Set up an additional CDEF.

rrdtool xport
          XPORT:out:"out bytes"
          XPORT:customvar:"Temp" >> /home/temp/abc.xml

Now you'll get a column with '12345' in it next to the outoctets column.

Note that you need the 'out,POP' to make customvar a time series, although you throw away the original 'out' value.  You can't just use 'CDEF:customvar=12345'.

Subject: [rrd-users] Help in RRD XPORT

Hello Everyone,

I am working on a Network Visualization project using RRDTool for my graduate course on Network Engineering.

I want to use the export feature of RRDtool to create an XML where I want to add some hard coded values(DS not in RRD) to the xml.
However, I could not find a solution as of yet.
Please assist me on this.

What I am trying to do -

rrdtool xport \
          DEF:out=if1-inouts.rrd:outoctets:AVERAGE \
          XPORT:out:"out bytes" >> /home/temp/abc.xml
          XPORT:"SOME_CUSTOM_VALUE":"Temp" >> /home/temp/abc.xml

Here I want to append SOME_CUSTOM_VALUE to the output xml, which I am not able to do as SOME_CUSTOM_VALUE is not present in the database.
