###############################################################################
# Log Scanner. This feature will send out an email summary of the log lines of
# each log listed in /etc/csf/csf.logfiles. All lines will be reported unless
# they match a regular expression in /etc/csf/csf.logignore
#
# File globbing is supported for logs listed in /etc/csf/csf.logfiles. However,
# be aware that the more files lfd has to track, the greater the performance
# hit. Note: File globs are only evaluated when lfd is started
#
# Note: lfd builds the report continuously from lines logged after lfd has
# started, so any lines logged when lfd is not running will not be reported
# (e.g. during reboot). If lfd is restarted, then the report will include any
# lines logged during the previous lfd logging period that weren't reported
#
# 1 to enable, 0 to disable
