Analyse Your WordPress Website Stats in Power BI

WordPress is one of the most popular open-source website making tools which is vastly used by many bloggers including myself. WordPress developers provide tons of custom plugins to fulfil different needs. But not all of the plugins are well designed and secured.  One of the most interesting pieces of information anyone who owns a website/blog needs is their website statistics. In this post, I explain how to analyse your WordPress website stats in Power BI. Before I start, I want to point out that there is a WordPress stat already available in WordPress Admin Dashboard which provides very informative information about your blog like Total Views, Today Views, Best Ever Views and so forth. You can also install the WordPress app on your mobile device to easily access your website stats. But, the stats WordPress gives me in not enough. I want more. I need a more detailed analysis on

  • Current Month vs. Last Month
  • Current Year Vs. Last Year
  • Most Popular Day of Week
  • Most Popular Month of Year
  • Top 10 Posts

and so on.

As non of the above analysis are available in the normal stats , I decided to build my own version of “WordPress Website Stats Analysis in Power BI”. This gives me the flexibility of creating as much analysis as I need , and… it is so much fun.

If you own a WordPress blog or any other sort of websites or if you’re just curious to learn how to use a website API in Power BI, then this post is for you.

I managed to create a Power BI Desktop template that you can download and use it for free. You’re welcome to modify it based on your needs. You can find the download link at the button of the page.

How It Works

To be able to analyse your WordPress stats in Power BI you need to own a WordPress blog or website. Then a WordPress API key is assigned to your account. The key was included in your WordPress Welcome Email. You can use that API key in Power BI Desktop to create your customised reports and analyse your blog/website stats then you can publish the model into Power BI Service that is accessible anytime anywhere. You can also create your own dashboard in Power BI Service.  Moreover, you can setup Schedule Refresh for the dataset to refresh your dashboards and reports automatically.

Requirements

You’ll need to

  • own a WordPress blog/website and have the API assigned to your account
  • install the Jetpack plugin in your blog/website as WordPress stats is no longer maintained and you should not use it. Instead, you can install the Jetpack plugin
  • have Power BI Desktop installed on your machine (Download it from here, it’s free!)
  • have a Power BI account (Don’t have an account? Signup for it here, it’s free too!)

SSAS Tabular Model Documenter with Power BI without DMVs

SSAS Tabular Documenter with Power BITechnology is growing fast and we are enjoying it. We reshape our daily created data in a form that satisfies our needs. One of the technologies which is used more commonly these days is SQL Server Tabular Models, SSAS Tabular in short. Lots of industries decide to go with SSAS Tabular in their new projects and some defined new projects to slowly switch their existing SSAS Multidimensional to SSAS Tabular. I know, there is a big debate around SSAS Multidimensional vs. SSAS Tabular. But my aim is to prevent going through that sort of discussion. As the title implies, this post is about documentation that I believe is one of the most important parts of every project which is also sacrificed the most. In this post I explain how to document your SSAS Tabular model in Power BI Desktop and Excel. I know, there are some products you can find in the internet that can generate documentation in various formats like Word, PDF, HTML and so on. But, If you’re looking for a free and somehow more intuitive way of documenting your SSAS Tabular Models with Power BI then this article is for you.  Through this article, we create a documentation tool with Power BI. I call it SSAS Tabular Model Documenter. In this method we don’t use DMVs at all. For those who are not familiar with DMVs I shortly explain what DMVs are, if you’re already familiar with DMVs you can jump this section.

You can download a copy of SSAS Tabular Model Documenter in Power BI template format (pbit) at the end of this post. It is a Christmas present for you.

What are DMVs?

Dynamic Management Views, DMVs in short, are queries that retrieve metadata information about an instance of SQL Server Analysis Services. DMVs work on both SSAS Multidimensional and SSAS Tabular server modes. DMVs can be used to monitor server operations and health. The DMV query structure is very similar to T-SQL, therefore you use “SELECT” statement followed by “$System” which is an XMLA schema rowset. The DMV queries look like below:

SELECT * FROM $System.<schemaRowset>

So you can open SQL Server Management Studio, connect to an instance of SSAS (Tabular model for the sake of this post) and run the following query to get lots of information about tables in your Tabular model:

select * from $SYSTEM.TMSCHEMA_TABLES

Running DMVs in SSMSRead more about DMVs here.

Note:This method only works with SSAS Tabular 2016 and above.

Document SSAS Tabular without DMVs

In SSAS Tabular 2016 and above there is a tiny metadata database that can be loaded in Power BI Desktop or Excel to document the corresponding SSAS Tabular model. The database is a SQLite database. In the previous post I explained how to visualise SQLite data in Power BI. The requirements for this post are the same as the previous post, so I encourage you to check it out. Therefore, I just explain how to find the metadata file and how to build a model in Power BI Desktop. I also explain how to do the same in Excel for those of you who would like to add some annotations or comments to the outcomes.

Exporting Power BI Data to SQL Server

Exporting Power BI Data to SQL Server

Update 2021 March:

You can now export the data directly from Power BI Desktop using our free external tool, Power BI Exporter. Read more here.

