“…Overall, a log entry is produced by a log printing statement in a system program's source code. Techniques have been developed to relieve this manual work and to take advantage of the rich information present in logs in an automated manner, such as process mining [8], [12], [25], anomaly detection [6], [10], [11], [28], [27], fault localisation [26], [32], invariant inference [7], performance diagnosis [15], [20], [22], [31], online trace checking [5], and behaviour analysis [21], [29].…”
