[Snort-users] Output plugins -differences between loggingmethods?

Whilst we have had far too many questions that could have been answered by
RTFM recently, I do not believe this is one of them.

Read his original question carefully, the re-read that section of the FAQ
you quoted - it doesn't answer it.

He is asking "since both LOG and ALERT appear to be producing the same
output, why should I use both of them? Except, if I only use LOG then I will
miss port scans....but if I only use ALERT, will I get full packet
contents....? etc, etc, etc"

A common question in my experience but not one I feel qualified to answer

Taken from
Furthermore, there is a logging method and database type that must be
defined. There are two logging types available, log and alert. Setting
the type to log attaches the database logging functionality to the log
facility within the program. If you set the type to log, the plugin will
be called on the log output chain. Setting the type to alert attaches
the plugin to the alert output chain within the program.

Please see the documentation & FAQ on http://www.snort.org. They are
pretty well written & you should find answers to a lot of questions that
you may have before posting to this list. A good idea will be also to
search the archives at:
