Skype for Business Rate My Call with Power BI Analysis


When you are running a Skype for Business Online environment, CQD allows you to gain insights into the quality of calls via metrics and absolute network measurements from calls meta data.

The context and the actual user experience is collected through the Rate My Call, the RMC data is not currently included in any existing monitoring report, but it has a separate monitoring report. Data is collected in SQL tables that can be accessed by running SQL queries (work on reports in progress).

While we are waiting for the Rate My call Reports from Microsoft there is a way to produce our customized reports by the tools available now from Power BI and in this post we will create these reports by Power BI and use the Cognitive Analysis from Azure to analyze the user sentiment.

 

This Report shows User Sentiment from RMC data and analyzed with Azure Cognitive services in Power BI

This Report shows the Percentage of Subnets (resolved from Tenant Building Data) where users had complained by rating.

*Since VPN subnet in CQD shows as 1 IP per subnet its impossible to group them as one Region, in this post we will reverse-resolve them based on the Building data we have, so VPN IPs shows in their respective subnet name.

Requirements:

1- RMC is enabled and Users are giving feedback

2- Dump from the RMC Database (Explained below)

3- Power BI Desktop and Active account

4 - * (Optional) A Microsoft Azure account. Start a free trial or sign in.

5-* (Optional) A access key for Text Analytics. Sign up, then get your key.

  • * Only required for the Text Analytics report you can still skip those and use the other reports.

The Reports that we are going to Produce are the following:

1- Reports on who rated the least Stars

2- Reports on who rated with most feed backs

3- Correlation between feedbacks, Stars and subnets.

4- you can be creative with any report from the data given from the RMC.

 

So lets begin with the RMC Data Dump, Thanks to Jason Shave who wrote this blog on how to extract the RMC data through his script (https://www.powershellgallery.com/packages/CxdCallData/1.1.6.1 )

This Script will dump all your RMC data in CSV files, i found the best way to utilize this script is to do an "initial Seeding/Dump" since the beginning of Rate My Call policy being applied to the users, that will take very long depending on your data, but in my case a 7,000 Users over 3 months took about 14Hrs to complete;

but then  to avoid that going forward you can edit the downloaded module to automatically fill in your credentials and run it as a schedule task every week and get the last 7 days data only which can be less than a few hrs every week,

When you install the CxdCallData it will deploy the files in the folder C:\Program Files\WindowsPowerShell\Modules\CxdCallData\1.1.6.0 you can then  edit the line

$global:credential = Get-Credential -Message "Authenticate to Skype for Business Online"

to :

$O365_pass = cat 'C:\mypasswordfolder\Office365_securepass.txt' | convertto-securestring
$global:credential = new-object -typename System.Management.Automation.PSCredential -argumentlist "USERNAME@TENANT.onmicrosoft.com",$O365_pass

so after that i created a script to create the list of users based on their RMC policy and collect them in a CSV file and later call that module and pass that file; and my script is then added to the task scheduler to run every 7 days

Import-Module LyncOnlineConnector
$O365_pass = cat 'C:\Folder Path\Office365_securepass.txt' | convertto-securestring
$myO365cred = new-object -typename System.Management.Automation.PSCredential -argumentlist "USERNAME@TENANT.onmicrosoft.com",$O365_pass
$filename="C:\Folder Path\"+(Get-Date -format d).Replace("/","-")+"users.csv"
$CSSession = New-CsOnlineSession -Credential $myo365cred
Import-PSSession $CSSession -AllowClobber
Get-CsOnlineUser | ? {$_.Clientpolicy -match "RateMyCallPolicy"} | select-object UserPrincipalName | Export-Csv $filename
Remove-PSSession $CSSession

Get-CxdCallData -ReportSavePath c:\SfB\Reports -NumberOfDaysToSearch 7 -CsvFileWithUsers $filename

Below is the Export of the Task Scheduler in XML

now as you see it collects all reports to c:\SfB\Reports; you can only copy the SFB-UserFeedback-YYYY-MM-DD HH-MM-SS.CSV files to a folder lets call it c:\SfB\Reports\RMC

now we will need to aggregate all the data in one file; so what we will do is using Excel queries run the following :

  

In the Advanced editor paste the following Query

let
Source = Folder.Files("C:\FOLDER PATH\Report\RMC"),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Content", type binary}}),
Content = #"Changed Type"[Content],
#"Converted to Table" = Table.FromList(Content, Splitter.SplitByNothing(), null, null, ExtraValues.Error)
in
#"Converted to Table"

Then do the following steps:

Select the last step from the Applied steps and expand the drop down button.

Click on OK

Select the DiagID Column and then from Home>Remove Rows>Remove Duplicates

Rename The query to RMC and then Close and Load

Now you will get a Concatenated Excel Sheet of all the RMC User feedback reports in CSV from the Specified folder; make sure you only have those reports and nothing else in the folder, you can keep adding the reports there and Refresh the Excel sheet query to aggregate all files and build the new records.

