Whether a realtime source's current-state gauges were read (M98l).
available — both gauges were read from the owning plugin's own service
and are current non-negative integers (a measured 0 is a real zero).
unsupported — the source's kind has no gauges (a backplane).
disabled — the source is not observing (not opted in, or closed), and the
gauge reader was not called. collection-failed — the read failed. Every
state except available carries null for both values.
