I am trying to collect the Performance of a Virtual Machine like CPU Utilization, Available Memory, Logical Disk MB/s, and Logical Disk IOPS, which can be seen under Insights via console. I want to collect these data and save them into a CSV file. Is there any API to get the data with Avg, Min, Max, 50th, 90th, and 95th included?
I have tried the following solutions:
- az monitor metrics command: az monitor metrics list --resource {ResourceName} --metric "Percentage CPU"
- API: https://management.azure.com/subscriptions/{subscription_id}/resourceGroups/{resource_group_name}/providers/Microsoft.Compute/virtualMachines/{vm_name}/providers/microsoft.insights/metrics?api-version=2018-01-01&metricnames=Percentage CPU×pan={start_time}/{end_time}&interval=PT1H&aggregation=average
3. Microsoft Azure Monitor Client Library (Python SDK): azure-mgmt-monitor
In all the above-mentioned approaches, Instead of CPU Utilization, I'm getting results of 'Percentage CPU', i.e., instead of Insights these approaches are giving metrics.

I'm seeing the same thing you are and I suspect that there is a separate approach to gathering the VM Insights data. I'm going to update the tags so that this gets seen by the Azure Monitor experts.
