Hello again,
When we look at the log we see that you do have snmp and SMH installed but the snmp sub agents either are not installed or are not all running. You should logon to the SMH of the server you tried to discover and see if this page looks complete. If it does'nt please look if all subagent services are running. Then your server is a Windows 2008 or higher version you could try the wbem agent and set that as the datasource if you haven't done so already.
Then the SMH looks a lot better, but when we look at the log you don't have a account setup to read this wbem/wmi . The use you have to co configure needs to be able to read the wbem/wmi information. A local admin rights account is more that enough. Less can also work but just start with an account that has lokal admin rights on the server you want to discover.
If you don't know how to setup these credentials just let me know.
Kind regards,
Andrew
