1. A method, comprising:
determining, by a device, a plurality of routes from one or more sources in a localized network domain to external addresses via a plurality of border leaf nodes of the localized network domain, wherein each of the plurality of border leaf nodes connects the localized network domain to an external network;
selecting, by the device and based on a specific performance test from a particular source of the one or more sources to a particular endpoint with a corresponding external address, a particular border leaf node of the plurality of border leaf nodes that is along a utilized route from the particular source to the particular endpoint based on the corresponding external address and the plurality of routes;
causing, by the device, the specific performance test to be executed from a particular testing agent installed on the particular border leaf node to the particular endpoint;
stitching, by the device and into end-to-end path metrics, performance metrics of the localized network domain from the particular source to the particular border leaf node to results of the specific performance test from the particular testing agent installed on the particular border leaf node to the particular endpoint; and
correlating, by the device, the end-to-end path metrics to the particular source as a result of the specific performance test from the particular source to the particular endpoint.
