Hi In the thread "Rdd graphic spikes" over on -discuss it came to light (I'd never looked) that OpenNMS only supports the GAUGE and COUNTER datasource types in the RRD/JRobin backend.
This is given in the source code for 1.7.5 in source/opennms-services/src/main/java/org/opennms/netmgt/collectd/PersistOperationBuilder.java line 64: /** * RRDTool defined Data Source Types NOTE: "DERIVE" and "ABSOLUTE" not * currently supported. */ static final String DST_GAUGE = "GAUGE"; static final String DST_COUNTER = "COUNTER"; public static final int MAX_DS_NAME_LENGTH = 19; Can I ask why it is that only those two DS types are supported? It doesn't seem like it would require much of a patch (I'll try to knock one together) to support it, but there must be some rationale behind the comment... Thanks!
