Ah, now that seems to be a sensible approach.  :-)

Hi,

in addition to the suggested methods, an alternative way is to grep
system logs for:

 dnsmasq[6620]: setting upstream servers from DBus
 dnsmasq[6620]: using nameserver 192.168.10.1#53(via ens3)

In the next version of NetworkManager (1.6) it will be possible to
show the DNS configuration in the output of 'nmcli' [1], as:

 $ nmcli
 ens3: connected to internet+
"Realtek RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (QEMU Virtual 
Machine)"
ethernet (8139cp), 52:54:00:F1:61:81, hw, mtu 1500
ip4 default
inet4 192.168.10.166/24
 [...]
 DNS configuration:
servers: 10.0.0.1
domains: foobar.com
interface: tun0
type: vpn

servers: 192.168.10.1
interface: ens3

Thanks. That's it.  I somehow missed it there in the manual page:

When it receives a SIGUSR1, dnsmasq writes  statistics
to  the  system log.  … For each upstream server
it  gives  the  number  of  queries sent, and the
number which resulted in an error.
…

That gives me the information I was looking for regarding verifying
which server dnsmasq is using.

Regards,
Lars
