Ok, all looks good so far, directory is created, rrd is written.
date of jrb-File is frequently updated, collectd.log says:

2008-05-02 17:06:19,157 INFO [CollectdScheduler-50 Pool-fiber37] RrdUtils: updateRRD: updating RRD file /opt/opennms/share/rrd/snmp/209/partner-dev/oepcurrcncnt.jrb with values '1209740779:2'

But in the resource graph page for node 209, service partner-dev is listed under SNMP Interface data
with remark "(Not currently updated)". Same for xml-Export from jrb-file.
