MicroSketch: Lightweight and Adaptive Sketch based Performance Issue Detection and Localization in Microservice Systems
In this study, we propose a lightweight and adaptive trace-based anomaly detection and RCA approach, named MicroSketch, which leverages Sketch based features and Robust Random Cut Forest (RRCForest) to rendertrace analysis more effective and efficient.

Graph based Incident Extraction and Diagnosis in Large-Scale Online Systems
This paper proposes a novel system, named GIED, which is a method to automatically analyze the cascading effect of availability issues in online systems. GIED enables the extraction of graph-based issue representations. This representation includes both the issue symptoms and affected service attributes. A neural network is used to perform incident detection. Finally, the PageRank algorithm is used to locate the root cause of the incident.
