Hi. On The Dude 4.0Beta3, I had a data source with this code (to chart bandwidth of a queue tree queue on a CCR):

rate(diff64(oid("1.3.6.1.4.1.14988.1.1.2.2.1.7.16777218")))*8

I'm testing The Dude 6.36rc30 and this function isn't working. The result of the query is always just 0. I did verify that SNMP was working for the device I'm polling. If I remove the "diff64" portion of the function, it gets data, but of course it's not the delta between the two polls. Do I need to change the string because of a change in The Dude?
