Measure Killer

ein externes Tool für Microsoft Power BI

logo 2048.png

Aufräumen des Power BI Tenants

Measure Killer kann einen Power BI Tenant bzw. die Datasets aufräumen und optimieren. Dies kann die Refreshdauer reduzieren und so zu weniger Last auf der Premium Kapazität führen.

Measure Killer liest nur die Metadaten eines Dataset, nie die eigentlichen Daten. Da wir uns über XMLA verbinden, muss das Dataset nicht downgeloadet werden.

Analyse des Power BI Tenants

Der 5. Modus von Measure Killer "Tenant analysis" gibt einen Überblick über den gesamten Power BI Tenant. Als Beispiel können wir zeigen, wo Custom Visuals genutzt werden oder was in Personal Workspaces gebaut wurde. 

Löschen unbenutzter Measures

Measure Killer kann selbständig unbenutzte Measures löschen. Dies kann zur Bereinigung des Modells und der KPIs beitragen.

Löschen unbenutzter Spalten

Measure Killer generiert einen voll funktionsfähigen M-Code, der dann in den "Erweiterten Editor" der bereits bestehenden Query eingefügt werden kann. Kalkulierte Spalten können automatisch im Tool genau wie Measures entfernt werden.

Analyse eines Berichts

Für jeden Bericht wird ein detailliertes Excel oder json File erstellt, hier kann man einsehen, wo ein Artefakt verwendet wird. Dies kann in: Berechnungen, Visuals, Filter, Conditional Formatting, Joins in Power Query oder anderen Teilen eines Power BI Berichts wie z.B. Relationships sein. Diese Files können auch sehr gut als Dokumentation des Berichts oder Modells dienen.


Was wird vom Measure Killer erkannt?

  • Visuals - inklusive Filter welche auf das Visual, die Seite oder den Bericht angewendet werden

  • Artefakte die nur in Custom Visuals benutzt werden (siehe compatibility matrix weiter unten)

  • Jegliche Art von Measures oder Beziehungen

  • Spalten die ausschließlich in Power Query z.B. joins, appends, references genutzt werden

  • Calculated columns

  • Calculated tables

  • Conditional Formatting (bedingte Formatierungen)

Was geht nicht?

  • Wenn man ganze Berichte kopiert und dann nur diverse Änderungen macht, kann dies zu falschen Ergebnissen führen.

  • DAX Ausdrücke die nur auf Tabellen verweisen und keinerlei Referenzen auf Measures oder Spalten haben, werden nicht beachtet. (zB COUNTROWS)

  • Standardtitel und -untertitel (von Power BI vorgeschlagen/erstellt) werden nicht erkannt. Sobald der User diesen Titel abändert wird er erkannt.

  • Restriktive "sensitivity labels" können Fehler produzieren.

  • Spalten und Measures die nur im "neuen Mobile View" verwendet werden, sind aktuell nicht unterstützt - wir arbeiten daran.

  • Mehrmaliges entfernen und "restoren" von Measures oder Calculated Columns in einer Session kann zum Absturz führen (Version 2.0).

Measure Killer Security Information and Documentation
Version 2.0.0

This document outlines the security details and data handling practices of Measure Killer.

Data Handling and Privacy Assurance

Measure Killer is meticulously designed with user privacy and data security as paramount concerns. It is important for users to understand the scope and way that Measure Killer interacts with Power BI.

Metadata-Only Interaction

Measure Killer only interacts and utilizes metadata from Power BI Desktop or the Power BI Service. At no point does Measure Killer read, store, or process actual data contained within Power BI reports or models. This strict limitation to metadata ensures that sensitive data remains confidential and secure.

What is considered Metadata?

Metadata is considered the following (examples):
•    Names or artifacts (report, semantic models, workspaces, users/email addresses)
•    DAX and M expressions including comments
•    Names of measures, tables, calculated columns, calculated tables, calculation groups, field parameters etc.
•    Uncompressed size of columns
•    All definitions (e.g. name of reports, pages, visuals, visual titles, visual size and other metadata)

Local Processing of Metadata

All processing and analysis of metadata conducted by Measure Killer is performed locally on the user's machine through the installed client software. This approach ensures that the operations on metadata do not involve or require any external processing or storage facilities. By doing so, Measure Killer upholds a high standard of data protection and minimizes potential security risks. There is no database that is hosted, managed, or used to process any kind of information, everything is done on the user’s machine and not transmitted anywhere besides when using XMLA or REST API calls with Microsoft directly.

XMLA Endpoint Connection

To retrieve metadata from semantic models in the Power BI Service, XMLA endpoints are used. The authentication happens via the entered Microsoft account (see adomd client for more specifics on this).

API Calls to Microsoft for Metadata Acquisition

The only other external interaction Measure Killer undertakes involves REST API calls to Microsoft’s Power BI Service for the acquisition of metadata. These API calls are made in compliance with all relevant security protocols. Authentication happens via browser interaction (OAUTH2). Once metadata has been acquired, all subsequent analyses and operations are carried out locally. See the list at the bottom of this document for a list of REST API calls done.

Online / Offline Modes

Measure Killer is designed to be able to operate both online and offline:
•    In the offline modes, Measure Killer connects to the local instance of Analysis Services to retrieve the metadata it needs (Modes 1 and 2). In these modes the only time there is an interaction with the internet is upon launch to verify valid licensing (see License Verification below for details)
•    Online modes (Modes 3, 4 and 5) are triggered when an active internet connection is detected and when the user has a valid license. In these modes there are external connections happening (only REST API calls and XMLA connections to Microsoft as outlined above).

License Verification and Datetime Check 

•    Measure Killer uses API calls to acquire the current date and time: GET or, as a fallback, GET to ensure the license has not expired.

Version Check and User Notification

•    To inform users about available updates, Measure Killer queries GET to compare the installed version against the most recent version available the website.
•    There is one additional GET request to extract text and write it in the main UI window from this URL GET
API Endpoints and Security Measures
•    Secure requests (HTTPS) are made to Power BI API endpoints, ensuring data in transit is encrypted.
•    Access tokens are securely passed in request headers, with responses parsed as JSON for internal processing.

List of REST API Calls

•   GET{id}/datasets
•    GET{id}/reports
•    GET{id}/users
•    GET{}/reports/{}/datasources
•    GET{}/reports/{}/Export 
•    GET
•    GET
•    GET
•    GET
•    POST
•    POST{}/users
•    DELETE{}/users/{}

•    GET{}/artifactAccess?artifactTypes=”Workspaces”



There are two different versions. An "admin" version and a "non-admin" or portable version. In order to be able to install the admin version, the user must have administrator rights in the system. But basically the two versions work exactly the same. The only disadvantage of the "non-admin" version is that Measure Killer will not be automatically added to the "External Tools" in Power BI Desktop. Measure Killer in the Microsoft store is the "admin" version.

The documentation will soon be updated to show Measure Killer 2.0
