CentOS 7.0 - man page for rrddump (centos section 1)

RRDDUMP(1)				     rrdtool				       RRDDUMP(1)

       rrddump - dump the contents of an RRD to XML format

       rrdtool dump filename.rrd [filename.xml] [--header|-h {none,xsd,dtd}] [--no-header]
       [--daemon address] > filename.xml

       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.

	       The name of the RRD you want to dump.

	       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.

	       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 can not deal with xml headers.

       --daemon address
	       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

       To transfer an RRD between architectures, follow these steps:

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

       2.  Transfer the XML dump to the target system.

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

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

	   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.