Update 2019 April:

If you want to export the data model from either Power BI Desktop or Power BI Service to CSV or SQL Server check this out.

In the previous blog posts, I explained how to export Power BI data to Excel and CSV here and here. As promised in this post I explain how to export data from Power BI Desktop to SQL Server.

Hans Peter Pfister has already explained how to export data from Power BI Desktop to SQL Server using R scripts. Although Hans has done a brilliant job, it might be a bit hard to make it work if you don’t have any R experience and you don’t even know how to install and call R libraries. That’s so true about me, I’m NOT an R guy, but, who knows, maybe I will be. Smile 

But, what if you don’t want to go with R? If you are more involved with BI than analytics, then using R might not really be your cup of tea. Luckily, there is another way to export your Power BI data to SQL Server which is more BI friendly. You can export Power BI data to SQL Server using SSIS (SQL Server Integration Services). So if you are familiar with SSIS, then it might be your preferred choice.

With respect to Hans, in this post, I explain his method of exporting data from Power BI Desktop to SQL Server more in detail so that anyone who is not that familiar with R can make it work. I also explain how to export data from Power BI Desktop to SQL Server using SSIS. If there is any other methods you’re aware of please let me know in the comment section below.

Exporting Data from Power BI Desktop to SQL Server with R

As stated before, Hans has already explained this method here. So I don’t explain exactly what he did, but, I use his method to export data from the existing Power BI Desktop model to SQL Server and I explain it step-by-step.

Requirements

To make this method work you need to:

  • The latest version of Power BI Desktop, you can download it from here
  • Have access to an instance of SQL Server, either on your own machine or on a server in your local network to export the data to
  • Either install R for Windows, you can download it from here OR using an existing R-Server OR install SQL Server 2016 R Services
  • Install RODBC library for R, you can download the library from here

Note: I haven’t installed R Studio and nothing went wrong.

Installing RODBC Library for R and SQL Server R Services

As mentioned earlier, you can install R OR SQL Server R Services OR R-Server, but, as I haven’t tried R-Server myself I just explain how to install RODBC in R and SQL Server R Services.

You have to download the library from the link provided above, then extract the contents of the zip file which contains an “RODBC” folder. Then all you really need to do is to copy the “RODBC” to the “library” folder that exists in either R or SQL Server 2016 folders in your “Program Files” folder.

Library folder in R

Library folder in SQL Server 2016

How Does It Work?

Open an existing Power BI Desktop model that you’re willing to export its data to a SQL Server table and follow the steps below: (I use the “Internet Sales” model created on top of AdventureWorksDW. You can download my Power BI Desktop model at the end of this post.)

Exporting Data from Power BI Desktop to Excel and CSV – Part 2: Importing Power BI Data Directly to Excel

AAEAAQAAAAAAAAz4AAAAJGQ5ZTk4ZGUxLTI4YjQtNDc4ZC05NTQ4LWRjNDk3OTBlYTE5OQ

Update 2021 March:

You can now export the data direct from Power BI Desktop using my tool, Power BI Exporter. Read more here.

Update 2019 April:

If you’re interested in exporting the data model from either Power BI Desktop or Power BI Service to CSV or SQL Server check this out. The method explained here is only applicable for Power BI Premium or Embedded capacities with XMLA endpoints connectivity.

In my previous post I explained how to copy and paste data from Power BI Desktop into Excel or CSV. I also explained how easy you can export Power BI Desktop data to CSV using DAX Studio. As I promised, in this post I show you how to import Power BI Desktop data to Excel directly. In this method you don’t need to use any third-party software and the performance is much better than the previous methods.

Note: The method I explain in this post is tested in Excel 2016 only. But, it should work for Excel 2013.

Importing Power BI Desktop Directly to Excel

In one of my previous posts I explained how to connect to a Power BI Desktop from Excel. To import Power BI Desktop data to Excel we have to do the same thing. I explain the way to connect to a Power BI Desktop model directly from Excel, then I show you how to use this method to import Power BI Desktop data.

Finding Power BI Desktop local port number from Power BI Desktop temp directory

We can find Power BI Desktop local port number in number of ways explained here. So in this post I don’t go through all methods.

Whenever we run Power BI Desktop, it opens a random port number. The port number is independent of the model so it doesn’t really matter if  we haven’t connected to any data sources or even if we haven’t open any saved Power BI Desktop (*.PBIX) files. That port number is stored in a text file named “msmdsrv.port.txt”. So the only thing we need is to do is to browse the temp directory of Power BI Desktop and open the “msmdsrv.port.txt” text file. You can find Power BI Desktop temp folder here:

%LocalAppData%\Microsoft\Power BI Desktop\AnalysisServicesWorkspaces

There should be an “AnalysisServicesWorkspaceXXX” folder which XXX is a random number. Open that folder then open “Data” and Find “msmdsrv.port.txt”. Open the file to see Power BI Desktop local port number.
