A planned upgrade window opens and correlation stops working, so operations sees thousands of uncorrelated alarms. What is wrong with your inventory and change data?

Answer

Short answer

Correlation is a traversal of the inventory graph, and an upgrade changes exactly the part being traversed. Model planned as well as as-built state, carry the set of resources a change touches as data, scope suppression to that set rather than to the time window, and confirm recovery positively.
