Which of the following is NOT an event type commonly logged by systems?

In the context of system logging, common event types include Information, Warning, and Error.

Information events provide useful and often necessary details about the routine operation of the system. Warnings indicate potential issues that may not require immediate attention but could escalate if not monitored. Errors signify a failure in the system or a problem that needs immediate addressing to ensure proper functionality.

In contrast, "Insight" is not a standard event type logged by systems. While "insight" might be a term used in data analysis or business intelligence to describe valuable information derived from data, it does not apply to the logging of system events. Thus, it is not part of the typical event logging taxonomy. This is why "Insight" is identified as the correct choice in this question.
