Access to live limit_conn values?

Server NGINX
1

I’m looking for a way get the value of the current number of connections
in
a given limit_conn zone.There is no variable access that I can find.

I’m considering hacking this into the stub_status module, so that all of
the
active connection zones are displayed with the current number of active
connections.

Is this value accessible via the lua or perl interface?

Having a way to just add this value to the log line might be sufficient.

Our own investigation indicates that, no, there is not way to directly
access the values in the limit_conn zones from “user space.”

We created a new status page that reports all the existing zones and the
current connection counts for each, as well as what the current limits
are.
It does this by walking the config data structure and building a list of
the
zones and then creating a simple report page.
