LogMonitor is a Java-based web application, that allows you to monitor server log files via a web browser. A dynamic, highly configurable AJAX web-interface allows multiple logs to be monitored simultaneously, with on-screen alerts indicating when each one changes. Output can be filtered on the server-side using regular expressions, or at the client-side using a handy JavaScript filter. The Styles dialog allows individual log fields to be hidden from view, or to be highlighted in colour making sure that you can quickly pick out the information that is important to you. LogMonitor behaves much like the UNIX 'tail -f' command, displaying a constantly updating view of the most recent log entries, the number of lines to be displayed can be configured as can the update frequency. LogMonitor is released under the GNU GPL open source licence.
