Open large log files with ease.

LogViewPlus can open and analyze gigabytes of log file data in a few seconds. It's built for large data sets that would exceed the limits of most text editors.

Large log files can be difficult to work with and tail is not enough. Most text editors will crash if you try to open a log file greater than about 500 MB, but LogViewPlus was designed from the ground up with large log files in mind. With LogViewPlus, your ability to open large log files is constrained only by the amount of system memory you have available.

Open Part of a Log File

Struggling with 4GB log files in notepad? LogViewPlus loves large log files and can open a 500 MB log file in about 30 seconds (depending on your hardware). But LogViewPlus can also do something a bit smarter. It can divide the file into chunks and let you decide which chunk you are interested in. You can even open multiple chunks and then merge your logs as needed.

Merge Log Files

With LogViewPlus, you can open as many log files as you need and press a button to combine them. Merged log file entries are automatically sorted by date so the information appears to be written by a single process. Merging log files can give you greater insight into how multiple processes are interacting with each other.

Quick Data Filters

Filtering log files is better than searching because filters can be chained. For example, you can narrow your log file down to a particular thread and then search just within that thread. Filters can also be updated automatically while tailing the log file. This is similar to tail and grep, but completely redesigned for Windows.

Easy Navigation

LogViewPlus has several features to help you quickly find what you are looking for, including a Navigation Bar on the far right of the application which shows bookmarks, errors and warnings. The navigation bar facilitates easy one-click scrolling.

There are also navigation options when filtering. For example, you can double-click a log entry and go to the root log file. All navigation options maintain the currently selected row, so you can stay focused on what is important.

Tail in Windows done right!

LogViewPlus processes real-time log file updates through functionality similar to the Unix 'tail' command which tracks log entries as they are written to the log file. This means you immediately see the new log entries in your log viewer. No need to mess around with a refresh button. Tail log files in windows like a pro. No command line required.

Tail Log Files from Anywhere

LogViewPlus includes built in support for technologies like SFTP, FTP, SCP, and SSL as well as mapped drives and Samba shares. Because the world is full of networks and often the log files you need do not exist on your local machine. Now you can read and tail all of your log files in Windows without starting a telnet session.
