How Do I Enable Diagnostics On My Azure Instance?

Here is a quick guide on how to enable diagnostics for an ARM Instance (VM) in Azure: 

1. In Azure Control Panel on Azure Portal, go to Virtual Machines and select the VM in question (you should do this for ALL of your VMs and all other resources)
2. Scroll down to Diagnostics Settings. 
3. Click on Diagnostics Settings, and set the Status to On.

If you have a lot of VMs, you can use this process in order to use PowerShell to enable Diagnostics for VMs.
