: The entity is an external representation in Qlik Data Catalyst of how the table is stored in the originating RDBMS source format. The entity is displayed with original source metadata related to ingest in Qlik Data Catalyst source module.

Internal Entity: The entity has been internalized + metadata environment is established. Once data is loaded, it is stored inreceiving directory. Internal entity metadata can be found in Qlik Data Catalyst discover module.

QVD Internal: QlikView Data file imported from Qlik Sense. QVDs are entities that behave like other source types though KPIs measures Size rather than performance

QVD External: QlikView Data file external representation as stored in Qlik Sense server database

Other: External process outside of Qlik Data Catalyst that doesn't fall under any of the other object categories
