Trace Analysis Patterns (Part 71)

Sometimes we need to analyse Last Activity before Significant Event or Discontinuity. By this pattern we mean a loose semantic collection of messages before process exit, for example. This might give some clues to further troubleshooting. In one incident a process was suddenly exiting. Its own detailed trace didn’t have any messages explaining that probably due to insufficient tracing coverage (Sparse Trace). Fortunately, a different external trace (from Process Monitor) was collected (Inter-Correlation) and it had LDAP network communication messages just before thread and process exit events.