After we had all results aggregated we will need to add some information that will help us build our reports with relation to our Network.

first we will add the functions that can calculate subnets in the Excel sheet, start by pressing ALT+F11

then Insert new Module as Shown here:

Save the Macro and close the editor and then save the Excel sheet as Macro Enabled format.

now we have the functions that can reverse lookup an IP to a Subnet , but we need to import the data to the Excel sheet and then do more steps..

Now we will download the building data and open an empty sheet in the same Excel file that we have created and then Rename the Sheet to Subnets

Then on the first Column A write the following Formula in the first cell:

=IF(ISBLANK('C:\tmp\[BuildingDATAFILE.csv]BuildingDATAFILE'!$A2),"",CONCATENATE('C:\tmp\[BuildingDATAFILE.csv]BuildingDATAFILE'!$A:$A,"/",'C:\tmp\[BuildingDATAFILE.csv]BuildingDATAFILE'!$C:$C))

Replace BuildingDATAFILE with your Building data file name and path.

Fill down the rest of the column with this formula:

  • Select and copy the cell containing the formula and press CTRL+SHIFT+DOWN to select the rest of the column
  • Fill down by pressing CTRL+D
  • Use CTRL+UP to return up

 

Now you will get the Subnet and Mask in Column A; we have to sort them

In the same sheet select Column B

type the formula, =iPsortArray(A:A)
press Ctrl+Shift+Enter instead of Enter

Now we have them in sorted order in Column B; then on Column C we will add a new Formula to do vlookup for the Subnet name from the data building file.

in Column C type the following Formula:

=VLOOKUP(B1,'C:\tmp\[BuildingDATAFILE.csv]BuildingDATAFILE'!$A$1:$B$5,2,FALSE)

now we got the subnet sorted and with their corresponding names.

lets go back to the first sheet and add a coulmn called From Subnet and To Subnet corresponding to the to and from IP address

then add the formula respectively to reverse lookup the IPs

=IpSubnetVLookup([@FromIPAddr],Subnets!$A$1:$B$5,3)

=IpSubnetVLookup([@ToIPAddr],Subnets!$A$1:$B$5,3)

Finally as we got all the information we need we will open Power BI Desktop to import this information

Open a new Query

then Click Advanced Editor and enter the following query

let
 Source = Excel.Workbook(File.Contents("C:\tmp\Book1.xlsm"), null, true),
 Sheet1_Sheet = Source{[Item="Sheet1",Kind="Sheet"]}[Data],
 #"Promoted Headers" = Table.PromoteHeaders(Sheet1_Sheet, [PromoteAllScalars=true]),
 #"Removed Duplicates" = Table.Distinct(#"Promoted Headers", {"DialogId"}),
 #"Removed Blank Rows" = Table.SelectRows(#"Removed Duplicates", each not List.IsEmpty(List.RemoveMatchingItems(Record.FieldValues(_), {"", null})))
in
 #"Removed Blank Rows"

Click Close and Apply

Then all of the Excel information will be imported into Power BI we will start some interesting reports:

first we will need the From Subnet in percentage as well as the To Subnet

Then we will add the Ratings and the Count of Ratings only

as you can see if you clicked on these ratings it will show you the percentage of the fro and to subnet names that the users are reporting Very bad, fair, good or excellent from.

you can add as well the users by rating count which will show you the users who most rated poor , very bad, so you can address their issues.

 

Now moving to the next part where we Analyse the user sentiment, Thanks to DataCHant blog for helping me out in this task \

(http://community.powerbi.com/t5/Community-Blog/Text-Analytics-in-Power-BI-Extraction-of-key-phrases-from/ba-p/88487)

i am copying most of his post blog here as i had to do the exact steps with minor changes

Before we start Sentiment Analytics 

Prerequisites

To do this tutorial, you need:

 

Preparing the API queries - A parameter and a query function

 

In this section we'll prepare the advanced Power Query code that we'll need for the Key Phrase API.

 

In the Query Editor's Home tab, click Manager Parameters, then select New Parameter.

 

In the Parameters dialog, set APIKey as Name and paste the API Key that you obtained from Microsoft Cognitive Services into the text box Current Value.

When you are done, click OK.

 

Screenshot_28.png

 

In the Query Editor's Home tab, click the drop down menu below the icon of New Source and select Blank Query. Still in Home tab, click Advanced Query and paste the following code:

 

(Source) =>
let
    JsonRecords = Text.FromBinary(Json.FromValue(Source)),
    JsonRequest = "{""documents"": " & JsonRecords & "}",
 
    JsonContent = Text.ToBinary(JsonRequest, TextEncoding.Ascii),
    Response =
        Web.Contents("https://westus.api.cognitive.microsoft.com/text/analytics/v2.0/keyPhrases?",
            [
                Headers = [#"Ocp-Apim-Subscription-Key"= APIKey,
                           #"Content-Type"="application/json", Accept="application/json"],
                Content=JsonContent
            ]),
    JsonResponse = Json.Document(Response,1252)
in
    JsonResponse

 

 

Click Done in the Advanced Editor, and rename the new query to GetKeyPhrases.

