CPU number and Disk size attributes for Server CIs


I am using HP UD 10.10 CP: 13.0.1179 on Windows OS.

I need to get the following attributes for a CI

 - CPU Number
 - Disk Size

I see that we have "Cpu" and "File System" CITs for the same but I am not able to figure out how can I relate these instances to the discovered CI and count the exact CPU number and Disk size for a particular CI.

Please can you help by providing inputs on how to resolve this.

Thanks in advance.
