This reports the amount of compressed configuration memory, in bytes, currently in use. Trending this value over time shows an admin how the node's configuration complexity, number of routes, PADs, and rule-like settings, is growing, which matters for capacity planning before the node runs out of configuration storage entirely. For example, watching this steadily climb after several rounds of adding new PVCs and routing entries would tell an admin the node's configuration footprint is growing and worth tracking against total available capacity.
