My question is what does the "Backend Limit" of 2200 for both backends represent? I understand that this value is 10% of the 22000 maxxconn on frontend_for_all_sites.
2200
in Backend Limit
é o valor de fullconn
, que é por padrão 10% de maxconn do frontend.
Does this 2200 mean that the maximum amount of connections that the backends will process is 2200 and above that haproxy will return a 503?
Não, a quantidade máxima de conexões é a soma de maxconn
