Example 1 with SimpleResponse

use of io.grpc.benchmarks.proto.Messages.SimpleResponse in project grpc-java by grpc.

the class AsyncClient method doUnaryCalls.

        long lastCall = System.nanoTime();

        @Override
        public void onNext(SimpleResponse value) {
        }

        @Override
        public void onError(Throwable t) {
            Status status = Status.fromThrowable(t);
            System.err.println("Encountered an error in unaryCall. Status is " + status);
            t.printStackTrace();
            future.cancel(true);
        }

        @Override

            // Record the latencies in microseconds
            histogram.recordValue((now - lastCall) / 1000);
