Hello,
I am trying to configure Discovery to discover AWS EC2. I have setup the Account, credential, and a schedule. After the discovery is completed, the EC2 instance showed up on the EC2 Virtual Machine Instance. When I clicked into the instance record, some of the details are not captured such as the CPUs, Disks, Disks size, and Memories. But the VM size, Availability zone, Object ID and VPC ID are captured. Are there anything else I need to setup to capture the missing information?
** I don't have the Cloud Management module.
Thank you,

The Virtual Machine (cmdb_ci_vm_instance) and the server (let's say cmdb_ci_win_server) are 2 different things and capture 2 types of information. The stuff you described was captured by your AWS discovery and is peculiar to the AWS Virtualization. To capture that other information, you need to run a standard horizontal discovery against the Windows server.
During the Windows discovery (I am talking probes here, sorry), it will run an Windows - Amazon EC2 probe and if it discovers you are an EC2 it runs the AWS Relationship Probe. During the sensor processing it takes the object_id field and finds looks for the vm_instance with the same object_id and then creates the relationship.
Patterns perform the same basic function in the Windows - Cloud Library and ensuing steps
All the CPU, DIsks, memory information are related lists associated with the cmdb_ci_win_server record, not the vm_instanec record. The relationship probe above connects the server and the vm_instance iwth a Virtualized by::Virtualizes entry in the Relationship table.
