1. A method for network function virtualization self-healing, comprising:
receiving, at an evaluator engine, key performance indicator (“KPI”) information relating to a virtual network function (“VNF”) in a distributed network;
receiving, at the evaluator engine, a physical fault notification for a physical device in the distributed network;
mapping hardware information associated with the physical device to the KPI information based on the VNF operating on the physical device;
comparing the KPI information against a dynamic threshold that adjusts based on the physical fault information and historical KPI information; and
based on the dynamic threshold comparison, automatically performing a remedial action in the distributed network.
