+## 9. Monitoring in the Feast UI
+
+The Feast web UI includes a built-in monitoring dashboard accessible from the **Monitoring** item in the sidebar navigation.
+
+### What you see
+
+The monitoring page has three tabs:
+
+| Tab | Shows |
+|-----|-------|
+| **Features** | Per-feature metrics table with null rate, row count, freshness, and health status |
+| **Feature Views** | Aggregated data quality per feature view |
+| **Feature Services** | Aggregated metrics per feature service |
+
+### Filters
+
+At the top of the monitoring page you can filter by:
+
+- **Feature View** — scope to a specific feature view or view all
+- **Granularity** — select Baseline, Daily, Weekly, Biweekly, Monthly, or Quarterly
+- **Source** — filter by batch or log data source
+- **Start/End Date** — filter metrics to a specific date range (disabled for Baseline since baseline uses all data)
+
+### Feature detail page
+
+Clicking any feature row navigates to a detail page showing:
+
+- **Distribution histogram** — expandable/zoomable chart of the feature's value distribution
+- **Statistics panel** — null rate, mean, stddev, min/max, percentiles (p50–p99)
+- **Granularity dropdown** — switch between computed granularities and baseline
+- **Time Series Analysis** — trend charts for aggregate metrics drift (Mean/P50/P95) and null rate evolution over time
+
+### Computing metrics from the UI
+
+Click the **Compute Metrics** button in the page header to trigger an `auto_compute` job. This computes all granularities for all feature views (or the selected feature view if filtered). Results appear after the table refreshes.
+
+The **Refresh** button re-fetches already computed metrics from the backend without triggering new computation.
+
+### When no data is available
+
+If no metrics have been computed yet, the page shows a prompt:
+
+> No monitoring data has been computed for this project. Click "Compute Metrics" to run data quality analysis on your feature views.
+
+If the monitoring backend is unreachable, a warning banner appears:
+
+> Could not connect to the monitoring API. Make sure the Feast registry server is running with monitoring enabled.
+
+### Enabling monitoring for the UI
+
+The monitoring page is always accessible in the sidebar. To see actual data:
+
+1. Add `data_quality_monitoring` to your `feature_store.yaml`:
+
+   ```yaml
+   data_quality_monitoring:
+     auto_baseline: true
+   ```
+
+   Or, when using the Feast operator, set this in the `FeatureStore` CR:
+
+   ```yaml
+   apiVersion: feast.dev/v1
+   kind: FeatureStore
+   spec:
+     feastProject: my_project
+     dataQualityMonitoring:
+       autoBaseline: true
+   ```
+
+2. Run `feast apply` — this computes baseline metrics automatically
+3. Schedule `feast monitor run` (or click "Compute Metrics" in the UI) to generate daily/weekly/monthly metrics
