Rollbar has a database of well known exception message patterns used by popular libraries and frameworks. Our default grouping algorithm recognizes these exception messages and considers the patterns when computing the fingerprint: e.g. it will group stack traces about timeout errors together regardless of actual wait time and group stack traces about database inserts separately when different constraints are mentioned in the message.
You can find the details of the known exception message patterns for each language and framework below.
