NAME

       welf2dlf - convert firewall logs in WebTrends Enhanced Log Format to DLF

SYNOPSIS

       welf2dlf file

DESCRIPTION

       welf2dlf converts firewall logs in the WebTrends Enhanced Log Format into the firewall DLF.

       That format is defined at the following URL: http://www.netiq.com/partners/technology/welf.asp

       This converter also supports the SonicWall extensions.

       A list of firewall products that supports that format can be found at the following URL: http://www.netiq.com/products/fwr/compatible.asp

IMPLEMENTATION NOTES

       Since the firewall DLF only supports packet filters, not all records will be mapped to DLF.

       Dropped packets messages (those with a field msg="XXX packet dropped") will be mapped to denied DLF packet. (As well as all msg="TCP
       connection dropped" records). Those packets will have a length of 0 (that's a limitation of the format which don't log that information on
       dropped packet).

       Messages with a proto= field set will be interpretted as "permitted" "packet". That's not exactly "right" because this message really
       represent a "packets flow" and not a single packet.

       Other records will be ignored.

       You may use the welf_proxy service in the proxy superservice to extract proxy level information from WELF logs.

EXAMPLES

       To process a log as produced by WebTrends:

	$ welf2dlf < welf.log

       welf2dlf will be rarely used on its own, but is more likely called by lr_log2report:

	$ lr_log2report welf < /var/log/welf.log

THANKS

       Mark D. Nagel, for giving feedback and supplying patches.

NAME

       Lire::Last - Lire class that implements the last operator

SYNOPSIS

	use Lire::Last

DESCRIPTION

       Class that implements the last operator. This operator will output the last value appearing in its field when the DLF records are sorted
       according to the "sort_fields" attribute. The default sort order is the default timestamp sort.

METHODS

   new( %params )
       Creates a new Lire::Last object.

   sort_fields( [$new_sort_fields] )
       Returns the fields that are going to be used to sort the DLF records.  This a reference to an array of DLF field names.

       If the $new_sort_fields parameter is set, it will be used as the new sort order. It must be an array reference and should only contains
       valid field names for the current report specification's schema.

       When no sort_fields are set, the default is to use the default timestamp field. =cut
