Why would Microsoft Azure provide both host and guest metrics?
My understanding is the Host metrics are stats of the machine that hosts the Azure VMs. This could mean a spike in host-level disk reads per second could mean that other guest VMs are causing it. Is this correct?
Why would Microsoft Azure provide both host and guest metrics?
Host-level metrics and Guest-level metrics all come from the same VM.
1.Azure host-level metrics from VM and VMSS without any additional diagnostic setup, to get Guest-level metrics, we should enable Azure diagnostics settings.
2.Azure support host-level metric by default, but Guest-level metrics get from Azure VM agent and store this data in an Azure storage account.
3.We can use host-level metrics to scale up or scale down, but guest-level metrics will not work for that.
