Monitoring and troubleshooting network connectivity in a cloud environment like Microsoft Azure is a crucial skill set for IT professionals. Especially for those preparing for the AZ-140 Configuring and Operating Microsoft Azure Virtual Desktop exam, understanding these operations is a fundamental requirement. This article will walk you through the practices needed to keep your Azure Virtual Desktop (AVD) environment running smoothly.
Section 1: Monitoring Network Connectivity
Monitoring network connectivity is a crucial first step in maintaining the health of your AVD environment. Azure provides a set of in-built services and resources to help monitor and diagnose health and performance issues.
Azure Network Watcher
Azure Network Watcher is a regional service that enables you to monitor and diagnose health and performance issues in your network scenario. It provides several tools like IP flow verify, Next hop, Connection troubleshoot, Network performance monitor, and Traffic analytics.
Connectivity Check
Azure allows us to perform a connectivity check from a VM to a destination which could be another VM, FQDN, URI or IPv4 address. This helps in identifying any connectivity issues and helps us to isolate the problem.
Network Performance Monitoring (NPM)
NPM is a cloud-based hybrid network monitoring solution that helps you monitor network performance between various points in your network infrastructure. It also helps monitor network connectivity to service and application endpoints.
Section 2: Troubleshooting Network Connectivity
Troubleshooting network connectivity in Azure largely revolves around interpreting and reacting to network connectivity test results or system logs.
Connection Troubleshoot
Using the Connection troubleshoot tool in Network watcher, we can test the reachability of a VM and get latency and packet loss statistics. This utility tests the connection from source to destination at a specified port and helps in identifying the connectivity issues.
For example, if a VM cannot connect to a SQL Server, the tool can be used to check connectivity, and it will provide you with detailed insights into the issue and possible ways to resolve it.
Network Logs
Network logs can provide valuable insights into the operational health of your Azure environment. Azure provides two categories of network logs: NSG flow logs and Azure Monitor logs.
NSG flow logs enable you to capture information about traffic for Network Security Groups (NSG). You can use this information to diagnose any undesired network connectivity.
Azure Monitor logs are comprehensive logs that can be used to trace network activities. With Azure Monitor logs, you can query, consolidate, and analyze your data from various Azure services.
Packet Capture
Packet capturing is a powerful tool that allows you to track traffic to and from a VM. Network Watcher’s packet capture allows you to create capture sessions that track traffic and store captured data locally or on a storage account.
Section 3: Best Practices and Preemptive Measures
While monitoring and troubleshooting form an important part of network management, good design and proactive measures help mitigate major issues.
Following best practices in setting Network Security Group (NSG) rules and creating effective subnet architecture can prevent many connectivity issues. Regularly monitoring the Performance Monitor for any abnormal spikes and taking necessary action can greatly reduce the chances of severe performance degradations.
In conclusion, monitoring and troubleshooting network connectivity in Azure Virtual Desktop is an integral part of ensuring the health and performance of your AVD environment. Both reactive and preventive measures must be used effectively along with the use of the various tools available in Azure. Understanding these tools and methodologies will also aid in your preparation for the AZ-140 Exam.
