Minimum Segment Size for Metric Monitors

Segmented Metric Monitors now support a minimum segment size setting. Configure a floor by absolute row count or as a percentage of total rows — segments below the threshold are still collected and visible in the monitor, but Monte Carlo will not generate thresholds or alert on them.

In high-cardinality segmented monitors, infrequent or low-volume segments often behave differently than the rest — shifting quickly, appearing and disappearing without reflecting the stable patterns worth alerting on. This setting lets you define which segments are meaningful enough to monitor, keeping alerting focused on the data that matters.
