Monitoring infrastructures is a key cornerstone for both security and resilience mechanisms, as well as, infrastructure management helping to ensure availability and reliability. Its importance is increasing in the light of Internet-of-Things (IoT) infrastructures growing both in size and complexity, hence, widening the attack surface and decreasing the possibilities of manual management. There is a multitude of different monitoring concepts providing solutions to those problems. However, in the context of IoT those traditional concepts are limited in their adoption capabilities due to fundamental differences in architecture and structure. In this paper, we create a systematization of knowledge about the impact of IoT infrastructure characteristics on requirements for and architecture of monitoring. In particular, we first discuss definitions of monitoring resulting in an own definition, before elaborating on the terminology encompassing monitoring. We further discuss requirements imposed by IoT systems combined with an analysis of monitoring properties relevant for IoT. As part of this paper, we also focus on highlighting current and future directions of IoT architecture and infrastructure.

监控基础设施是安全和弹性机制以及基础设施管理的关键基石，有助于确保可用性和可靠性。鉴于物联网 (IoT) 基础设施的规模和复杂性都在增长，它的重要性正在增加，因此扩大了攻击面并减少了手动管理的可能性。有许多不同的监控概念为这些问题提供了解决方案。然而，在物联网的背景下，由于体系结构和结构的根本差异，这些传统概念的采用能力受到限制。在本文中，我们创建了关于物联网基础设施特征对监控要求和架构的影响的知识系统化。尤其是，在详细阐述包含监控的术语之前，我们首先讨论监控的定义，从而得出自己的定义。我们进一步讨论了物联网系统提出的要求，并结合了对物联网相关监控属性的分析。作为本文的一部分，我们还着重强调物联网架构和基础设施的当前和未来发展方向。
