This is for those of us who still have distributed logging. I worked in an environment where this was the case and so I wrote this script to merge the logs in a chronological order so that I could follow the flow of some actions when the load balancer decided to kick in.

eg:

• pull the log files from all of your servers into one folder, say /home/mobile_freak/logs/
• say for the sake of this example my log files from each server are named log1~5
• have a file in that folder, call it sources, which contains the exact paths to all of the log files in separate lines.
• The command would be:

$> ruby merge_logs -s /home/mobile_freak/logs/sources -d /home/mobile_freak/logs/merged_logs
