1.7.2                                              2025-03-04                                         RRDDUMP(1)

       The dump function writes the contents of an RRD in human readable (?) XML format to a file or to stdout.
       This format can be read by rrdrestore. Together they allow you to transfer your files from one computer
       architecture to another as well to manipulate the contents of an RRD file in a somewhat more convenient
       manner.

       filename.rrd
               The name of the RRD you want to dump.

       filename.xml
               The (optional) filename that you want to write the XML output to.  If not specified, the XML will
               be printed to stdout.

       --header|-h {none,xsd,dtd}
               By  default RRDtool will add a dtd header to the xml file. Here you can customize this to and xsd
               header or no header at all.

       --no-header|-n
               A shortcut for --header=none.

               If you want to restore the dump with RRDtool 1.2 you should use the --no-header option since  1.2
               cannot deal with xml headers.

       --daemon|-daddress
               Address  of  the  rrdcached  daemon. If specified, a "flush" command is sent to the server before
               reading the RRD files. This allows rrdtool to return fresh data even if the daemon is  configured
               to  cache  values  for  a  long  time.   For a list of accepted formats, see the -l option in the
               rrdcached manual.

                rrdtool dump --daemon unix:/var/run/rrdcached.sock /var/lib/rrd/foo.rrd

       The following environment variables may be used to change the behavior of "rrdtool dump":

       RRDCACHED_ADDRESS
           If this environment variable is set it will have the same effect as specifying the "--daemon"  option
           on the command line. If both are present, the command line argument takes precedence.

       To transfer an RRD between architectures, follow these steps:

       1.  On the same system where the RRD was created, use rrdtooldump to export the data to XML format.

       2.  Transfer the XML dump to the target system.

       3.  Run rrdtoolrestore to create a new RRD from the XML dump. See rrdrestore for details.
