Linux machine attributes not getting discovered in UCMDB


I am using HP UD 10.10 CP: 13.0.1179 on Windows OS
I have performed the discovery for Linux devices. I am getting the data for some attributes but I am not able to get the data for below attributes for Linux devices.
   - Serial Number
   - Discovered Vendor
   - Discovered Model
   - Domain Name
I have executed the below jobs.
   - Ranges by ICMP
   - Host Connection by Shell
   - Host Resources by Shell
The user configured in the ssh protocol is a "sudo" user.
Please can you help by providing inputs on how to resolve this.

Thanks in advance.
