-| Status                  | Description | Action
-| Unsupported Part Number | The detected part number is unknown or unsupported. | Call {suse} support and open a Service Request ticket to have the part number added to the product.
-| Physical Guest          | A client is reporting as virtual, but could be a physical client. | Check the client hardware data.
-| Guest with Unknown Host | A virtual client has an unknown host. | Check the virtual host manager (VHM) configuration to ensure it is reporting correctly.
+| Message                 | Type | Description | Action
+| Unsupported part number detected | Debug | The detected part number is unknown or unsupported. | Call {suse} support and open a Service Request ticket to have the part number added to the product.
+| Physical system is reported as virtual guest, please check hardware data          | Debug | A client is reporting as virtual, but could be a physical client. | Check the client hardware data.
+| Virtual guest has unknown host, assuming it is a physical system | Warning | A virtual client has an unknown host. During the matching process, it was treated as a physical system. This might translate into a wrong subscription assignment. | Check the virtual host manager (VHM) configuration to ensure it is reporting correctly.
 For Linux-based hosts using ``libvirt``, check that the host is registered, and that the virtual host system type is set correctly.
-| Unknown CPU Count       | Unable to determine how many CPUs a client has. {productname} will default to 16 CPUs. | Schedule a hardware refresh on this client.
+| System has an unknown number of sockets, assuming 16 | Warning | Unable to determine how many CPUs a client has. {productname} used the default value of 16 CPUs every time the number was relevant for matching a subscription. This might translate into a wrong subscription assignment. | Schedule a hardware refresh on this client.
+| Two subscriptions with the same part number are in a bundle | Informational | Two subscriptions were identified to be part of a bundle and, as result, they were merged together during the computation process. | No actions needed.
+| Two subscriptions with the same part number (and other properties) have been merged together | Informational | Two subscription shared multiple common properties and they were merged together during the computation process. | No actions needed.
+| Pinned match adjusted due to merged subscriptions | Informational | A user defined pin was updated since the chosen subscription was merged with another one. | No actions needed.
+| Subscription with unsupported part number and no associated product has been ignored. | Informational | An unknown subscription without any associated product has been detected and it was ignored during the matching process. | No actions needed.
