1. A method comprising:
obtaining, by a device, user experience metrics for a plurality of sessions with an online application;
detecting, by the device, a plurality of anomalies from among the user experience metrics;
determining, by the device and based on a correlation between the plurality of anomalies, that a particular path entity among a plurality of path entities is a root cause of the plurality of anomalies by correlating anomalies across different combinations of the plurality of path entities, wherein the particular path entity comprises an egress service provider or data center of the online application; and
providing, by the device, an indication of the particular path entity being the root cause of the plurality of anomalies.
