How Do I Diagnose Network Routing Problems from a VM?
While supporting the VM environment as an admin, you may encounter the network routing issue, and you must know how to diagnose the routing problem. Once you create a virtual network, Azure creates several default outbound routes for network traffic.
The outbound traffic from all resources, like VMs, deployed in a virtual network, are routed based on Azure’s default routes. You might override Azure’s default routes or create additional routes. You may find that a VM can no longer communicate with other resources because of a specific route.
To troubleshoot the issue, you may check the next hop capability enables you to specify a source and destination IPv4 address. The next hop then tests the communication and informs you what type of next hop is used to route the traffic. You can then remove, change, or add a route to resolve a routing problem.

How Do I Monitor Azure Virtual Desktop Using Azure Monitor?
Azure Monitor is another tool that helps you in monitoring Azure Virtual Desktop. It is important to learn how to set up Azure Monitor for Azure Virtual Desktop to monitor your Azure Virtual Desktop environments. Prior to using Azure Monitor for Azure Virtual Desktop, you’ll need to set up the multiple things.
•\ You must have at least one configured Log Analytics workspace.
Make use of a designated Log Analytics workspace for your Azure Virtual Desktop session hosts to ensure that performance counters and events are collected only from session hosts in your Azure Virtual Desktop deployment.
•\ Allow data collection for the following things in your Log Analytics workspace:
\ a.\ Diagnostics from your Azure Virtual Desktop environment
\ b.\ Recommended performance counters from your Azure
Virtual Desktop session hosts
\ c.\ Recommended Windows Event Logs from your Azure Virtual
Desktop session hosts
•\ The data setup process explained in this page is the only one you’ll
need to monitor Azure Virtual Desktop. You can disable all other
items sending data to your Log Analytics workspace to save costs.
•\ Anyone monitoring Azure Monitor for Azure Virtual Desktop for your
environment will also need the read-access permissions that are
mentioned here:
\ a.\ Read-access to the Azure subscriptions that hold your Azure
Virtual Desktop resources
\ b.\ Read-access to the subscription’s resource groups that hold
your Azure Virtual Desktop session hosts
\ c.\ Read-access to the Log Analytics workspace or workspaces
Note Read-access permissions only let admins view data. However, they will need different permissions to manage resources in the Azure Virtual Desktop portal.
