Re: [syslog-ng] I want to forward Windows server 2008 R2 logs to Linux syslog-ng.

      Hi Jason -

All I am able to provide is this (which is the base that I use in most cases). Obviously the group needs to exist (i.e. "logadmin")

I find this is pretty solid, and the directory structure allows easy searching by date and/or server.

You will need to look up the options for yourself at the Balabit site (they have excellent documentation)

The one thing that I will say is that $HOST and $HOST_FROM differ in that $HOST is parsed from the data in the syslog messages themselves, where $HOST_FROM is the server that sent the packets over the network. I find it more reliable especially when parsing "non-standard" events.

Best of luck,
Jim

destination d_separatedbyhosts {
  file("/data/syslog-ng/$YEAR/$MONTH/$DAY/$HOST_FROM/$HOST_FROM.$FACILITY.$PRIORITY.$YEAR.$MONTH.$DAY");
};

log {
  source(s_local);
  source(s_network);
  destination(d_separatedbyhosts);
};

Hi Jim.
Thank you so much for your reply.
Excuse me, Can you write a config file for me that collect Windows log?

One way to check would be to have syslog-ng use the host macro as
    part of the directory (or file) name and let it create directories
    (or files) for every host it hears from like this:

change create_dirs(yes) 

and create a destination that will use information it parses out of
    the received logs in the filenames:

destination d_separatedbyhosts {
  file( "/var/log/$HOST/$HOST.$FACILITY.$SEVERITY.$YEAR.$MONTH.$DAY"
    );
}

then don't filter at all - just let syslog-ng create at will.

While this may not be what you want eventually, it would let
    syslog-ng create files for any host it hears from, and that might
    show you how the $HOST macro is being parsed.

I have a Windows Box that want to forward all Even logs to my Linux box. I install Snare on Windows(172.30.10.19) and configure it to forward logs to Linux  and my Linux box receive it properly.
