Actually it's oversimplified. There is no such thing as disconnect in
nanomsg. It may be endpoint which has no underlying transports. But if
DNS SRV is implemented right, that thing is even more subtle.
Also admins do not look at the graphs in the first place. They get
SMSes or Emails when monitoring system get's error. And only if it's
not clear from monitoring data what's wrong, the graphs are helpful.
So the statistical data is a primary thing to implement. And then
graphs, on top of it.

So do you thing the DNS database alone is enough to build the graph?
(except actual connection counts of course)
