Description
Microsoft Sentinel relies on api.loganalytics.io, which is the documented API endpoint for Azure's Log Analytics. An example of issued request is the following one:
POST https://api.loganalytics.io/v1/subscriptions/REDACTED/resourceGroups/REDACTED/providers/Microsoft.OperationalInsights/workspaces/REDACTED/metadata?select=categories,solutions,tables,workspaces
The api.loganalytics.io domain is however indirectly blocked as it is a CNAME for api.monitor.azure.com which is on the block-list.
> api.loganalytics.io
Server: REDACTED
Address: REDACTED
Name: api.loganalytics.io
Addresses: ::
0.0.0.0
> set type=CNAME
> api.loganalytics.io
Server: REDACTED
Address: REDACTED
api.loganalytics.io canonical name = api.monitor.azure.com
This causes Azure to break.

While I have added an exception for it, it might be worth considering whether the api.monitor.azure.com block is intentional.
