The barbarian passive, "Pound of Flesh" increases the chance of finding a health globe by 25%.
What are the mechanics of health globes spawns? Does each monster have a chance to spawn a health globe (which Pound of Flesh increases) or is it based on some other mechanic? I'm curious to see often I would see the benefit of changing my passive.

Blizzard has recently published some data on this on the official guide:
In addition, with the superunique and act bosses, you can look at their health bar to see when a globe might drop:
Regarding the "varying chance" normal monsters have to drop, typically the stronger the individual monster is, the higher the chance. Monsters that come in groups and are easily felled have a relatively low chance of dropping, while solitary, tough monsters - for example living trees, or those huge wall-climbing siege monsters in Act 3, are guaranteed to drop a globe upon death.
