NAME
       artsnexthopagg -	utility	to aggregate nexthop table objects in time do-
       main

SYNOPSIS
       artsnexthopagg [-v] [-i ifIndexList] [-I	ifIndexList]
		      [-h hours] [-o] [-q] outfile infile(s)

DESCRIPTION
       artsnexthopagg is a utility that	reads nexthop table objects from  ARTS
       files  (infile(s))  and aggregates them in the time domain, placing the
       resulting nexthop table object(s) into an output	file (outfile).

OPTIONS
       -v     The -v option causes artsnexthopagg to print version information
	      and exit immediately.

       -i ifIndexList
	      The  -i ifIndexList option may be	used to	select only data which
	      contains an interface index attribute in ifIndexList.  In	 other
	      words,  the -i ifIndexList option	lets you select	data from par-
	      ticular interfaces or sets of interfaces.	 ifIndexList may  con-
	      tain  hyphens  (indicating  an inclusive range) and commas.  For
	      example, -i 1,2,5-8 would	select data with  an  interface	 index
	      attribute	of 1, 2, 5, 6, 7 or 8.

       -I ifIndexList
	      The -I ifIndexList option	may be used to combine data which con-
	      tains an interface index attribute  in  ifIndexList.   In	 other
	      words,  the -I ifIndexList option	lets you aggregate data	across
	      a	set of interfaces.  ifIndexList	may contain hyphens  (indicat-
	      ing  an  inclusive  range)  and commas.  For example, -I 1,2,5-8
	      would combine all	data with an interface index attribute	of  1,
	      2,  5,  6, 7 or 8.  The resulting	aggregate objects will contain
	      an interface index attribute of 0.

       -h hours
	      The -h hours option may be used to specify the period of	aggre-
	      gation, in hours.	 The hours argument accepts a decimal value to
	      permit aggregation by fractional hour values.  When the -h hours
	      option  is  not used, artsnexthopagg will	write a	single nexthop
	      table object for the entire time interval	seen in	 infile(s)  to
	      outfile.

       -o     By  default,  artsnexthopagg  appends to the output file,	so you
	      may accumlate aggregate nexthop table objects in a  single  file
	      over  multiple  invocations of artsnexthopagg.  You may override
	      this behavior with the -o	 option.   This	 will  cause  artsnex-
	      thopagg to overwrite the output file instead of appending	to it.

       -q     By  default,  artsnexthopagg prints a '.'	for each nexthop table
	      object it	reads and prints a '+' for each	object it writes.  You
	      may suppress this	behavior with the -q (quiet) option.

EXAMPLES
       artsnexthopagg -h 1.0 /tmp/nexthop1hr.19980821 arts.19980821
