Is there a program that can constantly monitor a log file (i.e.
/var/log/messages) and take action in real time when a certain action is
logged?

I know I can run a script that runs every minute as a cron job but I want
something even more responsive than that, like on the order of 3-5
seconds.

You can convince syslog to pipe selected messages to a command.
syslog.conf

Note when piping to `mail`

IF for some reason your ISP calls you screaming MAIL BOMB DOS !!
you might have a fast connection on the server and decided 24 hours earlier
you would like to .forward syslog messages by mail to your private/home ISP.

Changes are your file system is full heheh

I don't really know anything about scripting or programming, but most
languages seem to have a sleep function, and there is /bin/sleep too.
