Gauge is an absolute value, like a temperature or the number of people in a room. Delta is a counter where each value is the difference between the current and the previous value. Each value represents how many things were consumed since last time a value has been sent. It's always compared to a counter that resets to 0 once you read it. -- Julien Danjou // Free Software hacker & freelance // http://julien.danjou.info
