import io.milvus.param.*;
import io.milvus.grpc.GetMetricsResponse;

GetMetricsParam param = GetMetricsParam.newBuilder()
        .withRequest("{\"metric_type\":\"system_info\"}")
        .build();
R<GetMetricsResponse> response = client.getMetrics(param);
if (response.getStatus() != R.Status.Success.getCode()) {
    System.out.println(response.getMessage());
