P-DRA Metadata-Generating Events

The metadata captured by IDIH for the Policy DRA application includes the results of each query that Policy DRA makes to the session and binding database and the associated result. Whenever the result of a database query is captured in Policy DRA metadata, it will include the identity of the specific server that generated the response.
