A distributed computing system includes a plurality of intercommunicating component machines. In a method for alert processing, when a component machine fails to perform an operation, and no alert information regarding that operation is currently stored by that component machine, peer machines among the component machines are identified with regard to the operation. Notification is sent to the peer machines regarding failure to perform the operation, notifying the peer machines to store alert information regarding the operation. The component machine stores the alert information regarding the operation and issues an alert corresponding to the failure to perform the operation. A computer readable medium containing executable instructions is also described.
