Hi Andreas,
CBM 2.5 integrated with fresh VCD 5.1/5.1.1 does not suffer from the issue mentioned by Justin in his comment. It is an issue for older version of integration and is corrected in CBM 2.5 integrated with fresh VCD 5.1/5.1.1.
The logs which you have mentioned are only info logs, and do not seem to affect your environment. VCD DB details are required by CBM only if VCD is 1.5.1 or older or in case of upgrades. Since your setup is fresh, the logs you have mentioned do not point to any discrepency in your setup.
Do you see any other ERROR, WARN or FATAL logs in your VCD DC logs?
Thanks,
Piyush
