Modern microservice systems have gained widespread adoption due to their high scalability, flexibility, and extensibility. However, the characteristics of independent deployment, decentralization, and frequent dynamic interactions also introduce the risk of cascading failures, making it challenging to achieve accurate failure diagnosis and rapid system recovery. These issues severely impact operation efficiency and user experience. Recognizing the crucial role of failure diagnosis in enhancing the stability and reliability of microservice systems, researchers have conducted extensive studies and achieved a series of significant outcomes. This survey provides a comprehensive review and primary analysis of 94 papers from 2003 to the present, including an overview of the fundamental concepts, a research framework, and problem statements. These insights aim to help researchers understand the latest research progress in failure diagnosis. Publicly available datasets, toolkits, and evaluation metrics are also compiled to assist practitioners in selecting and validating various techniques, providing a foundation to advance the domain beyond current practices.
