Did a quick search but too many threads on reporting. Here is my addition[;)]
I don't have any problems with reporting usually but last night I had to reset my astaro. I usually have a much higher uptime but last night the system had only been up for a few hours.
In my daily executive report, my network counts for traffic processed/connections handled are zero but as you can see in screenshot I have web traffic as well as email traffic being counted. So there is no way that I had no traffic or connections.
