What Do I Do If an Installed Agent Is Not Displayed on the Console?

The agent status will be automatically refreshed 5 to 10 minutes after the installation succeeded.

If the agent is not displayed for a long time, possible causes are as follows:

The agent installation package does not match the ECS OS and version.
The remaining memory on the cloud server is insufficient during the installation.
The 100.125.X.X: port 443 is restricted.

If the problem is caused by a wrong installation package,
1. You need uninstall the install Agent package.
2. Obtain the package that matches the OS and version of the target ECS and reinstall the package.
If the problem is caused by insufficient memory,
1. Use a remote management tool, such as Xftp, SecureFX, or WinSCP, to log in to the server.
2. Run the following command to check the memory usage of the server:
  free -m
3. Check the value of free in the command output, as shown in Figure 1.
  Figure 1 Querying the memory
  
  If the value is less than 500 MB, the memory is insufficient. In this case, stop some applications or expand the capacity before installing the agent.
If the problem occurred because port 443 is restricted,
Ensure the online server where the agent is to be installed can communicate with the network segment. The security group of your server must allow outbound access to ports 443 on the 100.125.X.X/16 network segment.
