Troubleshooting errors that occur during monitor addition and data collection in Microsoft 365 monitor (For versions 16310 onwards)

Troubleshooting errors that occur during monitor addition and data collection in Microsoft 365 monitor (For versions 16310 onwards)

From Applications Manager version 16310 onwards, Microsoft 365 monitor will use Microsoft Graph API as the primary mode of data collection. 
We have migrated from PowerShell to Graph API as Microsoft 365 PowerShell commands were taking more time to execute for huge resources and required Administrative user privileges for execution of the commands. Microsoft provides  archived data alone in the Graph API. To monitor live data, use the PowerShell mode considering the user privileges and the time taken to fetch huge resources.

Prerequisites: 

  1. Ensure that you have met all the prerequisites for the Microsoft 365 monitor.
If you have enabled the Enable monitoring via PowerShell option, refer the links given below:
  1. For Exchange Online troubleshooting, refer to this KB.
  2. For SharePoint Online troubleshooting, refer to this KB.

The below errors are the possible causes that are mentioned next to the keyword 'Reason' of the UI error messages on the monitor. For example, Unable to collect Service Health data. Reason: Required permission 'ServiceHealth.Read.All' is missing to collect the Service Health Data refer to the Required permission to collect the data troubleshooting steps.

How to fix "Unable to parse endpoints in CSV."?

To edit/add endpoints in Microsoft365 monitors, one can edit the Microsoft365_Endpoints.csv file which is present under <APM_Home>/working/conf/Microsoft365Configurations/ folder. The maximum number of endpoints allowed per monitor type is 100.
The file follows the below format for Microsoft365, ExchangeOnline, SharePointOnline, and MicrosoftTeams monitors:
  1. Endpoint,Port
  2. #<Monitor Type> starts,
  3. Host,Port
  4. #Can comment a line with a # symbol at the start of the line if a particular endpoint is not needed for monitoring.
  5. #<Monitor Type> ends,
Sample file to indicate how to specify endpoints:
  1. Endpoint,Port
  2. #Microsoft365 starts,
  3. api.login.microsoftonline.com,443
  4. clientconfig.microsoftonline-p.net,443
  5. #Microsoft365 ends,
  6. #ExchangeOnline starts,
  7. smtp.office365.com,587
  8. outlook.office365.com,443
  9. #ExchangeOnline ends,
