Thanks Adam for checking this.
Basically I created a group which consists of two custom oids:
.1.3.6.1.4.1.2352.2.27.1.2.1.1.1.9.71.76.79.66.65.76.95.97.99
.1.3.6.1.4.1.2352.2.27.1.2.1.1.1.10.71.76.79.66.65.76.95.97.99.50
I'm using them to monitor subscriber interface counters on Redback SmartEdge routers. Unfortunately due to a software limitation I need to use a "one custom oid / vrf" rule to monitor them. I defined both custom oid with the same type and unit.
The graph aggregation works for all the other groups that are not of type custom oid. I'm not sure if the custom oid group graph aggregation is supported or not?
Any update here?
