PowerShell – Accessing Power BI Desktop Data Cube and more…

November 18, 2018

Recently I got interested in getting data out of a Power BI Data Model to push into an SQL database.

On my way I discovered a lot of interesting techniques and Tools for Power BI Desktop.

1. First of all you need to know that Power BI Desktop actually is a small Web Server running an SSAS Mini Cube.

2. Next you need to prepare PowerShell to access the PBI Cube.

Solution :

In order to start you first need to start PBI Desktop and open a PBIX file you created before.

Once started you need to find out on which Random Port is was started.

There are 4 way to get the job done.

1. Install Dax Studio which you need to have, no question about this !

    Even if you are not using it for getting the Random Port…

Look in the bottom right corner :


2. Command line tool NETSTAT

   Run NETSTAT –b command and look for Power BI


In this case it was Port 60520

3. Look for the msmdsrv.port.txt file.

Once PBI is started it will create some folders and files.

You can find those here :

%LocalAppData%\Microsoft\Power BI Desktop\AnalysisServicesWorkspaces\


If you have multiple PBIX files open you will see more Random created subfolders.

Go to the random created folder and next to the Data Subfolder.

Open the msmdsrv.port.txt file to get the Port number.


4. Using the Tabular Editor

But it needs some dependent MS AS AMO Libraries



Now that you know how to get access to the Web Server Port.

PowerShell 32 Bit

You can now test PowerShell connection to the Power BI Desktop you have open.

But you first need a Connection String to be used in PowerShell

FIRST USE the 32 Bit PowerShell if you are using a 32 Bit Office installation.

Later in this post I will explain how to get it running in a 64Bit PS even if you have a 32 Bit Office installed.

I suggest that you use EXCEL for this to copy and paste it Winking smile

Go to Data and choose From Analysis Services.


Follow these steps :





Copy it from here :


You can also get the Catalog GUID from the folder name where you could find the Port number.


Run this PowerShell Script, it uses a DMV Query to get hold of the PBI Cube Properties


$Port = "60520"
$Catalog = "cff5b9a8-2f87-416c-97fd-8eccd5962d51"

$Query = 'Select * from $SYSTEM.DISCOVER_PROPERTIES'

$connectionString = "Provider=MSOLAP;Integrated Security=SSPI;Persist Security Info=True;Data Source=localhost:$Port;Initial Catalog=$Catalog"
$connection = New-Object -TypeName System.Data.OleDb.OleDbConnection

$connection.ConnectionString = $connectionString
$command = $connection.CreateCommand()
$command.CommandText = $query
$adapter = New-Object -TypeName System.Data.OleDb.OleDbDataAdapter $command
$dataset = New-Object -TypeName System.Data.DataSet

$dataset.Tables[0] | Format-Table # export-csv $filename -notypeinformation


To list data from a Table use the EVALUATE command

$Query = 'EVALUATE Tickets'


PowerShell 64 Bit

If you are running a 32 Bit Office, you need to install the OLAP Drivers for 64 bit

(will be done when you install DAX Studio).


Or manually register the MSOLAP.DLL from the Power BI install folder.


Tools :

Power Pivot :

You can connect to a Power BI Desktop model using Power Pivot for example.



Dax Studio :

You can run commands directly against your Power BI Desktop.

Use DAX Commands


Or use a DMV Query to select the data from the PBI Meta Data or the Data Set.

// Select data using DMV queries


// Or select all DATA from the PBI Data Set using this command



For more info on DMV Queries see here

Windows Server 2016 – HP iLO PowerShell and more…

November 9, 2018



HPE Integrated Lights-Out (iLO),

HPE Onboard Administrator (OA) for HPE BladeSystem Enclosures and

System BIOS of HPE ProLiant servers, this set of PowerShell utilities



We will only use iLO at this moment, because this is the most valuable.

It is a proprietary embedded server management technology of HP.

iLO makes it possible to perform activities on an server from a remote location. Even if the server OS is not responding.


