Monitoring VPN Connectivity From Azure Virtual Machine To On-premises Server

Introduction

The Azure connection monitor is a perfect monitoring tool that generates synthetic traffic to test the connectivity and measure response time; in this article, we will learn how to monitor Network connectivity from Azure Virtual Machine to On-premises Servers.

Prerequisites

• Azure Virtual Machine
• Active VPN Connection
• On-premises Server IP Address

Step 1: Open the Azure Virtual machine, click Extension + applications under Settings, and click + Add to install the Microsoft Monitoring Agent.

Step 2: Select the Network Watcher Agent for Windows, Click Next, and then click Create.

Step 3: Open the Network watcher, click the Connection monitor under Monitoring, and then click + Create.

Step 4: Enter the name for the Connection Monitor and click Next: Test groups.

Step 5: In the Add test groups details page, enter the name for the test group, and click Add source.

Step 6: Select the source type as Virtual Machines, select the Virtual Network you need to monitor the connectivity from source to destination, select the Virtual Machine, and click Add endpoint.

Step 7: Enter the name for the Test configuration Name, select the ICMP-Packets under the Protocol, and then click Add Test Configuration.

Step 8: On the Add Destination part, select the External Addresses and click Add Endpoint.

Step 9: In the Endpoint (URL/IP), enter the IP address for your On-premises server IP address and click Save.

Step 10: We have successfully added the Sources, Test configurations, and Destinations, so click Add Test Group and Next: Create Alert to create the alert.

Step 11: Select Create action group, enter the email address, click Create action group, and click Done.

Step 12: Click Review + Create button to create the connection monitor.

Step 13: Now the connection monitor status is enabled, and there are no Fail or Warning alerts in the monitor.

Step 14: To test the alert, I’m going to delete the VPN Connection, so go to the Local Network Gateway, select the connection, right-click the connection, and click Delete.

Step 15: We got an alert email from Azure Monitor.

Step 16: When we open the connection monitor, it shows a Fail notification.
