I went digging with my limited knowledge and found http://issues.opennms.org/browse/NMS-2284, which lead me to createGraph which calls createGraphReturnDetails which again calls createGraphDef, which seems to have issues with the backslashes.

But then, I may just be lost and wrong.

Looks like http://issues.opennms.org/browse/NMS-5106 is also an older duplicate of this one, the issues goes back into 1.9x code.

Yes the same is here in jetty.log

So, any ideas about fix ?
Which deamon or config file can hold the adress parameters ?

Dittoes - Win2003R2 SP2 x32bit here. Same issue, but it also spreads to all the SNMP graphs - none of them work. It looks like a path error not in creating the files but in displaying them. Here is a snip from jetty.log showing the path without some critical backslashes and a print screen showing the files are indeed being created in the correct locations.

The attached print screen shows those files do exist in their proper location, but the path to them is missing some rather important backslashes.

The log shows can't open c:\Program Files\OpenNMS\share\rrd\snmp[missing]1[missing]X0-0017c574d7bc[missing]ifInUnicastpkts.jrb - but those files do indeed exist and are in the correct path.
