# How Do I Check the Status of a Backend Server?

1. Verify that the applications on the backend server are enabled.
   1. Log in to the backend server. (An ECS is used as an example here.)
   2. Check the port status.

      netstat -ntpl

      For Windows ECSs, use netstat -ano on the CLI to view the port status or server software status.

2. Check the network communication of the ECS.

   For example, if the ECS uses port 80, use curl to check whether network connectivity is normal.
