       rasplit - split argus(8) data.


       rasplit [[-M splitmode] [splitmode options]] [raoptions] [-- filter-expression]


       Rasplit  reads  argus data from an argus-data source, and splits the resulting output into
       consecutive sections of records based on size, count time,  or  flow  event,  writing  the
       output  into a set of output-files.  By default, rasplit puts 10,000 records of input into
       each argus output file, or standard out.

       The output files' name consists of a prefix, which is specified using the  -w  ra  option,
       and  a  suffix,  which is created for each resulting file.  If no prefix is provided, then
       rasplit will use 'x' as the default prefix.  The suffix that is used is determined by  the
       mode  of  operation.   When  rasplit is using the default count mode or the size mode, the
       suffix is a group of letters 'aa', ´ab´, and so on, such  that  concatenating  the  output
       files in sorted order by file name produces the original input file.  If rasplit will need
       to create more output files than are allowed by the default suffix strategy, more  letters
       will  be  added, in order to accomodate the needed files.  When the mode is time mode, the
       default output filename suffix is '%Y.%m.%d.%h.%m.%s', which  is  used  by  strftime()  to
       create  an  output  filename that is time oriented.  This default is overrided by adding a
       '%' extension to the name provided on the commandline using the -w option.

       When standard out is specified, using -w -, rasplit will output a single argus-stream with
       START  and  STOP  argus  management  records  inserted appropriately to indicate where the
       output is split.  See argus(8) for more information on output stream formats.

       When rasplit is spliting on output record count (the default), the number  of  records  is
       specified  as an ordinal counter, the default is 10,000 records.  When rasplit is spliting
       based on the maximum output file size, the size is specified as bytes.  The scale  of  the
       bytes can be specified by appending 'b', 'k' and 'm' to the number provided.

       When  rasplit is spliting based on time, the time period is specified with the option, and
       can be any period based in seconds (s), minutes (m),  hours  (h),  days  (d),  weeks  (w),
       months  (M)  or years (y).  Rasplit will create and modify records as required to split on
       prescribed time boundaries.  If any record spans a time boundary, the record is split  and
       the  metrics  are adjusted using a uniform distribution model to distribute the statistics
       between the two records.  Care is taken to avoid records with zero packet and byte counts,
       that could result from roundoff error.

       When  rasplit  is  spliting based on flow event, the flow that acts as the event marker is
       specified using a standard ra filter expression, that is bounded by quotes  (").   Records
       that  preceed  the first flow event in the data stream are written to the specified output
       file, and then new files are generated with the flow event record being the  first  record
       of  the  new file.  This method will allow you to use wire events as triggers for spliting


       Rasplit, like all ra based clients, supports a number of ra options including remote  data
       access,  reading  from  multiple  files  and  filtering  of  input argus records through a
       terminating filter expression.  rasplit(1) specific options are:

       -a suffix length
            default is 2 characters.

       -d   Toggle running as a deamon.

       -M splitmode
            Supported spliting modes are:
                count <num>
                 size <size>
                 time <period>
                 flow "filter-expression"

       -w filename
            Rasplit supports an extended -w option that allows for output record contents  to  be
            inserted  into  the  output  filename.   Specified  using  '$' (dollar) notation, any
            printable field can be used.   Care  should  be  taken  to  honor  any  shell  escape
            requirements  when  specifying  on  the  command  line.   See  ra(1)  for the list of
            printable fields.

            Another extended feature, when using time mode, rasplit  will  process  the  supplied
            filename  using  strftime(3),  so that time fields can be inserted into the resulting
            output filename.


       This invocation reads argus(8) data from inputfile and splits  the  argus(8)  data  stream
       based  on output file size of no greater than 1 Megabyte.  The resulting output files have
       a prefix of argus.  and suffix  that  starts  with  'aa'.   The  single  trailing  '.'  is

          rasplit -r inputfile -M size 1m -w argus.

       This  invocation  splits inputfile based on hard 10 minute time boundaries.  The resulting
       output files are created with a prefix of  /archive/%Y/%m/%d/argus.   and  the  suffix  is
       %H.%M.%S.  The values will be supplied based on the time in the record being written out.

          rasplit -r * -M time 10m -w "/archive/%Y/%m/%d/argus.%H.%M.%S"

       This  invocation  splits  inputfile  based  on the argus source identifier.  The resulting
       output files are created with a  prefix  of  /archive/Source  Identifier/argus.   and  the
       default  suffix  starting with  "aa".  The source identifier will be supplied based on the
       contents of the record being exported.

          rasplit -r * -M time 10m -w "/archive/$srcid/argus."

       This invocation splits inputfile based on a flow event marker.  The resulting output files
       are  created  with  a  prefix  of  'outfile.'  and the default suffix starting with  "aa".
       Whenever a ping to a specific host is seen in the stream, a new output file is generated.

          rasplit -r * -M flow "echo and host" -w outfile.
