Hi all, I have some trouble with one of cacti graph which return nan value all the time.
I am using cisco switch 6504e and want to get the usage of tunnel 30 interface.
'SNMP - Interface Statistics' data query work find of other interface, only this interface show nan.
When I tried to use snmpwalk and grep the oid from cacti log. Both of them can return the correct value.
But when I rrdtool fetch command, It only show -nan in all timeline.
I am using the 'In/Out Bits (64-bit Counters)' template. Any help will be greatly appreciated. Thanks.

More information:
