# NAME

rrddump - dump the contents of an RRD to XML format

# SYNOPSIS

rrdtool dump [--no-header|-n] filename.rrd > filename.xml

or

rrdtool dump [--no-header|-n] filename.rrd filename.xml

# DESCRIPTION

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.

[--no-header|-n]

  In rrdtool 1.3, the dump function started producing correct xml-headers. Unfortunately the rrdtool restore function from the 1.2 series can not handle these headers. With this option you can supress the creatinon of the xml headers.

# EXAMPLES

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.
