Query information logging fills a void for ABL developers trying to evaluate what happens when a query executes and how efficient query execution might be. In large deployed applications, it is impractical for developers to add diagnostics to their code to track and analyze the efficiency and performance of queries.
Query information logging takes advantage of the OpenEdge logging infrastructure to provide you with extended logging information that helps you to locate and correct issues with queries that cause performance degradation (such as poorly indexed queries, or client/server queries that result in excess network traffic).
The following sections provide information about using query information logging.
