Ben Chambers commented on BEAM-1616:
------------------------------------
I believe the other metrics have solved/documented this:
Attempted = "Aggregate across all attempts at bundles"
Committed = "Aggregate across all committed attempts at bundles"
The point is that the general use case of a Gauge as a "I sampled this value at
this point in time" doesn't fit that model of aggregation.
So maybe it is enough to say that for a gauge, the attempted = committed = the
latest value observed?
