Why do you need a log viewer?

Log files are data stores. Most tools that work with log files view data as plain text and cannot help with analysis. A log viewer will parse your log file and transform it into meaningful data. Viewing log files in LogViewPlus will unlock a whole new level of functionality way beyond tail and grep.

Use a text editor to edit text.
Use LogViewPlus to read log files.

LogViewPlus can...

  • Read and analyze large log files
  • Merge multiple log files into a single view
  • Tail remote log files with FTP, SFTP and FTPS
  • Work with text, CSV, XML and JSON
  • Graph log entires by time or category
  • Auto-detect logging formats
  • Transform your log files into meaningful data.


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 Filters

Filtering your 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 applied automatically while tailing the log file. This is similar to how tail and grep work, but completely redesigned for Windows.

Filter Log Files

Open Large Log Files

Large Log Files

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). Opening larger files is constrained only by the amount of memory you have on your machine.

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. Chunk sizes are set at 10 MB, 25 MB, 50 MB and 100 MB so you can decide how much data you need. You can open multiple chunks and consolidate if needed.

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 errors and warnings and allows 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.

You can also set a bookmark and add a few notes. Bookmarks allow you to freely navigate through a log file knowing you can easily return to a particular log entry.

Tail in Windows done right!

Tail Log Files

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 - everything happens automatically. Tail log files in windows like a pro. No command line required.

Tail Log Files From Anywhere

LogViewPlus includes built in native 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.

Tail Remote Log Files

Syntax Highlighting

When you are looking at text, it can sometimes be hard to see the information you need. That's why LogViewPlus supports syntax highlighting on all log entries. LogViewPlus can even pretty-print log entries that contain XML or JSON.

Quick Statistics

Quick Statistics

Have you ever counted the number of errors in a log file?

You are a techie - of course you love statistics. We do too. That's why we put statistics for your log file right on the main window. As soon as you open a log file you can quickly start to get a feel for what it is telling you.

Want to go deeper? Detailed graphs and statistics can be generated for both the entire log file and the current filter. You can view log entry distribution over time or graph data from a particular data column. LogViewPlus is kind of like Excel for log files.

Extensible API

Extensible API

Log files are like snowflakes. They are all unique and beautiful in their own special way. We have put a lot of work into LogViewPlus to help you get the most from your log files, but nobody knows your log files better than you. That is why we built LogViewPlus to be extensible. The ability to build additional features into the application - like custom filters and parsers - has always been a core part of the application design.

Look & Feel

When you spend all day in and out of log files, you want to be using an application that is responsive and looks nice. That's why we put a lot of effort into creating a high performance application with a customizable appearance.
