The overall Health of your virtual machine (VM) needs utmost care, and so it is vital to screen the health of your virtual machine regularly. But it is a challenge since you cannot review each metric and alert all the time to screen the health of a virtual machine.

But now you can use Azure Monitor for virtual machines guest health feature. The attribute monitors the health of your virtual machines and issues an alert if any parameter being monitored is not within the acceptable range.

The feature provides its users with competence to-

• Thoroughly monitor the overall health of virtual machines
• Monitor health based on crucial VM metrics to track the overall health and capacity of the virtual machine.
• Take on time actions after instant alerts notifying if the virtual machine is not in a good health

Virtual machine guest health feature works on a parent-child hierarchic model that checks out the health state of disks, CPU, and memory for a VM. It notifies the user about any significant change. The customer can set a threshold for each child to monitor and define Healthy, Warning, and Critical.

Each monitor screens the health of a specific component. The health of its monitors defines the health of the virtual machine.

The apex level monitor on the Virtual Machine groups the health state of all the child monitors. It provides a single health state of the VM. It matches the condition of the child monitor with the least healthy state.

View the Health of Each Virtual Machine!

Users can critically analyse the health of every VM in their subscription and resource group in the Guest VM health column from the ‘get started’ section of Azure Monitor for VMs.

Users can also enable the alert status from this tab if they want to get an alert upon the state change of the monitor.

The Cost

No direct cost for the guest health feature in Azure Monitor for virtual machines, but there is a cost for uptake and storage of health state data in the Log Analytics workspace.

All important data are stored in the HealthStateChangeEvent table.
