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:

-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.
-H metric bin[L]:range | size
Supported metrics are:
    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.
