What should you use?

B. Azure HDInsight
C. Linux Diagnostic Extension (LAD) 3.0
D. Azure Analysis Services
Explanation:
You can use extensions to configure diagnostics on your VMs to collect additional metric data.
The basic host metrics are available, but to see more granular and VM-specific metrics, you need to install the Azure diagnostics extension on the VM. The Azure diagnostics extension allows additional monitoring and diagnostics data to be retrieved from the VM.
