> GraphiteSink currently outputs an equals character "=" as part of the metric key that it outputs to graphite. Graphite doesn't currently support the "=" as part of a key, and current Graphite trunk breaks when trying to query a metric containing this character.
> This can be worked around with wildcarding (carbon appears to store it correctly), but it'd be good if metrics sent to graphite used only supported characters.
> I propose that we simply use a supported character such as '_'.
