An Overview of the Workbooks Page

Firstly, you have to select Workbooks page from the Microsoft Sentinel navigation blade to view following icons:
  • The Workbook Header- There are total number of workbooks saved, to the right of it total number of templates, and far-right side is the total number of templates that can be updated under the Refresh and Add workbook buttons.

  • The Templates View- The My Workbooks and Templates tabs can be seen below the workbook header where the My Workbook tab shows all the accessible workbooks including shared as well personal whereas the Templates tab shows all the templates available to be used. You can select any tab. At the My Workbooks tab, every report have a green bar since every report is available to view. After that there is an icon representing the company that created the template, then the template name, and the company's name under this. 

  • Workbook Detail View- After selecting a workbook, its information can be seen on the details window on the far-right of the Workbooks page which will also show the icon, name, and company name at the top of the screen. The Relevant Data connectors can be seen under the Required data types showing which data connectors are used to ingest the needed data and scrolling down will also show one or more reports representing how the report will look.

  • Missing Required Data types- The complete list of the required data types are present under the workbook detail view and lists one or more data types needed for this workbook to function correctly. The green checkbox icon represents the availability of the needed data source in your environment while the cross check icon shows the otherwise. You can also create a workbook from a template without any required data types although it will have no information and may lead to an error.

  • Saved Template Buttons- There are a series of buttons at the bottom of the screen the change according to the template saved or not. Each of these buttons are described as follows-  

  1. If the template is saved as a workbook, then the first button will be View saved workbook which can help you to look at the workbook you have created from the template along with the changes you have made to it. However, if the template is not saved as the workbook, then the Save button is shown which will help you to create a new workbook from a template. 
  2. Next is the View template button which will show whether or not you have saved the template as a workbook already. It allows you to have a fully interactive view of the template although you can only refresh it but cannot save or modify it from this view.
  3. The third button will depend on the saving or not saving of the template as a workbook. If the template is saved then the Delete button will be shown which will cause a validation pop up to appear on clicking and on confirming, the workbook along with all the changes you have made will be deleted.  

If the workbook is created without any help of an existing template, then the View template button will not be shown.

If it is being considered to be used, then following areas should be covered during a Microsoft Sentinel deployment project: Consider the timelines and the strategy for a migration to AMA (Azure Monitor Agent) before the MMA end-of-life.  Consider the central deployment and management methodology for MMA.
