My graphs were running for a few hours and then all quit aside from the WANGW-quality graph. The others were all blank in the gui.
I too am running embedded 2.0-RC1 (i386) built on Fri Mar 4 14:40:57 EST 2011. Hardware is a Watchguard Firebox X700 (I think). I restarted the rrd graphing and things seem to be working again.
I'm still learning my way around (coming from m0n0wall). I can't remember if I created the WANGW gateway or GW_WAN, but I created one of them when setting it up, then realized I didn't need to create it. I can't remember where either.
This is before the

And see this in the logs when stopping and starting rrd.

We'll see how long it goes for.
