It displays a 'Partial Report' where repetitive log messages (like update versions and errors) are grouped with their occurrence count (e.g., [74961] repetitions). At the bottom, it highlights the tool's high efficiency, showing a memory footprint of less than 1MB while processing large volumes of data.](https://img.alternativeto.net/s/309x197/jpeg/goxe_881513_full.png)
