Real-time programs and systems generate various events that users may not have time to react to, as they can end quickly or go unnoticed. To address this, a log function is added to record all events in parallel with on-screen display, providing a record of events, their timings, and order.

Log files provide invaluable opportunities for analyzing the factors that cause specific actions. They allow restoration of the entire sequence of events, making it possible for users to understand what went wrong, why it happened, and how to prevent similar issues in the future.

For systems that measure different parameters, such as temperature, pressure, and voltage, log files can save corresponding values and track changes in dynamics. These values can be analyzed manually or with mathematical packages for better understanding of the system's behavior under different conditions.

Log files can also be used for graphical representation of data changes in graphs and diagrams. Multiple logs can be compared and overlaid to track patterns and make comparisons.

Log files are ordinary text documents that receive records at specific intervals. Each record contains both data and a timestamp, and they are added at a certain frequency or only when a particular event occurs.

Storing log files typically does not require significant resources, but systems with high sensor polling frequencies may lead to large log sizes. For systems that work continuously and write significant amounts of data, it is necessary to consider storing large amounts of text information or saving them to an external source.

For systems that run for long periods without human intervention, it is essential to have tools for maintaining log files and their subsequent processing.
