Note that the primary problem with Nagios logfile monitoring is
that it can only generate 1 alarm in a given polling interval,
so even though the logfile might indicate multiple problems (cpu
overheat, UPS battery dead, SCSI disk failure) you can only get
one of those thorugh Nagios. Also, the pattern capabilities of
check_log2 are a bit limited for comprehensive syslog
monitoring.
