Why Is the Number of Active Connections Monitored by Cloud Eye Different from the Number of Connections Established with the Backend Servers?

The number of active connections collected by Cloud Eye refers to the number of active connections between clients and the load balancer.

For a TCP or UDP listener, the load balancer transparently transmits client requests. The number of active connections is equal to the number of connections that the load balancer establishes with backend servers.

For an HTTP or HTTPS listener, the clients connect to the load balancer, which then connects to backend servers. The number of active connections is not related to the number of connections established with backend servers.
