Describe the bug

So it seems that my insight aggregator and ntopng plugins were failing because the system was out of hard drive space. Once i looked into logs i could see that they were telling me that very blatantly. I wanted to make sure so i disabled my ntopng deleted the data directory in /var/db. I also reset netflow data and rrd data. After doing this everything is running again. The part that confuses me is the disk usage on the GUI dashboard showed i was only using 60% of my hard drive. Why would it show this if the hard drive was that full?

To Reproduce

Steps to reproduce the behavior:

1. Go to GUI dashboard and look at disk usage.

Expected behavior

I would expect the GUI to show the correct disk space usage.

Describe alternatives you considered

Maybe the GUI is not pulling from the right data.

It's going to be hard to see what it was. I suggest keep an eye on usage now. It should naturally grow and show here the result of going to root and df i.e.:

#cd /
#df -alh
