摘要

A system for monitoring a virtual machine executed on a host. The system includes a processor that receives an indication that a failure caused a storage device to be inaccessible to the virtual machine, the inaccessible storage device impacting an ability of the virtual machine to provide service, and applies a remedy to restore access to the storage device based on a type of the failure.

1. A system for monitoring software application instances, the system comprising:
a host executing a software application instance; and a processor programmed to:
receive an indication that a failure caused a storage device to be inaccessible to the software application instance and impacted an ability of the software application instance to provide service;determine if the failure is permanent or transient; andapply a remedy comprising:
if the failure is permanent, terminating the software application instance and restarting the software application instant on a healthy host, andif the failure is transient, waiting for a predefined period of time, and if the transient failure does not clear within the predefined period of time, terminating the software application instance and restarting the software application instance on a healthy host.
