That visibility helps you **prioritize incidents and data quality** on the assets that drive the most load and downstream impact, and get a **clearer end-to-end view** of what is happening in production. ## Usage in the Catalog Open the **Catalog** and select the **Metadata** tab. Table assets include a **Usage** column with a **usage indicator** so you can compare relative activity at a glance. Catalog Metadata tab showing the Usage column with usage indicators and a tooltip with percentile, date range, query count, and unique users ### Tooltip details Hover the usage indicator for a specific asset to open a tooltip with: * **Percentile rank** — How this table’s query volume ranks against every other table. For example, **72nd percentile** means its query volume is **greater than or equal to** that of **72% of tables** in your environment. * **Reporting period** — The exact **30-day** date range the metrics are based on (for example, March 15 – April 14, 2026). * **Query count** — Total queries against the table in that period. * **Unique users** — Distinct users who ran queries against the table in that period. ## AI agents The same usage signals are available as **context** to Elementary **AI agents**, so you can ask natural-language questions that depend on real consumption—for example, **“Show me the top 5 most used tables.”** AI assistant response with a ranked list of the most queried tables ## Related * [Data Catalog](/cloud/features/collaboration-and-communication/catalog) — Overview of catalog navigation, metadata editing, and collaboration workflows. * [AI agents](/cloud/ai-agents/overview) — How Elementary’s agents use catalog and observability context.
