搜索完档案(您应该先完成此操作)并进行谷歌搜索之后，我发现有几个人正在使用此文件...

after searching the archives ( which you should have done first ) and googling I found several people using this...

带有perl.安装RRD:Simple

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); 

用法:

./addSource.pl file.rrd ds GAUGE 

或任何类型.

享受.

推荐答案

如果您使用的是PNP4Nagios( https://docs.pnp4nagios.org/pnp-0.6/start )，它们提供了实用程序脚本 rrd_modify.pl ，用于修改现有的RRD数据文件.

If you're using PNP4Nagios (https://docs.pnp4nagios.org/pnp-0.6/start), they provide a utility script rrd_modify.pl for modifying existing RRD data files.

    $ 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)
