​Hi,

I
​don't
see all mailling, but this I know how to do.

​You can have a daemon, that grab statistics each second

​1 - Using ​'system' ​unbound-control stats_noreset
2 -​ ​Or your own daemon, connecting via TCP+SSL, and making the command.

Each reply has a connection close, so you need to reconnect.

This 2, for me, isn't the best way, because the CPU increase.

3 -​ ​Or, use the Shared Memory, so you can create a daemon and attach to
SHM and get
needed​​ info.

After getting the info, you need to populate some files or database.
With that info, you can create graphs.

Use your imagination and the data needed.

Here are some screenshots from one of our client, to show the ideia.
