Anomaly detection in time series is a broad field with many application areas, and has been researched for many years. In recent years the need for monitoring and DevOps has increased, partly due to the increased usage of microservice infrastructures. Applying time series anomaly detection to the metrics emitted by these microservices can yield new insights into the system health and could enable detecting anomalous conditions before they are escalated into a full incident. This thesis investigates how two proposed anomaly detectors, one based on the RPCA algorithm and the other on the HTM neural network, perform on metrics emitted by a microservice infrastructure, with the goal of enhancing the infrastructure monitoring. The detectors are ...
