# Log Scanner

The log scanner 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`. Be aware that the more files LFD has to track, the greater the performance hit.
> > > > > • File globs are only evaluated when LFD is started.
> > > > > • 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.
