How Do I Check If There Is Excessive Access Delay?

  1. Bind an EIP to a backend server to make the applications accessible from the Internet and then check the access delay. In this way, you can determine whether the problem is caused by the client, load balancer, or applications.
  2. Check the incoming traffic. If the incoming traffic exceeds the EIP bandwidth, there may be congestion and packet loss.

    If the incoming traffic exceeds the available bandwidth, it does not mean that the bandwidth is fully used. In this case, you need perform further operations to locate the fault or increase the bandwidth.

  3. Check the load and security policies of backend servers. If backend servers are heavily loaded or they have security policies configured, they cannot quickly respond to requests from the associated load balancer.
  4. Check the health of backend servers based on the Unhealthy Servers metric. If the applications are unstable and connections to the backend server time out, the retry mechanism will route the requests to another backend server. As a result, access to the applications will be successful but there will be more access delay.
  5. If the problem persists, contact customer service.
