How to get a list of VMs that have Azure Monitor enabled using the REST API

Question

On the Overview tab on https://portal.azure.com/#view/Microsoft_Azure_Monitoring/AzureMonitoringBrowseBlade/~/virtualMachines, there is a list of Virtual Machines that have Azure Monitor enabled.

I have been trying to get a list of those VMs through the Azure REST API but without success. Is there a way to get the VMs?

I have tried the following methods:

Called the API endpoint "https://management.azure.com/{resourceId}/providers/Microsoft.Insights/vmInsightsOnboardingStatuses/default?api-version=2018-11-27-preview". It does return some VMs that have Azure Monitor enabled but not all.

Used a KQL query on the Log Analytics API to get the heartbeats of VMs. It returns the heartbeats of all VMs including those that don't have Azure Monitor enabled. There seems to be no way of filtering out VMs without Azure Monitor.

Answer 1

Hello,

If you are looking to see which of the connected VMs are having the Virtual Machines Insights enabled in Azure Monitor, you can run the following Kusto Query on the Workspace where the VMs are connected:

Heartbeat
| where Solutions contains "VMInsights"
| distinct Computer, OSType

When an agent is sending its heartbeat to the Workspace, beside other information, it will also provide a list of the solutions that are enabled on that agent.
That's why when you see VMInsights present in that Solutions property of the Heartbeat, it means that the agent was also enabled with VM Insights from Azure Monitor.

Hope it helps!

Running this Kusto Query on your Workspace will tell you which agents are reporting that they have the Virtual Machines Insights (Azure Monitor) enabled:

Heartbeat
| where Solutions contains "VMInsights"
| distinct Computer, OSType
