Re: DNS cache Validation

I wrote a script to expose stats from unbound to SNMP and built a Cacti
template for that. Recently started moving the DNS stats to feed into
Telegraf that pushes to an InfluxDB server, then built a dashboard in
Grafana. We track DNS RTT for a few queries, number of drops, number of
rejects, various record type requests per second, etc. We also have a
Nagios plugin that checks each of our DNS cache resolving servers scattered
across the network to ensure they can resolve a handful of popular domains.

        What are you folk doing to validate your DNS cache server configs
and operation? In other words, what are you doing to make sure they are
performing well, not just alive.
