What is one of the purposes of a context map in log data?

A context map in log data serves to enhance the understanding of log entries by providing additional context related to those entries. When logging events, simply recording the raw message may not convey enough information about the circumstances under which an event occurred. The context map adds metadata or related information, which can include details such as timestamps, user identifiers, or specific conditions at the time of logging. This enriched context allows for better analysis and troubleshooting when reviewing logs.

The other options, while potentially relevant to logging, do not capture the primary function of a context map. Storing outdated log messages does not provide immediate utility for logging events. Handling log entries with errors is typically managed by error handling mechanisms rather than context maps. Generating reports, while useful, is a distinct function that does not specifically involve the contextual enhancement of individual log entries as provided by the context map.
