I want to look at multiple log files and correlate the messages in each based on x minute intervals. This is in an effort to trouble shoot an issue. My initial thoughts are to create a hash with a descriptive name for a log as the key, and then the value being an array with the path to log file and a place to put a reg ex to match the date. (Unfortunately, the logs to not use the same formatting.) Ex: 
$hash{apache_access} = ('/path/to/apache_access.log', 
                         "^\d\d\/\w\w\w\/\d\d\d\d\:\d\d\:\d\d:\d\d");

What i am looking for is an efficient way to coordinate the error messages from different logs in to one data structure and either print that to the screen or dump it to a file. I am worried about the size of the structure, as it could potentially get very large very fast since I will be looking at approximately 7 log files (including switch and firewall logs) for about a 4 hour period on 1 minute intervals. Any suggestions would be much appreciated.
