NAME

rahisto - print histogram of metrics from argus(8) data.

SYNOPSIS

rahisto [ -M histomode ] -H bin[L]:range|size ... [ raoptions ] [ -- filter-expression ]

DESCRIPTION

Rahisto reads argus data from an argus-data source, sorts the records based on the criteria specified on the command line, and outputs a valid argus-stream .

OPTIONS

Rahisto, like all ra based clients, supports a number of ra options including filtering of input argus records through a terminating filter expression. See ra(1) for a complete description of ra options . rahisto(1) specific options are:
-M nozero

Don’t print bins that have zero frequencies.

-M outlayer

Print accumulated stats for outlayer values, i.e. the values that are outside the histogram range.

-M perflow

Generate multiple histograms. One histogram for each -H option will be generated each flow discovered. The flow model is specified with the -m option. See the racluster(1) man page for aggregatable objects. Note that no aggregation takes place as a result of the -m option; this is used only to classify flow records.

-m aggregation object

Supported aggregation objects are listed in the racluster(1) man page.

-H [abs] metric bin[L]:range | size

Specify histogram options, metric, number of bins, whether to use logorithmic scales, and either a range specification to indicate start and stop times, or just the size of each bin. The optional ’abs’ indicates that rahisto should use absolute values for the metric. More than one -H option can be supplied. One histogram per metric will be calculated for the same input data.

Rahisto supports 112 argus metrics, which include most of the metrics

that can be printed. See ra.1 for metric fields that are supported by the ra* programs. The common metrics include:

	dur		record total duration.
	avgdur		record average duration.
	proto		transaction protocol.
	sport		source port number.
	dport		destination port number.
	stos		source TOS byte value.
	dtos		destination TOS byte value.
	sttl		src -> dst TTL value.
	dttl		dst -> src TTL value.
	[s|d]bytes		[src | dst] transaction bytes.
	[s|d]appbytes		[src | dst] application bytes.
	[s|d]pkts		[src | dst] packet count.
	[s|d]meansz		[src | dst] mean packet size.
	[s|d]load		packets per second.
	[s|d]loss		pkts retransmitted or dropped.
	[s|d]ploss		percent pkts retransmitted or dropped.
	[s|d]rate		bits per second.

INVOCATION

A sample invocation of rahisto(1) . This call reads argus(8) data from inputfile and generates a frequency distribution histogram for the transaction duration for HTTP traffic.

A sample invocation where the call reads argus(8) data from inputfile and generates a frequency distribution histogram for the round-trip time of arp volleys in argus(8) data.
