用Perl。安装RRD：简单

#!/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);

用法：

./addSource.pl file.rrd ds GAUGE

或任何类型..

请享用。

Answer 1:

使用rrddump和rrdrestore。

只是这样：

rrdtool dump my.rrd > file.xml

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

rrdtool restore new_file.xml my_new.rrd

Answer 2:

如果您使用PNP4Nagios（ https://docs.pnp4nagios.org/pnp-0.6/start ），它们提供了修改现有RRD数据文件的实用程序脚本rrd_modify.pl。

    $ rrd_modify.pl -h

   === rrd_modify.pl 0.01 ===
   Copyright (c) 2012 PNP4Nagios Developer Team (http://www.pnp4nagios.org)

   This script can be used to alter the number of data sources of an RRD file.

   Usage:
   rrd_modify.pl RRD_file insert|delete start_ds[,no_of_cols] [type]

   Arguments:
   RRD_file
      the location of the RRD file. It will NOT be overwritten but appended
      by ".chg"
   insert or delete
      the operation to be executed
   start_ds
      the position at which the operation starts (1..no of data sources+1)
   no_of_cols
      (an optional) number of columns which will be added/deleted
   type
      the data type (one of GAUGE, COUNTER)
                Defaults to GAUGE if not specified for insert operations
        (DERIVE, ABSOLUTE, COMPUTE have not been tested and might result in
                 errors during creation of a new RRD file)
