Log Analyzer is a powerful tool for Graphical Analysis of Log Files, supporting both Log Pattern Analysis and Statistical Analysis of a Log File. We have developed it for our internal use, but we are convinced that it can help many IT professionals in their work, so we are happy to share it: download free Log Analyzer for Windows.

Graphical functionality is an advantage of our product. Many other log reader and log viewer tools only analyze log files in text mode.

Main window of the Log Analyzer shows all log events as a function of time, along with all necessary information such as number of log events in the log file and the time it spans. So, by quick look at the main window, the user can get an instant overview of log events density and their dynamics. With the mouse, any time interval can be zoomed for more detailed view. A separate window can be opened with the classic text view of the log file, where Log Patterns can be easily captured.

Log Analyzer supports both Text and Graphical mode

A log pattern is a combination of start/stop log events and optional occurrence of a value. Log patterns are marked on the graph and value if present is also written there. Log patterns are automatically saved for future use with other files. Statistical analysis of patterns is also supported, and the results are also presented in graphical form.
