RAHISTO(1) General Commands Manual RAHISTO(1)

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:

Don't print bins that have zero frequencies.
Print accumulated stats for outlayer values, i.e. the values that are outside the histogram range.
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.
Supported aggregation objects are listed in the racluster(1) man page.
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.

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

record total duration.
record average duration.
transaction protocol.
source port number.
destination port number.
source TOS byte value.
destination TOS byte value.
src -> dst TTL value.
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.
