Abstract: A method and system is disclosed for monitoring the status of a system by providing a health score. A health scoring module accesses a configuration management database (CMDB) comprising a plurality of configuration items referencing physical, service and process information. A target value for each configuration item is decided, followed by collecting their current value. Comparison operations are then performed between each configuration item's current and target value and a health subscore is generated. The resulting health subscore is then indexed to its corresponding configuration item. Once indexed, a health score is generated from a predetermined plurality of health subscores.

Abstract: An approach to providing failure protection in a loosely-coupled cluster environment. A node in the cluster generates checkpoints of application data in a consistent state for an application that is running on a first node in the cluster. The node sends the checkpoint to one or more of the other nodes in the cluster. The node may also generate log entries of changes in the application data that occur between checkpoints of the application data. The node may send the log entries to other nodes in the cluster. The node may similarly receive external checkpoints and external log entries from other nodes in the cluster. In response to a node failure, the node may start an application on the failed node and recover the application using the external checkpoints and external log entries for the application.

Abstract: An asset health monitoring system (AHMS) can assign a confidence indicator to some or all the services of a computing service provider. In response to drops in the confidence indicators, the AHMS can automatically initiate testing of services and/or computing assets associated with the services in order to raise confidence that a particular service and its computing assets will perform correctly. Further, the AHMS can automatically initiate remediation procedures for the particular service and/or specific computing assets that fail the confidence testing. By automatically triggering testing and/or remediation procedures, the AHMS can increase reliability of the computing service provider by preemptively identifying problems.
