LogViewer

LogViewer is a lightweight application you can use to analyze log details from files and monitored TCP ports. It features customizable presets and uses regular expressions to personalize some aspects of log lines.

The program is packed in a single executable file that can be saved anywhere on the disk or copied to a USB flash drive to run it on any computer directly.

It doesn't modify system registry settings or create files on the disk without your consent. On the other hand, you should make sure to have .NET Framework installed, since it cannot work without this software framework.

As far as the interface goes, LogViewer doesn't highlight graphical elements, preferring to focus on options instead. These become available by accessing the right-click menu.

Text documents can be loaded from LOG-formatted files using the built-in folder navigator to inspect each line of code, including date and timestamps, as well as any warnings or errors.

To listen to a TCP socket, you just have to specify the port number. Any transferred messages shall be displayed in the main window. Word wrapping is possible, so you don't have to enlarge the window to get a view of the full text if the lines are long.

You can increase or decrease the font size, select the character encoding mode (ASCII, Unicode, UTF-7, UTF-8, Big Endian Unicode) and store selected lines to the Clipboard.

Presets for files or TCP ports can be put together and saved as XML files by setting patterns to clean, hide and colorize lines, specifying the buffer size, skipping empty lines, and wrapping words.

The interface of LogViewer looks rudimentary but has a neatly structured layout that makes it easy to navigate. However, some experience is necessary to write patterns as regular expressions to generate and save presets. CPU and memory usage was minimal in our tests.
