I made a change on one of our routers that caused a new ifIndex & name to be assigned to a customer circuit (interface).

Observium is correctly reporting the data on the old virtual i/f (which still technically exists) and – naturally – separately on the new virtual i/f.

Is there any way to (retroactively???) tell Observium that these are really the same interface, and to display only one graph for the two ifIndexes?

Or, if I correct the situation so the old ifIndex & name is being showing traffic again, is there any way to move, or inject, the collected data on the ‘new’ port into the ‘old’ port’s RRDs?  (i.e. avoid a multi-day gap in a multi-year dataset)

We are reasonably up-to-date, running 19.2.9712 – not sure what other info will be helpful here.

Thanks,

-Adam
