After the addition Ciscoworks should automatically start managing the devices. The first thing it would do is to collect Inventory details to get it managed.
When you simply add a device using IP and login/snmp credentials via add/import, the device should appear unknown and once the basic inventory is done, ciscoworks should show device family icon (switch/router/FW/Voice etx), which should reflect LMS has started managing you device(s).
It seems "logs" is not clear on what is exactly you dont get.
Make sure the Credentials are correct which you can check via Credentials verification job, from:
Inventory > Job Browsers: Device Credential Verification
As Ciscoworks LMS is combinations of various modules segregated feature-wise like configuration, Fault Management, IP SLA etc. For more details please check the following End-User Guide Section :
