I had a bunch of Resource Manager VMs configured to use Diagnostic Settings with all VMs using the same storage account.
I accidentally deleted the storage account these VMs were using for diagnostics. Then, I created a new Storage account with the same name, and manually changed the storage account for each VM to use this new storage account under "Diagnostic Settings". I also made sure the "Boot Diagnostics" checkbox was checked under "Diagnostic Settings", and that "Status" was set to "On".
I created the new storage account as "Standard" (Performance) and "Locally-redundant storage" (LRS) in the same region.
Previously, when I rebooted a machine, I could see it's screenshot under "Boot diagnostics". With my new configuration, the "Boot diagnostics" screen is always blank even after multiple reboots.
Is there some additional step I need to do to get "Boot Diagnostics" to again show me these screenshots? Did I do something wrong in setting this up?
