+ What is Tailviewer? +

+ +

Tailviewer is a log file viewer for Windows that allows you to view text based log files both offline and in real-time. It is easy to use, incredibly fast and free!

+ +

+ Features +

+ +

Tailviewer can display any text based log file and allows tailing, searching and filtering.

+ +

+ Filtering +

+ +
+

+

Filtering allows you to reduce a log file to only those entries that you're interested in. You can easily chain multiple filters to narrow in on a particular problem.

+

You can filter by sub string (the default), wildcard or using a regular expression. In addition, you can invert filters to hide matching entries.

+

Your filters are stored automatically and available with every log file you open. Tailviewer even remembers which filters were applied the last time you viewed a log file so you don't have to!

+
+ +

+ Multiline filtering +

+

+ Most of the time, log files contain one log entry per line. However that is not always the case, especially when you're logging exception stacktraces or similar + multiline content. For this reason, filters work on log entries, not just lines. That is, if a particular line of a multiline log entry matches the filter, then the + entire log entry is displayed +

+

+ +

+ Unicode support +

+
+

+

Log files shouldn't be limited to plain old ASCII, and neither should you. Tailviewer works with a lot of different encodings including: ASCII, UTF-8 and UTF-16.

+
+ +

+ Multiple log files +

+

You can open multiple log files at the same time and Tailviewer automatically notifies you when an opened log file is modified so you never miss a modification!

+ +

+ Merging log files +

+
+

+

Developing distributed applications is hard. Debugging them is even harder.

+

Tailviewer can help you monitor distributed applications by being able to display a merged view of two or more log files based on the timestamps of individual log entries.

+

You can even display a merged view when its files are being modified.

+
+ +

+ Searching +

+
+

+

Sometimes, you just want to search for the occurence of a string. Tailviewer obviously allows you to easily search a log file and to step through each and every occurence.

+
+ +

+ Level quick filter +

+
+

+

Not interested in debug statements? Can't stand the sight of errors anymore? You can easily select which log levels shall be displayed and which ones should not.

+

Not only does it allow you to hide log entries, but it also gives you an overview over the amount of log entries in a log file. Want to know if a particular file contains any errors? You don't need to search or filter to find the answer!

+
+ +

+ Speed +

+

Tailviewer is incredibly fast and allows you to concentrate on your work, instead of having to wait for the application to respond.
