# flowrate

**Explanation**

The flowrate NDM is an opt-in system NDM designed to fire if the rate of flows received by Netography from a particular flow source exceeds a certain threshold within an hour.

**What to Look For**

The flowrate NDM can be enabled and configured with different thresholds in order to monitor the health of flow reporting, create an alert when flows have begun from a particular device, or identify circumstances in which high rate of flows are being reported by a particular device due to high amounts of network utilization.
