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
