Some informations for the rrd_commix.pl script.
-----------------------------------------------

Description:

The rrd_commix tool comes with two scripts, the rrd_commix.pl and the merged-rrd.py
The merged-rrd.py is for merging single rrd's and the other for mergin NagiosGrapher
directory structures.




This you will need to run:

 - PERL Modules: Getopt::Long, Pod::Usage, File::Basename, XML::Simple, File::Copy
 - Python >= 2.0
 - NagiosGrapher (its provides the directory strucures)



Install:

 - nothing to do, run from a place of you choice ...
 - But keep in mind: the python script have to be located in the same
   directory or you need the '--script' switch.



Example:

 If you want to merge a single rrd database:
 
  merged-rrd.py old_rrd.rrd new_rrd.rrd out_rrd.rrd
 
 That's all.

 For a bunch of NagiosGrapher files:

 ./rrd_commix.pl --old=/var/lib/nagios/rrd_backup --new=/var/lib/nagios/rrd --out=/var/lib/nagios/rrd_test

 The new merged files will be created in the 'out' directory. If the process completed you have to change the rigts
 for the new RRD Location (chmod ...) when you run the script as root. Then you can change the rrd file location in
 the ngraph.cfg for testing purposes to rrd_test. If the test runs successfully rename the merged directory.
