There is no rule of thumb as far as I know. Shred adds ticks to the dot and doesn't resnapshot, Festering Strike adds ticks to the dot and doesn't resnapshot. Touch of Chaos and Fel Flame add ticks to the dot and do resnapshot.
My understanding is they choose whether or not an ability resnapshots on an individually basis and abilities that perpetually refresh a DoT tend to resnapshot, Rip, for whatever reason, being the exception to that rule.
A hunter's Chimera Shot
will refresh the duration of Serpent Sting
to it's full duration as well. I wonder if Serpent Sting behaves like Rip and keeps its original stats when refreshed by Chimera Shot in this way.
Could be wrong but I don't believe it does. I believe Rip is the only full refresh mechanic that does not resnapshot.
And the only thing that isn't in the snapshot state of a dot is Crit Multiplier which behaves dynamically, everything else (AP, SP, crit, haste, mastery if applicable) snapshots and as far as I know there are no exceptions to this.
E: Cobra Shot and Chimera Shot both resnapshot.
