Recently the 29th of Feb was the date the classic app insights was retired and we are supposed to migrate them to workspace based so they have a log analytics workspace underneath them. If you havent done this yet then you probably got this email.
The email tells me the subscriptions that have them but to make life a bit easier the below resource graph query will help you see which ones are still outstanding to be updated.
resources
| where ['type'] contains "microsoft.insights/components"
| extend workspace = properties.WorkspaceResourceId
| where workspace == ""
You can also use the below query to track how many you have converted or still have to do
resources
| where ['type'] contains "microsoft.insights/components"
| extend workspace = properties.WorkspaceResourceId
| extend IsWorkspace = iff(isnull(workspace), "false", "true")
| summarize count() by IsWorkspaceIts pretty easy to do the migration, just follow the link below:
