I do not know!
I need values of custom vars and sugest my personal solution :

install onecontext from https://github.com/OpenNebula/addon-context-linux

and put your interesting information:

#old style
#echo “curl -k -X “PUT” $ONEGATE_ENDPOINT/vm --header “X-ONEGATE-TOKEN: $TOKENTXT” --header “X-ONEGATE-VMID: $VMID” --data-binary @$TMP_DIR/metrics”

#new style
echo "onegate vm update $VMID --data cat $TMP_DIR/metrics"

The XML-RPC call is one.vm.info. You’ll get an xml with all the VM information in XML form. To get a example of this XML data you can use the command:

$ onevm show -x <vmid>
