NAME

       add_txrx - add two new Data Sources called ’tx’ and ’rx’ to an RRD file

SYNOPSIS

       add_txrx <file> ...

DESCRIPTION

       This utility is used when upgrading from FlowScan-1.005  (or  less)  to
       FlowScan-1.006 (or greater).  It is used to add two new Data Sources to
       FlowScan ".rrd" files. e.g.:

         $ make install # install FlowScan-1.006 in your existing FlowScan dir
         $ cd $prefix/graphs
         $ add_txrx total.rrd *.*.*.*_*.rrd

         tx - a count of the unique source IP addresses
              that have transmitted flows
         rx - a count of the unique destination IP addresses
              that have received flows

       These  Data Sources will allows FlowScan users to calculate the average
       number of bytes, packets, and flows  per  host  and  to  determine  the
       overall level of activity (in terms of numbers of individual hosts) for
       each subnet and for the entire campus.

       The values will be recorded only if you use the TopN directive with the
       CampusIO   and/or   SubNetIO   reports.    TopN   was   introduced   in
       FlowScan-1.006.

       For instance, if you set CampusIO’s TopN to a value greater than  zero,
       the  tx  value in FlowScan’s "total.rrd" is the number of unique source
       IP addresses (hosts) from which FlowScan has seen outbound flows.

       Upgrading your RRD Files

       If you are upgrading, it is necessary to add two new  Data  Sources  to
       the  some  of  your existing RRD files. Before running flowscan, backup
       your RRD files, e.g.:

         $ cd $prefix/graphs
         $ tar cf saved_rrd_files.tar *.rrd

       then do this:

         $ cd $prefix/graphs
         $ ../bin/add_txrx total.rrd [1-9]*.*.*.*_*.rrd
