Stats are one thing, but errors are another.  I've found my best monitor is rsyslog and a perl script.

rsyslog.conf contains:

   local0.* action(type="omprog"
     binary="/usr/local/bin/logMonitor.pl"
     template="RSYSLOG_TraditionalFileFormat")

the perl script is sort of like:

while (<>)
{
     emailme() if (/error/);
}
