LogObserver is a version of the Unix tail tool which runs on Windows. 

Using LogObserver you can

• monitor log files.
• search in monitored log files.
• highlight lines that include certain keywords.
• open log files using drag&drop or command line.
• continue monitoring log files after a log file rollover.
  During a log file rollover the log file will be closed, removed or renamed and newly created. Some tail ports fails on that.

System requirements:

• Microsoft Windows 2000/XP/2003
  Please note, that Microsoft Windows 95/98/Me are not supported!
• Pentium II 200 MHz and higher
• 2 MB hard disk space
