Highlighter is a free utility ... with three views of the log or text file being analyzed:
- a text view that allows users to highlight interesting keywords and remove lines with “known good” content
- a graphical, full-content view that shows all content and the full structure of the file, rendered as an image that is dynamically editable through the user interface
- a histogram view that displays patterns in the file over time. Usage patterns become visually apparent and provide the examiner with useful metadata that is not available in other text viewers/editors.
