I have created an application in Azure AD and given it read permission to AppInsights API.
Pasted secret, directory ID and stuff into the fields, but no subscription loads:
I am facing the same issue, Grafana support team given me this link to refer. Azure Monitor | Grafana Labs
no luck so far, will keep you updated if i get it resolved.
Did you create classic or workspace based app insights? If the latter, can you try giving Log Analytics based access and see if that resolves your issue?
Good catch @mitulmk , our ARM templates created just the classic Appinsight resource.
migrating existing application insight resource to worksapce-based. hope this would resolve my issue.
