Control HostMonitoring

A device that can store, process, transmit or receive data.

Faulty instances of the virtual device Host can be detected by monitoring, halted, and a replacement provisioned automatically.

The device Host is monitored for reliability or availability, and if problems are found, its manager HostManager can take corrective action while waiting for updated software or hardware. This strategy represents a contingency plan included in the system operating policies and practices, e.g. to roll back software to an older but more reliable version or switch to a stand-in device from a different hardware vendor.

The device Host was found to have reliability or availability issues, and action has been taken by its manager HostManager to correct the problem. This strategy represents activation of a contingency plan at runtime, and can be selected to discover what effect this would have on risk levels, allowing this to be used for decision support calculations. To implement the plan at runtime, signal HostManager that the problem was detected with Host.
