adding new datasource to an existing RRD

rrd, rrdtool

Solution

use rrddump and rrdrestore.

just so:

rrdtool dump my.rrd > file.xml

./rrdAddDS.pl file.xml newDsName > new_file.xml

rrdtool restore new_file.xml my_new.rrd

Problem

I have few 100s of rrds and i want to add 5 extra datasource to all of those rrds. - Is it advisable to do so - Whats the best way and the fastest way to do it -- Soln -- David OBrien replied in the mailing list after searching the archives ( which you should have done first ) and googling I found several people using this... with perl. Install RRD:Simple ``` #!/usr/local/bin/perl use strict; use RRD::Simple (); my $rrd = RRD::Simple->new(); my $rrdfile=$ARGV[0]; my $source=$ARGV[1]; my $type=$ARGV[2]; chomp($type); $rrd->add_source($rrdfile, $source => $type); ``` usage: ``` ./addSource.pl file.rrd ds GAUGE ``` or whatever the type is.. Enjoy.
