Why do you need a log viewer?

Log files are often viewed as plain text. A log viewer will parse your log file and read the information. This helps you find, analyze, and fix issues faster.

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.

Multiple Log Sources

LogViewPlus can do more than just read log files. We support other data sources like databases, UDP, Syslog and the Windows Event Log. LogViewPlus is highly extensible and we are committed to helping you view and analyze your logs regardless of the underlying format, protocol or storage method.

Open log files from anywhere.

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.

Open 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). 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.

Extensible API

We work hard to help you get the most from your log files, but nobody knows your log files better than you. That's why we built LogViewPlus to be extensible. The ability to add additional features into the application - like custom filters and parsers - has always been a core part of the application design. Our extensible API will help you execute project specific log file analysis.

Syntax Highlighting

When you look at a block of text, it can sometimes be hard to see the information you need. That's why LogViewPlus supports syntax highlighting on all log entries. Breaking up the text visually helps you process the information faster. LogViewPlus can even pretty-print XML or JSON log entries.

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.

Reporting & Analysis

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 the data is telling you.

Want to go deeper? Full SQL query backed dashboards help you create detailed graphs and statistics 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.

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.
