Why Cannot I Install or Upgrade Agents in Batch?

Conditions for batch Agent installation or upgrade:

• The host is running, and the Agent status is Running.
• The host is running, the Agent status is Not installed, and the host OS supports one-click installation. For details about supported OSs, see What OSs Does the Agent Support?

Possible causes for Agent installation or upgrade failures:

• The host is not in the running state.
• The Agent status is faulty. For details about troubleshooting methods, see What Should I Do If the Agent Status Is Faulty?
• The Agent is not installed, but the host OS does not support one-click installation. You need to log in to the cloud server and run the installation command to install or upgrade the Agent. For details, see Installing the Agent.
