Trace Analysis Patterns (Part 59)

Sometimes we don’t see anything in the trace or see very little because particular source code fragment was not covered by trace statements (see also PLOTs):

We call this pattern Sparse Trace and this is different from Missing Component pattern where some modules were not included for tracing explicitly although there is tracing code there or Visibility Limit pattern where tracing is intrinsically impossible. Often technical support and escalation engineers request to add more trace statements and software engineers extend tracing coverage iteratively as needed.
