NAME

rrdtool xport - Export data in XML format based on data from one or several RRD
 

SYNOPSIS

DESCRIPTION

If no XPORT statements are found, there will be no output.

-s|--start seconds (default end-1day)

The time when the exported range should begin. Time in seconds since epoch (1970-01-01) is required. Negative numbers are relative to the current time. By default one day worth of data will be printed. See also AT-STYLE TIME SPECIFICATION section in the rrdfetch documentation for a detailed explanation on how to specify time.

-e|--end seconds (default now)

The time when the exported range should end. Time in seconds since epoch. See also AT-STYLE TIME SPECIFICATION section in the rrdfetch documentation for a detailed explanation of ways to specify time.

-m|--maxrows rows (default 400 rows)

This works like the -w|--width parameter of rrdgraph. In fact it is exactly the same, but the parameter was renamed to describe its purpose in this module. See rrdgraph documentation for details.

--step value (default automatic)

See rrdgraph documentation.

DEF:vname=rrd:ds-name:CF

See rrdgraph documentation.

CDEF:vname=rpn-expression

See rrdgraph documentation.

XPORT:vname::legend

At least one XPORT statement should be present. The values referenced by vname are printed. Optionally add a legend.

Output format

Let's assume that the xport command looks like this:

  rrdtool xport \
          --start now-1h --end now \
          DEF:xx=host-inout.lo.rrd:output:AVERAGE \
          DEF:yy=host-inout.lo.rrd:input:AVERAGE \
          CDEF:aa=xx,yy,+,8,* \
          XPORT:xx:"out bytes" \
          XPORT:aa:"in and out bits"

The resulting meta data section (the values will depend on the RRD characteristics):

  <meta>
    <start>1020611700</start>
    <step>300</step>
    <end>1020615600</end>
    <rows>14</rows>
    <columns>2</columns>
    <legend>
      <entry>out bytes</entry>
      <entry>in and out bits</entry>
    </legend>
  </meta>

The resulting data section:

  <data>
    <row><t>1020611700</t><v>3.4000000000e+00</v><v>5.4400000000e+01</v></row>
