Trace Analysis Patterns (Part 169)

Every trace and log has its own set of constants, values that belong to global namespace such as true/false, NULL, Abnormal Values, and common error constants such as “access denied”. Trace Constants may be dependent upon Implementation Discourse. There are also constant values that are local to each trace, for example, user names and IP addresses. They may be constantly repeated in one log but may change for another log. Constants that belong to local namespace may be a part of Vocabulary Index and Basic Facts. Usually Trace Constant is not considered Message Invariant.
