Configuring Statistics metrics

Statistics metrics are enabled per column through the Configure Structural Metrics panel. Once active, thresholds and settings are managed on the asset’s Metric tab.
  1. Navigate to Metric in the top navigation.
  2. Click Configure Structural Metrics (the waveform icon in the toolbar).
  3. In the Map Asset/Attributes to the Metrics search field, select the target asset and column.
  4. Click the Statistics tab and check the specific statistics to enable (or Select All Statistics Metrics).
  5. Click Apply.
The selected metrics begin collecting data on the next profiling run. To adjust thresholds, navigate to Asset → open the asset → Metric tab → STATISTICS filter chip → click the metric → Edit configuration (pencil icon).

Configuration options

​
Threshold

Choose how Prizm determines when to raise a Statistics alert. Automated Threshold — System-generated thresholds based on the historical baseline for each statistic. Prizm computes how many standard deviations the current value is from the baseline and maps deviation magnitude to alert priority: Custom Threshold — User-defined absolute limits for triggering alerts. Useful for financial columns with known valid ranges — for example, alert if Mean transaction amount exceeds $10,000 or if Sum deviates by more than ±5% from the expected daily total.

​
Semantic context

Statistics metrics are automatically tagged with:
  • Dimension: Reliability
  • Domain: Inherited from the asset’s domain assignment
To update the semantic context or assign Owners, open the metric in Edit configuration mode and scroll to the Semantic context and Owners sections.
