The problem

I've been noticing that my Fallback DNS target is being used on occasion. However, from the dashboard, Top Upstreams shows the count each Upstream DNS is being used. But there's no way to drill deeper to figure out what client(s) or what DNS lookups are being handled by it.

Also, from the Query Log, there's no way to filter based on the Upstream DNS server used. The only way to see that information is to hover your mouse over the 'info' icon (circle with question mark in it). Searching for the Upstream DNS server returns no matches.

Proposed solution

Allow drilling down from the Top Upstreams on the dashboard to show what clients and/or lookups are being handled by the specific Upstream DNS server. This would be similar in functionality to the 'Top Queried Domains', 'Top Blocked Domains' or 'Top Client' dashboard widgets.

For the Query Log, allow for searching the Upstream DNS server(s), or add the option to the 'Queries' drop-down.
