Examples of com.cloud.exception.ConnectionException

com.cloud.exception.ConnectionException
ConnectionException is thrown by Listeners while processing the startup command. There are two uses for this exception and they are distinguished 1. If the flag is set to true, there is an unexpected error during the processing. Upon receiving this exception, the AgentManager will immediately place the agent under alert. When the function to enable to disable the agent, the agent is disabled. should be disconnected and reconnected to "refresh" all resource information. This is useful when the Listener needed to perform setup on the agent and decided it is best to flush connection and reconnect. situation where it keeps throwing ConnectionException.
