Reference: Monitoring Azure virtual machine data

For more information about collecting and analyzing monitoring data for Azure virtual machines (VMs), see Monitoring Azure virtual machines.

Metrics

This section lists the platform metrics that are collected for Azure virtual machines and virtual machine scale sets.

Metric type	Resource provider / type namespace and link to individual metrics
Virtual machines	Microsoft.Compute/virtualMachines
Virtual machine scale sets	Microsoft.Compute/virtualMachineScaleSets
Virtual machine scale sets and virtual machines	Microsoft.Compute/virtualMachineScaleSets/virtualMachines

For more information, see a list of platform metrics that are supported in Azure Monitor.

Metric dimensions

For more information about metric dimensions, see Multi-dimensional metrics.

Azure virtual machines and virtual machine scale sets have the following dimensions that are associated with their metrics.

Dimension name	Description
LUN	Logical unit number
VMName	Used with virtual machine scale sets

Azure Monitor Logs tables

This section refers to all the Azure Monitor Logs tables that are relevant to virtual machines and virtual machine scale sets and available for query by Log Analytics.

Resource type	Notes

For reference documentation about Azure Monitor Logs and Log Analytics tables, see the Azure Monitor Logs table reference.

Activity log

The following table lists a few example operations that relate to creating virtual machines in the activity log. For a complete list of possible log entries, see Microsoft.Compute Resource Provider options.

Operation	Description
Microsoft.Compute/virtualMachines/start/action	Starts the virtual machine
Microsoft.Compute/virtualMachines/restart/action	Deletes a managed cluster
Microsoft.Compute/virtualMachines/write	Creates a new virtual machine or updates an existing one
Microsoft.Compute/virtualMachines/deallocate/action	Powers off the virtual machine and releases the compute resources
Microsoft.Compute/virtualMachines/extensions/write	Creates a new virtual machine extension or updates an existing one
Microsoft.Compute/virtualMachineScaleSets/write	Starts the instances of the virtual machine scale set
