Generally, application operations fail because EDAS Agent runs improperly.
Log on to the EDAS console and choose Resource Management > ECS on the left-side menu bar.
On the instance list page, view the Agent Status.
If the EDAS Agent has been installed successfully on the instance, its status is Online or Docker Online.
If EDAS Agent installation fails, its status is Unknown or Exception.
If the status of EDAS Agent is “Exception”, see “Unknown” or “Exception” status after EDAS Agent is installed for troubleshooting.
