SYNOPSIS

artsportmagg [-v] [-l topN] [-s portlist] [-i ifIndexList]
             [-I ifIndexList] [-h hours] [-o] [-q]
             outfile infile(s)

DESCRIPTION

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

OPTIONS

-v The -v option causes artsportmagg to print version information and exit immediately.
-s portlist The -s portlist option is used to select a set of ports to be placed in ArtsSelectedPortTable objects in the output file. In other words, instead of writing port matrix objects, we write selected port table objects. A selected port table object does not retain the source to destination port information, but instead lumps traffic into the lower of the source or destination port for ports in portlist and lumps those that aren’t in portlist into the input counters for port 0.

portlist may contain hyphens (indicating an inclusive range) or commas. For example, -s 1-1024,6000,7070 would select ports 1 through 1024 (inclusive), port 6000 and port 7070. All traffic for ports outside of these values would be lumped into counters for port 0.

-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, artsportmagg will write a single port matrix object for the entire time interval seen in infile(s) to outfile.
-l topN The -l topN option may be used to cause artsportmagg to generate selected port table objects based on the amount of traffic (in bytes) for eac port. The top topN ports (by bytes of traffic) will have their own entries in the resulting selected port table objects, and all other ports will be lumped into the entry for port 0.
-o By default, artsportmagg appends to the output file, so you may accumlate aggregate port matrix objects in a single file over multiple invocations of artsportmagg. You may override this behavior with the -o option. This will cause artsportmagg to overwrite the output file instead of appending to it.
-q By default, artsportmagg prints a ’.’ for each port matrix object it reads and prints a ’+’ for each object it writes. You may suppress this behavior with the -q (quiet) option.
