NAME
SubNetIO - a FlowScan module for reporting on campus traffic I/O
by subnet
SYNOPSIS
$ flowscan SubNetIO
or in flowscan.cf:
ReportClasses SubNetIO
DESCRIPTION
SubNetIO is a flowscan report for reporting on flows of traffic
in and out of specific subnets within a site or campus. It is
implemented as a class derived from CampusIO, so you run either
CampusIO or SubNetIO, not both, since SubNetIO inherits all the
functionality of CampusIO. For instance, in your flowscan.cf:
ReportClasses SubNetIO
CONFIGURATION
`SubNetIO''s configuration file is SubNetIO.cf. This
configuration file is located in the directory in which the
flowscan script resides.
The SubNetIO configuration directives include:
SubnetFiles
This directive is required. It is a a comma-seperated list
of files containing the definitions of the subnets on which
you'd like to report. E.g.:
# SubnetFiles our_subnets.boulder
SubnetFiles bin/our_subnets.boulder
OutputDir
This directive is required. It is the directory in which RRD
files will be written. E.g.:
# OutputDir /var/local/flows/graphs
OutputDir graphs
Verbose
This directive is optional. If non-zero, it makes `flowscan'
more verbose with respect to messages and warnings.
Currently the values `1' and `2' are understood, the higher
value causing more messages to be produced. E.g.:
# Verbose (OPTIONAL, non-zero = true)
Verbose 1
TopN
This directive is optional. It's use requires the
`HTML::Table' perl module. `TopN' is the number of entries
to show in the tables that will be generated in HTML top
reports. E.g.:
# TopN (OPTIONAL)
TopN 10
If you'd prefer to see hostnames rather than IP addresses in
your top reports, use the ip2hostname script. E.g.:
$ ip2hostname -I *.*.*.*_*.html
ReportPrefixFormat
This directive is optional. It is used to specify the file
name prefix for the HTML "Top Talkers" reports. You should
use strftime(3) format specifiers in the value, and it may
also specify sub-directories. If not set, the prefix
defaults to the null string, which means that, every five
minutes, subsequent reports will overwrite the previous.
E.g.:
# Preserve one day of HTML reports using the time of day as the dir name:
ReportPrefixFormat html/SubNetIO/%H:%M/
or:
# Preserve one month by using the day of month in the dir name (like sar(1)):
ReportPrefixFormat html/SubNetIO/%d/%H:%M_

VERSION
The version number is the module file RCS revision number
($Revision: 1.27 $) with the minor number printed right
justified with leading zeroes to 3 decimal places. For instance,
RCS revision 1.1 would yield a package version number of 1.001.
This is so that revision 1.10 (which is version 1.010), for
example, will test greater than revision 1.2 (which is version
1.002) when you want to require a minimum version of this
module.
