µC/TCP-IP maintains run-time statistics on interfaces and most µC/TCP-IP object pools. If desired, an application can thus query µC/TCP-IP to find out how many frames have been processed on a particular interface, transmit and /receive performance metrics, buffer utilization and more. An application can also reset the statistic pools back to their initialization initial values via appropriate API.
