字段

• DeclaredPageCount 是从页面树根节点接受的页数
• MaterializedPageCount 是已填充的页面槽位数
• ObjectIndexCapacity 是已分配的间接对象哈希容量
• AccessCount counts page-object access requests while telemetry is valid
• CacheHitCount 统计由已填充页面槽位响应的请求数
• MaterializationCount counts pages resolved individually
• TraversedNodeCount counts child nodes inspected during individual resolution
• FullExpansionCount counts complete page-tree expansions
• MaximumDepth 是单独遍历过的最深子树层级
• PlaceholderBytes 是页面占位符数组的字节大小
• Active 是 True while unresolved page slots remain
• Valid 表示当前计数器描述的是一棵惰性初始化的页面树
