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.

LogViewPlus can quickly process large amounts of log file data. (1:20)

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 provide your analysis with more data, or give you insight into how multiple processes interact.

Quick Data Filters

Filtering log files is better than searching because filters can be combined into a more detailed query. For example, you can narrow your log file down to a particular thread and then search just within that thread. Filter results can also be joined using AND OR relationships or excluded to show everything that does not match. LogViewPlus is like tail, grep, and awk combined and 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 Large Datasets

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. All features in LogViewPlus are built with tail in mind, so when a new update happens, filters and statistics update automatically.

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. Now you can read and tail all of your log files in Windows without starting a telnet session. It may sound small, but when you do it every day this feature can really add up to save you a lot of time. If you find an issue and need to jump on the box, we make that easy too by working with third party tools such as PuTTY.
