When the data collector initiates the gRPC connection, the SR OS node assumes the role of the gRPC server and the collector is the client. This is referred to as dial-in telemetry, where the SR OS node pushes data to the receiver (collector). Figure: Dial-in telemetry session shows the telemetry session initiated from the collector to the SR OS node via the Subscribe RPC.
