NMS-3703 is marked as resolved, but annoying tabs in snmp-graph.properties are still in place (both master and 1.8 branch).
Essential description from previous issue:
When using native rrdtool, the Cpu Usage graph is missing. When I switch to jrobin, the graph is present.
The error from 'jetty.log' is:
2010-03-23 13:38:28,390 ERROR [968256266@qtp-258818643-9] log: /opennms/graph/graph.png
org.springframework.dao.DataRetrievalFailureException: Could not create graph: org.opennms.netmgt.rrd.RrdException: ERROR: Could not make sense out of ' '
; nested exception is org.opennms.netmgt.rrd.RrdException: ERROR: Could not make sense out of ' '
When I use the command string from the 'jetty.log' file, it will create the png graph properly.
