Question:
Why when restarting the Data Aggregator (DA) a lot of WARN messages like the following are seen in DA's karaf.log:

....
WARN  | ository-thread-4 | 2018-04-18 10:19:33,421 | atedMonitoringProfileManagerImpl | atedMonitoringProfileManagerImpl 1069 | nager.core.profiles.impl |       | The collection IDs and vendor certs are not complete for item 14

WARN  | ository-thread-4 | 2018-04-18 10:19:33,440 | atedMonitoringProfileManagerImpl | atedMonitoringProfileManagerImpl 1069 | nager.core.profiles.impl |       | The collection IDs and vendor certs are not complete for item 14
....

What is the reason for these messages?
Does they mean there is any problem with device or metrics discovery?

Answer:
These messages are benign.
They are related to the out-of-the-box Metric Family 'NormalizedVirtualServerServices1Info' not having a VendorCertID value associated.

This has been reviewed by the product Development team and the related code has been refactored for upcoming CAPM release 3.6, so this message will not be issued anymore.
