NAME
artsnexthopagg - utility to aggregate nexthop table objects in time
domain
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
particular interfaces or sets of interfaces. ifIndexList may
contain 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
contains 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
(indicating 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
aggregation, 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
artsnexthopagg 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
