    if (nodeId != null) {
        NodeMemoryUsage memory = nodeService.memory(NodeId.nodeId(nodeId));
        if (Objects.nonNull(memory)) {
            print("Memory usage : %s", memory.toString());
        } else {
            print("Node %s doesn't exists");
        }
    } else {
        Collection<NodeMemoryUsage> memory = nodeService.memory().values();
        printMemoryUsage(memory);
    }
