Fields

DeclaredPageCount is the page count accepted from the page-tree root
MaterializedPageCount is the number of populated page slots
ObjectIndexCapacity is the allocated indirect-object hash capacity
AccessCount counts page-object access requests while telemetry is valid
CacheHitCount counts requests served by an already populated page slot
MaterializationCount counts pages resolved individually
TraversedNodeCount counts child nodes inspected during individual resolution
FullExpansionCount counts complete page-tree expansions
MaximumDepth is the deepest individually traversed subtree level
PlaceholderBytes is the byte size of the page placeholder array
Active is True while unresolved page slots remain
Valid indicates that the current counters describe a lazily initialized page tree
