Utilizing device signals to improve the recovery of virtual machine host devices

A system including:

• at least one processor at a server device;
• and
• a computer memory including instructions that, when executed by the at least one processor at the server device, cause the system to carry out operations including:
• receiving, at a management entity, a power-draw signal corresponding to a power draw by a host system on a host device;
• determining, at the management entity, that the host device is unhealthy using a power failure detection model that determines power-draw failings of host devices based on power-draw signals or usage characteristics of the host devices;
• and
• initiating, from the management entity, a recovery process to recover the host device based on determining that the host device is unhealthy.

A computer-implemented method, including:

• receiving, at a management entity, a power-draw signal corresponding to a power draw by a host processor and host memory on a host device;
• generating a power failure detection model that includes a first rule-based layer and a second machine-learning layer having a power failure machine-learning model, wherein the power failure detection model determines power-draw failings of host devices based on power-draw signals and usage characteristics of the host devices;
• determining, at the management entity, that the host device is unhealthy by comparing the power-draw signal to a power-draw range determined by the power failure detection model for the host device based on one or more usage characteristics of the host device;
• and
• initiating, from the management entity, a recovery process to recover the host device based on determining that the host device is unhealthy.
