The MoniLayerClients sample shows you how to use the FireDAC tracing and monitoring capabilities to show how an application is communicating with a FireDAC monitor client. To this end, the sample uses two different FireDAC monitor clients: FlatFile-client and Remote-client. To use both monitor clients, the sample uses two client link components: the TFDMoniFlatFileClientLink component and the TFDMoniRemoteClientLink component.
