How Can I Check High Access Delay of a Load Balancer?

  1. Bind an EIP to a backend server to make the applications accessible from the Internet and then check the access delay. By doing so, 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 maximum bandwidth set for the EIP, the access delay increases.
  3. Check application workloads and security policies if there is high delay when the applications are accessed from the Internet.
  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 is successful but the access delay increases.
  5. If the problem persists, contact customer service.
