A REPEATABLE METHOD
Capture the affected flow, an unaffected control, the impact window and the unknowns before chasing an alarm.
Keep timestamps, counters, measurements and hypotheses separate. Give the next engineer a question they can answer.
Record what recovered, how it was tested and what remains uncertain. An alarm clear is only one observation.
