In my experience, such things are found in /var/log. On the
HatRed and MandrX systems I have used, I find the following
to be the most interesting:

/var/log/secure (except, always empty on MandrX)
/var/log/dmesg (output of 'dmesg' after the last boot)
/var/log/boot.log (mostly booting-related stuff)
/var/log/messages (a whole bunch of stuff)

The 'dmesg' command is also interesting. Right after boot,
it usually contains the stuff that happened while booting.
Later on, it contains the most recent kernel messages.
Well, it's always the most recent kernel messages, but right
after boot, the only thing there is what happened while
booting.

It is commonly considered a good idea to check these log
files frequently to observe anything problematic, such as
hardware going bad (dma timeouts, I/O errors, etc.),
unauthorized logins (by crackers), malware installation
(also by crackers, etc.), ...
