Trace Analysis Patterns (Part 147)

Often, for Inter-Correlational trace and log analysis, we need to make sure that we have synchronized traces. The one version of Unsynchronized Traces analysis pattern is depicted in the following diagram where one trace endsĀ  (possibly Truncated Trace) before the start of another trace and both were traced within one hour:

If tracing was done in different time zones with different local times specified in logs we can determine whether the traces are synchronized (when time zone information is not available in Basic Facts) by looking at minutes as shown for the third trace in the diagram above. This technique can also be used in trace calibration (see Calibrating Trace).

There is a similar analysis pattern for memory analysis called Unsynchronized Dumps.
