Hello, Im having an issue with my sonicwall firewalls. they show 15 minute blank spots in reporting. Primary and fail-over devices, at different times. nothing stands out in the logs, and no one is screaming that internet was down for 15 minutes. Suggestions on getting to the bottom of this? is it just a graphing failure? (see attached screen shot) [image: Inline image 1]
