Command to display rahisto manual in Linux: $ man 1 rahisto

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.
