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
