Metaplane introduces new monitor types, including SUM, Percent Negative, and Percent Zero, to enhance its monitoring capabilities for various business metrics. The SUM monitor helps track important metrics like revenue or product usage time. The Percent Negative monitor identifies negative values in specific columns, while the Percent Zero monitor ensures that certain column values are either zeroed out or not spiking unexpectedly. These monitors can be applied to any numeric column within Metaplane's platform.
