Azure api to get metrics data for multiple Virtual Machines

Question

Hi,

I am looking for the azure rest api to get performance metrics data for multiple resources (VMs) in a single request.

I went through the documentation and found that the Get request for only one VM per request-

https://management.azure.com/subscriptions/{SubscriptionID}/resourceGroups/{ResourceGroupName}/providers/Microsoft.Compute/virtualMachines/{VM Name}/providers/microsoft.insights/metrics?api-version=2019-07-01&metricnames=Percentage CPU

Please suggest.

Thanks

Hi,
You can use the same API but not provide the part about the VM. Keep in mind that the API works only for VMs and a few other resources at subscription level and you need to provide region. You can only get the metrics for all VMs in a subscription in one region. If you have VMs in another region you need to make separate call.

Example call with ARM client is:

armclient get "/subscriptions/<sub id>/providers/microsoft.Insights/metrics?timespan=2020-09-14T06:30:00.000Z/2020-09-15T06:45:00.000Z&interval=PT15M&metricnames=Percentage CPU&aggregation=average&metricNamespace=microsoft.compute%2Fvirtualmachines&top=10&orderby=average desc&autoadjusttimegrain=true&validatedimensions=false&api-version=2017-12-01-preview&region=westeurope"

(Please mark the reply as answer if it is the solution to your problem.

Hi Stan,

By using the suggested api we are not able to track VM wise metrics data for a subscription.

e.g. A subscription has multiple VMs and we need the metrics value for each VM for that subscription in a single request.

Please suggest.
