1. A method for discovering a service dependency chain, the method comprising:
- discovering service dependencies;
identifying a potential service dependency chain based on at least a portion of the service dependencies;
building a number of data paths for the potential service dependency chain;
computing a chain transfer entropy for the potential service dependency chain based on the number of data paths; and
determining whether the potential service dependency chain is the service dependency chain based on the chain transfer entropy.

Abstract
A method and apparatus for discovering a service dependency chain. Service dependencies are discovered. A potential service dependency chain is identified based on at least a portion of the service dependencies. A number of data paths are built for the potential service dependency chain. A chain transfer entropy is computed for the potential service dependency chain based on the number of data paths. A determination is made as to whether the potential service dependency chain is the service dependency chain based on the chain transfer entropy.

13. A method for discovering a service dependency chain, the method comprising:
-
discovering service dependencies; identifying a potential service dependency chain based on at least a portion of the service dependencies; building a number of data paths for the potential service dependency chain, wherein a data path in the number of data paths includes a forward path and a return path that both fall within a path time period; computing a chain transfer entropy for the potential service dependency chain based on the number of data paths; and determining whether the potential service dependency chain is the service dependency chain based on the chain transfer entropy. - View Dependent Claims (14, 15, 16)
