Instrumentation and monitoring of service level agreement (SLA) and service policy enforcement

Source policy identification information of a registry service policy is correlated with configured policy enforcement processing rules and processing actions using a source policy reference key. The source policy identification information includes at least a source policy identifier (ID) of the registry service policy. Per-transaction service policy enforcement information that documents policy enforcement activities performed by a policy enforcement point (PEP) is correlated with the source policy identification information using the source policy reference key. The correlated per-transaction service policy enforcement information of at least one transaction from the per-transaction service data table is provided in response to a query from a policy monitoring point (PMP).
