the appliance is running about 29 days. Now my dashboard is pretty empty.
All widgets show "no data"
I cannot find any special messages in the logs regarding this issue.
The syslog is full of events that are not related to the issue. By the way, the AA Server reboot helped to resolve the issue for 2 of 3 customers. For the last one, we have an open internal ticket (OCTCR28D300123).
Regarding the Dashboard issue, let's see if it will be resolve after reboot. If no, please provide the uwsgi.log and output for "docker ps -a".
This can happen if you don't have a busy system, as the defaults for the dashboards are 1hour. Expand their time reports to 1 day or longer and see if there is more generated.
