     Abstract:

Modern software systems produce a large quantity of logs, which are valuable runtime data during software operation. In this talk, I will discuss techniques for automatic log management, including log learning, log parsing and anomaly detection, for the purpose of software reliability engineering. Log learning is conducted at the system development time, where we propose a "learning to log" framework to help developers make informed logging decisions during development. The "learning to log" framework is able to automatically learn the common logging practices from existing code repositories and provide actionable suggestions to developers. While systems are under operation, logs will be massively generated and collected.  The collected logs can be viewed as unstructured text, which includes free-text descriptions of system behaviors and parameters of system states. Log parsing is therefore employed to transform the unstructured logs into structured events. Subsequently, anomaly detection techniques can be conducted, which take these structured events as input and construct anomaly detection models. When a sequence of log events occurs, the anomaly detection models can predict whether the corresponding system behavior is anomalous or not. Methodologies in these log management techniques will be introduced, and experimental results will be demonstrated and elaborated in this talk.
