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
