Method and apparatus for predicting experience degradation events in microservice-based applications

A system, comprising:

• a non-transitory memory comprising computer-readable instructions;
• and
• a processor configured to execute the computer-readable instructions and cause the system to:
• receive log data associated with a plurality of nodes comprising microservices of a microservice-based application, wherein the plurality of nodes form a plurality of directed acyclic graph (DAG) paths;
• derive a plurality of quality of service (QOS) metrics for each node of the plurality of nodes based on the log data, wherein the plurality of QOS metrics are associated with a plurality of QOS levels indicating whether an experience degradation event will occur;
• predict, using a machine learning model, a QOS level for at least one node of the plurality of nodes indicating that an experience degradation event will occur based on the plurality of QOS metrics, wherein the experience degradation event is expected to occur during operation of the microservice-based application;
• and
• perform an action to avoid the experience degradation event based on the predicted QOS level.

• predicting an aspect associated with the experience degradation event based on the QOS level for the at least one node and one of a hierarchy of the plurality of nodes or a DAG path of the plurality of DAG paths comprising the at least one node;
• and
• performing an action to avoid the experience degradation event based on the aspect.
