Multiple production logs

So, if each machine’s log is written to a different file, doesn’t it
make it difficult to look through each production.log file when you’re
trying to track down problems? I wonder if there’s a good way to
combine all the log files when you’re debugging.

I’d install splunk (www.splunk.com) and let it co-relate the events
across logs for you. The free version allows up to 500MB of log data
to be indexed per day.

AWStats provides a utility (in the tools directory) called
logresolvemerge.pl

It stitches together multiple log files into time order.
