There is a workaround you can use. Choose a node, say node 1 (I usually use the node for OpenNMS itself), then make symbolic links: /opt/opennms/share/rrd/snmp/1: ln -s ../x/item.jrb ./itemforx.jrb ln -s ../y/item.jrb ./itemfory.jrb ln -s ../z/item.jrb ./itemforz.jrb Then create your report in snmp-graph.properties and use itemforx, itemfory and itemfox in the "columns" section. Then you can sum them together. -T _______________________________________________________________________ Tarus Balog, OpenNMS Maintainer Main: +1 919 533 0160 The OpenNMS Group, Inc.
