rrdtool                                               RDXPORT(1)



NAME
     rrdxport - Export data in XML format based on data from one
     or several RD

SYNOPSIS
     rrdtool xport [-s--start seconds] [-e--end seconds]
     [-m--maxrows rows] [--step value] [DEF:vname=rrd:ds-
     name:CF] [CDEF:vname=rpn-expression] [XPORT:vname[:legend]

DESCRIPTION
     The xport function's main purpose is to write an XML
     formatted representation of the data stored in one or
     several RDs. It can also extract numerical reports.

     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.

     --enumds
         The generated xml should contain the data values in
         enumerated tags.

     DEF:vname=rrd:ds-name:CF

rrdtool                                               RDXPORT(1)



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

Output format
     The output is enclosed in an xport element and contains two
     blocks. The first block is enclosed by a meta element and
     contains some meta data. The second block is enclosed by a
     data element and contains the data rows.

     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 is (the values will depend
     on the RD characteristics):

       
         1020611700
         300
         1020615600
         14
         2
         

           out bytes
           in and out bits
         
       

     The resulting data section is:
