LogFusion is a powerful log monitoring tool designed to allow for easy parsing of logs, including web server logs, developer debug logs and pretty much any other text that's outputted to a file.
LogFusion's Row Highlighting and Text Filtering features will permit a quick filter of your log and only show the relevant lines. You will also have the Custom Columns feature to parse and split your logs into separate columns for easier reading. Just like the popular 'Tail' program in Linux/Unix, LogFusion can also auto-scroll and always show you the newest lines in your log files in real-time.
