There's something else you should consider at the same time. There are
many ways that you can setup connection throttling such that the web
server is prevented from being overrun in some of the more obvious ways
that you might not want. There are plugin modules for bandwidth
limiting, but you could also do this with proxy load balancers or even
with some firewalls (e.g. PaloAlto). Depending which way you go, you can
use the triggered notices form the BW limit activation as a key into
your event management system. Then, you know your server isn't
completely overwhelmed yet and you can take action. Otherwise, with
monitoring alone, you're risking knowing about it but not being able to
do anything useful.

I want to know if a web server gets overrun by too much traffic

threads or memory or anything, it will throw errors into the log file,
which are immediately buried.
I can definitely figure this out, but I know I definitely shouldn't.
It's already been done.
I am familiar with zabbix and spiceworks and other monitoring systems.
I'm looking for something more specific than monitoring and alerting -
I'm looking for something that knows how to process the logs of apache
specifically, and mysql, and whatever other services we're using. So
I'm looking for log processing.
Something out there already knows how to process all the log files,
including the apache logs, and tell me the important stuff.
How's it done?
Thanks...
