# Grouped-by Monitors
By utilizing Group By monitors, data teams have the ability to highlight and define specific segments within a table, like those aggregated by values in a dimension column. Following this segmentation, monitors can be applied. This functionality enables teams to not only track the overall row count of a table but also monitor counts of its individual logical subdivisions.
The configuration process for Grouped-by monitors differs from the setup routine of other monitor types, here's how you begin setting up for Grouped-by monitors.
