I'm looking into setting up a PowerDNS server to handle a few hundred zones. I'd like to keep track the "usage" of each zone and record, i.e. the number of queries per day to each.
I couldn't find any details in the documentation or in Google on how I might achieve this. I'm unfamiliar with PowerDNS, but thinking a custom PipeBackend is needed? Do PipeBackends replace a standard MySQL backend, in addition to, or only for unresolved queries?
