WebSphere question

Does anybody know about an app that does log file analysis of the Application Server’s stdout.log file? The other analysis programs I’ve tried only work with Webserver log files, and the Log Analyzer that ships with WebSphere just lists all the contents of the file, highlighted according to severity of issue.

I’m looking for something that would allow me to track issues through the log files, show trends, elapsed time, and other things normally reported by applications such as WebTrends.
