RRD Graphs for IPsec not showing anything

[pdrass]

I have an ALIX board and PFSense version:

2.1.5-RELEASE (i386)
built on Mon Aug 25 07:44:26 EDT 2014

I have a HIFN card installed and it's recognized on the system summary.  I do NOT have any custom options set for custom acceleration card configured because it said on that page that would take priority over the HIFN card.  We don't want that!

To my knowledge everything is working but RRD graph's don't show me any data (see attached pic).

Does this mean VPN traffic isn't going through the HIFN or just the opposite, that the HIFN is being used and therefore PFSense can't monitor that traffic?

I don't know how to confirm VPN is going through the HIFN I can only guess :-(

Any insight would be appreciated!

Thanks!
