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.

       % rahisto -H dur 10 -r ~/argus/data/argus*out.gz - port http

       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.