Screenshot_31.png

 

 

Note: Now in Queries pane, you will notice that the new query GetKeyPhrases has an fx icon. The query above is not a normal query. It is a query function that receives a table as an input, converts it into a JSON format, sends it to Microsoft Cognitive Services and returns the JSON response.

 

Screenshot_32.png

 

Right click on the Sheet1 in the left Queries pane, and click Reference.

 

Rename the query Sheet1(2) to Sentiment Results. To rename the query, right click on it and click Rename.

 

Note: In the next step we will select the columns in our data that contain the actual text for analysis and a unique ID for each text. The unique ID is required by Microsoft Cognitive Services API. The unique ID will help us to map the Sentiment scores in the response to the relevant text. In our data, we use the diagIDs as unique IDs.

In Home tab of Query Editor, click Choose Columns, unselect all columns, then select DiagIDand FeedbackText and click OK.

 

Now, let's rename the columns. DiagID should be renamed to id and FeedbackText should be renamed to text. This step is critical. Don't miss it. The Sentiment Analysis API requires these names.

 

Screenshot_17.png

 

Note: If you need to perform analysis on text in French, Spanish or Portuguese, you can create another step here and define a custom column whose name is language and is value is "fr", "es" or "pt" (For French, Spanish or Portuguese). Since English is the default language in the API, we skip this step.

 

In the next step, we will remove rows with empty text messages. There is no point in sending such rows for Sentiment Analysis, and the service will return errors if we try to.

 

Click in the filter icon of the column text, and then click Remove Empty.

 

Screenshot_22.png

 

Rename the column message to text. This is crucial. Later on we convert the table into a JSON format with the name text.

 

In Add Column tab, click Custom Column.

Set language as New column name, and = "en" as Custom column formula. Then click OK.

 

Screenshot_44.png

 

Note: The Text Analytics Key Phrases API support the following languages: English (en), German (de), Spanish (es) and Japanese (ja). You can use any of these codes if your text is in those languages.

 

 

Group data to sub-tables of 1000 messages each

 

Microsoft Cognitive Services allow us to send 1000 different messages on each API call as part of the Key Phrases API. In this part, we'll group the table into sub-tables of 1000 rows.

 

In Add Column click Index Column.

 

Screenshot_37.png

 

Select the new column, Index, and in Transform tab, click Standard, then select Integer-Divide.

 

Screenshot_38.png

 

In Integer-Divide dialog, set 1000 as Value and click OK.

 

Screenshot_39.png

 

Now the values in column Index are all 0 in the first 1000 rows, all 1 in the next 1000 rows, and so forth.

Select the column Index, and click Group By in Transform tab.

 

Screenshot_40.png

 

In the Group By dialog, ensure that Index is selected in the drop down menu Group By.

Set sub-table as the text in New column name.

Select All Rows as Operation, and click OK.

 

Screenshot_41.png

 

After the grouping step, we have a new column sub-table that contains our tables in bulks of 1000 rows each (excluding the last row that has the remainders).

 

 

Screenshot_66.png

 

 

We can delete the column Index, and click Invoke Custom Function in Add Column tab.

 

In Invoke Custom Function dialog, set GetKeyPhrases as Function Query and select sub-tableas the column. When you are done, click OK.

 

Screenshot_67.png

 

Delete the column sub-table, and click the expand button in the left side of the header GetKeyPhrases.

Ensure all columns are selected in the expand pane, uncheck Use original column name as prefix, and click OK.

 

Screenshot_69.png

 

Delete the column errors.

 

Click on the expand button in the header of column documents, select all columns and click OK.

 

Screenshot_49.png

Click on the expand button in the header of column KeyPhrases.

 

Screenshot_50.png

 

Finally, we have a new column with a key phrase for each message id. You should note that we will usually have multiple key phrases per message, so our table is now expended to multiple rows per message id.

 

For a final cosmetic touch, let's capitalize each word in column KeyPhrases:

Select the column KeyPhrases, right click on its header, select Transform and then select Capitalize Each Word.

 

Screenshot_70.png

 

We have completed the extraction of key messages. It's time to move to the modeling and visualization.

In the Query Editor window, click Close & Apply.

 

Feeding Key Phrases to a WordCloud Custom Visual

 

We are almost done. It's time to move to the visualization part. We'll now learn how to create a simple WordCloud visual with our key phrases.

 

After completing the last two parts, we now have two tables FeedbackText and KeyPhrases. We can create a relationship between column id in both tables (if Power BI Desktop didn't detect them automatically). To do it, go to Relationships view, and drag and drop the column Diagid from  FeedbackText to KeyPhrases as shown here.

 

Screenshot_71.png

 

Download WordCloud (from here), and import it to your report .

 

Click the Report view, and add a WordCloud to your report. Drag and drop the column KeyPhrases to Category and count of  KeyPhrases to Value .

 

In Format tab in Visualizations, turn on Stop Words and Turn off Rotate Text.

 

Under section General, turn off Word-breaking.

 

Screenshot_58.png

You can now resize the WordCloud visual, and see the size of the key phrases is defined by the number of posts.
