US Patent 9699043 Policy service logging using graph structures

A policy service logging system includes one or more servers connected by a network. The one or more servers are configured to provide a graph structure having a plurality of nodes. Each node is in communication with at least one other node. The graph structure is configured to process log entries of network resource requests subject to policy implemented by a policy service. As log entries flow through the graph structure, the nodes perform operations on the log entries.
