Trace Analysis Patterns (Part 98)

Some Discontinuities may be Periodic as Silent Messages. If such discontinuities belong to the same Thread of Activity and their Time Deltas are constant we may see Timeout pattern. When timeouts are followed by Error Message we can identify them by back tracing. Timeouts are different from Blackouts where the latter are usually Singleton Events and have large time deltas.

Here is a generalized graphical case study. An error message was identified based on incident Basic Facts:

We filtered the trace for error message TID and found 3 timeouts 30 minutes each:
