NAME

artsnetagg - utility to aggregate net matrix objects in time domain

SYNOPSIS

artsnetagg [-v] [-i ifIndexList] [-I ifIndexList]


           [-h hours] [-o] [-q] outfile infile(s)

DESCRIPTION

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

OPTIONS

-v

The -v option causes artsnetagg 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, artsnetagg will write a single net matrix object for the entire time interval seen in infile(s) to outfile.

-o

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

-q

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

EXAMPLES

artsnetagg -h 1.0 /tmp/netagg1hr.19980821 arts.19980821
