The concept of object health is present throughout ACI. When problems are detected, an object’s health score drops from 100, with lower scores indicating greater severity. This is hierarchical, so while a port that is disconnected on a single endpoint will show a health score of 0, the fabric node containing that port may show a health score of 50, and the application containing the down endpoint may show a score of 80.
