Abstract
A computer system receives a set of messages, and processes the messages using a filter. In some examples, the filter is defined using a pattern matching language such as a regular expression. The system collects a set of representative messages that match the filter. Using the set of representative messages, the system generates a corresponding flow network graph. Using the flow network graph, the system determines a similarity measure that indicates whether a new message resembles other matching messages of the filter. Based on the similarity measure, in various embodiments, the system identifies potential errors in the filter definitions, omissions in the terms of the filter, and message outliers that indicate system anomalies or events of particular interest to the user.
