2017/01/04 9:48:19 [ERROR] [kaa_logging.c:803] (-6) - Failed to upload log bucket, id '1' (delivery error code '1')

What does this last line of error means ? From what i see , it looks to be failed to upload into database.

Would like to ask for the community's help! Your answers and solutions are very important to us !

Answer 1

It is an internal log appender error. By default, the Data Collection demo uses the MongoDB appender. Check that the MongoDB on your sandbox is up and running:

sudo service --status-all | grep mongo
