We all know and love Power BI, because of it’s power and ease of use, there’s a good reason why it’s number 1 in the Gartner Quadrant. But how to we avoid ‘Power BI Hell’, the new version of our old nemesis ‘Excel Hell’?
How do we keep track of which data sources are being used by which datasets and reports? How to we perform an impact assessment of updating/changing a dataset? What happens if someone deletes a Power BI report? There has been no easy solution to this, until now.
Step forward a new SaaS tool, Power BI Sentinel
Sentinel is a new Software as a Service (i.e. hosted in the cloud) tool which sits alongside your PowerBI.com account, helping you manage things better. Core features include:
- Data Lineage documentation – visibility of which reports are using which datasets, and which data sources. Plus showing which downstream datasets and reports will be impacted by deleting or changing a data source or dataset
- Automated Backups – backing up your PBIX files directly to your own Azure storage. Allowing you to roll back, recover deleted files, and see what the report/data looked like in the past for debug/investigation
- Automated Dataset Documentation – Generate online or PDF documentation of your Power BI datasets, the model, tables, DAX measures, calculated columns, etc.
- Report Change Tracking – If someone’s broken a report by adding/removing a filter, changing a visual, etc. the change tracking will show you what has changed, and when, allowing you to roll back to the correct version prior to the change
The diagram above shows a sample Data Lineage diagram of a Power BI Dataset, showing which data sources (databases, files, websites, etc.) are used by the dataset, and which reports then consume this dataset.
Scenario 1: Power BI Governance, Compliance, GDPR
You have a data source, lets say an Oracle database, containing sensitive customer details (PII). When auditing your organisation’s usage of this data, which of your 600 Power BI reports do you need to review to assess whether that PII data is exposed or not, and to who?
The Power BI Data Lineage explorer allows you to select a datasource, and immediately see which datasets and reports consume data from that source, including those hidden away in users’ personal ‘My Workspace’ folders. Straight away refining the list of sensitive reports to a handful.
Scenario 2: Power BI Disaster Recovery
Your well behaved development teams obviously follow good DevOps practice for all their development work (hopefully!), but Power BI is a self service tool, allowing your business users to create their own reports. And you’re almost certainly not going to get business users using source control and good testing practices on their reports.
Self service is a very powerful feature which significantly enhances the benefit of Power BI to your organisation. But if ‘Mary from Finance’ creates a report that becomes business critical, if that report gets corrupted, broken, deleted or changed, there is no recovery or rollback to the previous version of that report.
Power BI Sentinel not only gives you visibility of whether these critical reports are hidden in personal workspaces, but also performs regular automated backups of the reports, allowing you to recover and roll back if required.
Power BI is a very powerful tool, but with great power comes great responsibility.
Power BI Sentinel is a great way of providing transparency over your Power BI tenant, and protecting you if anything should ever go wrong.

I think it’s about time for a good old rant. Nothing to do with Business Intelligence, but…
Anyone out there who uses Sky Anytime (and I believe the BBC iPlayer) will have probably noticed that they use a nasty peer-to-peer file sharing application called Kontiki, which they install automatically without giving you any control over. My problem is that I have a good 8Mb download speed but my upload is still a rather paltry 256K (I know, it’s almost embarrasing). I use Sky Anytime to download a film probably no more than once a month, the rest of the time Kontiki sits there on my PC hogging my precious upload bandwith. They don’t give you any control over restrict it or turning it off – hense my rant.
I’m happy to leave it running for a bit when it’s not causing a problem, but I want to easily be able to turn it off. So, the solution? Create a Kontiki-Killer batch file that disables it. When you next launch Sky Anytime it will automatically load again, but when you’re finished, you can run this batch file to kill the little blighter.
It kills the KHost.exe process, stops the KService service, sets the KService to start manually not automatically (so it will only start when you launch Sky Anytime), and removes KHost.exe from the startup options in the registry (Sky will add them back in when it is next launched).
I use this on my XP Pro SP2 box, I’ve not tried it on any other OS, so I can not accept any responsibility for any problems is may cause – use entirely at your own risk.
Copy this into a blank text file, and save it as KillKontiki.bat
