ABSTRACT:
A method of recording diagnostic trace information is disclosed. According to one embodiment, a method is provided in which metadata corresponding to each of a set of events that are subject to tracing is stored, wherein the metadata indicates how useful each of the events is in determining a root cause of a failure. This metadata is used to vary an apportionment of a memory among the events. Diagnostic trace information is then stored within the memory according to the apportionment.
