I think I have the sequence of events correct.
With FreeNAS 8.0.1 Release I had email reporting and the graphical reports (RAM and CPU usage, etc.) working OK.
After upgrading to 8.0.2 Release email reporting no longer worked, and I don't recall whether the graphical reporting worked initially or not; it definitely did not work toward the end.
Yesterday I tried updating to the then-latest nightly (FreeNAS-8.2-r8620-amd64.GUI_Upgrade.xz), which somebody suggested might be able to display the CPU temperatures from the command line. This resulted in a horrible mess: I could access the NAS box from Firefox, but all I got was one little System icon. ls /mnt/ from the command line showed none of my drives.
I reinstalled FreeNAS 8.0.2 Release and uploaded a saved config file. Now my drives are visible again and the email reports are working again, but the graphs on the Reporting page are all still blank.
