If they need no special semantics, why would one want to add counters
and gauges?
And for availability, do we really want to have feeds deliver random
numbers
as their availability and then in the UI show the random numbers as we
can
not determine what availability state they mean?
If all you have is a double, then everything will look like
2.999999975687 pentium processors :)
What I meant is that we shouldn't care about how the data is stored, if
it's a counter, a gauge, a string. It's a "value point" in time.
What matters is how we query this data. For example, if you're working
with a counter you'll probably be interested in applying a derivative
function.
