A customer of ours was having some serious disruptions to his webserver, with 15 minute outages happening here and there. He said he couldn’t see an increase in traffic and therefore didn’t understand why it reached maxclients. Here was a quick way to prove whether traffic really increased or not by directly grepping the access logs for the time and day in question and using wc -l to count them, and a for loop to step thru the minutes of the hour in between the events.
Proud of this simple one.. much simpler than a lot of other scripts that do the same thing I’ve seen out there!
