Thanks a lot for the explanation.
Here the numbers are almost the same as your "s" server because it is the only
server configured in the backend. If there was many, the backend numbers will be around
the sum of the server numbers (for each column).
Although this is a small detail, is there an explanation for the fact
that they are not always exactly equal? Is it the case that they'll
eventually be exactly equal but maybe due to implementation reasons on
how these counters are held in memory there is a slight difference?
thanks

Hello
I have this configuration for a backend containing a server:
backend static_backend
option forwardfor
server s localhost:80 maxconn 900
On the stats page though I see a "Backend" row which shows almost the
same numbers for my "s" server. What does this represent?
The Backend row shows the stats for the whole backend. Here the numbers
are almost the same as your "s" server because it is the only server
configured in the backend. If there was many, the backend numbers will

That "Backend" row shows a limit of 200 (marked with red in the photo

can I change it?
thanks
The Session Limit in the backend row refers to the fullconn parameter of
that backend.
The fullconn is about setting dynamic maxconn on backend servers. You
can read more about it in the docs
http://cbonte.github.io/haproxy-dconv/1.7/configuration.html#4-fullconn
You need to consider the "fullconn" parameter if you have set up
"minconn" in server lines (to use dynamic maxconn), otherwise you can
ignore it.