1. Download the PowerShell Module

See here at the moment we are at version 2.1



2. Load the PS Module

Check the version



import-module "C:\Program Files (x86)\Hewlett Packard Enterprise\PowerShell\Modules\HPEiLOCmdlets\HPEiLOCmdlets.psd1"

Get-Module -ListAvailable "HPEiLO*"



List the Cmdlets

Get-Command -Module "HPEiLOCmdlets"




Update the PS Module if needed



Search for iLO servers in your network using a range or subnet

$IPRange = Read-host " Enter the IP Range of HPOA ( "

Find-HPEiLO $IPRange


Now you are ready to run some cmdlets.


Let’s check the power of the server:

Get-HPEiLOServerPower -Connection $connection



Let’s check the Temperature Sensors

$Ret = Get-HPEiLOTemperature -Connection $connection

$Ret.Temperature | Out-GridView




3. iLO commandline Tools

The HP management utillity called hponcfg.exe is installed here.



iLO config Export Example :

Command :


hponcfg.exe /w c:\Temp\iloconfig.txt




You can use the is config file to make changes to your iLO configuration, like resetting your Password etc.


hponcfg /f your_script_name.txt

PowerBI – Using FreshDesk Web Services API

November 7, 2018

We started exploring the use of the FreshDesk cloud-based customer support platform.

Which is one of the modules of the FreshWorks Suite.

You can start off with a free subscription, which is good enough to start building you BI tool.


Once you are happy you can switch over to a paid subscription giving you extra features.


One of them is extensive reporting,

After exploring the Power BI integration. I found out that all of the third party solution provided did not work Sad smile

And one if the solutions required that you have a Power BI Pro licence…


So I ended up making my own Power BI Dashboard using the FreshDesk REST Web Services API.

See here for the API documentation : https://developers.freshdesk.com/api/

The Web Service API looks very straight forward and works with any REST compatible application.

Implementing this in Power BI, was challenging.

But as you can see here, you can do all you need in your Free Power BI Desktop too.

So this will save you some licenses money too Winking smile

You can start off with a free subscription, which is good enough to start building your BI Dashboards.



Shows that Power BI is the right marriage for the 2 platforms, O365 and FreshDesk Winking smile

In case you need to run this as offline data source or want to schedule reports.

You can use PowerShell to extract the data, and use this as a data source.

This will save you quite some money uplifting your subscription.


Example :

If you have 25 Agents and you need to schedule reports. Your subscription is $19 / user / month more expansive.

This is a burden of an additional $5,000 subscription cost.

Other paid service provider is FreshInsights / Radiare



If you run the Invoke-WebRequest command against your URI in Powershell.

Like this :

$Data = Invoke-WebRequest -uri $URL -Headers $Headers -Method GET -ContentType application/json 


You can see in the response header information the API Version and the remaining calls you have

In this case 2996 out of 3000 per hour !

This is a limit set by Freshdesk to reduce the maximum API calls per hour.

Steps to get started using Power BI using the Web Service API :

1. create a free trial subscription

2. Copy your Web Service API Key


3. Open Power BI and do a Get DATA Web Data



Paste in the web service URL for Tickets for example.

4. Connect to FreshDesk using the API Key and password


PS : To use the Power BI Service and Scheduled REFRESH,

        you need to use the Anonymous Authentication !

5. Next built your Queries and transformations to extract the data


6. Build your Visuals and Measures


Tips and Tricks

An EXTRA Bonus is that you can incorporate this in your SharePoint Online site.

No license needed see here on how to.


Schedule a Refresh using Power BI Service

Recently Microsoft changed the Power BI service policy.

Where you can’t schedule a refresh when using a public web service ?


But no worries there is a solution for this too Winking smile

Windows Server 2016 – Volsnap Error Event ID 27 & Event ID 153

November 7, 2018

Accidently I noticed some Disk Warnings Event ID 153. Together with a VSS error Volsnap Event ID 27.

All at the time we had scheduled a backup to run.


The message was :

The shadow copies of volume \\?\Volume{xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} were aborted during detection because a critical control file could not be opened.


First recommendation is to resize the VSS Storage Area.

Or even put the settings to No Limit


For more info see here : http://hyper-v-backup.backupchain.com/how-to-fix-volsnap-error-a-critical-control-file-could-not-be-opened/

At the link you can also download a small Free Utility called VSSDiag.


This can help you debug further issues.

PS : This is also linked to Event ID 3, see here for more info



Enjoy !
