Microsoft Azure Virtual Network Gateway

Microsoft Azure Virtual Network Gateway - An Overview

Virtual Network Gateway service provided by Microsoft Azure, allows to send encrypted traffic over the public internet between an Azure virtual network and an on-premises location. Applications Manager's Azure Virtual Network Gateway monitoring tool, facilitates the effective tracking of many key performance metrics of the virtual network gateways. It supports both ExpressRoute Gateway and VPN Gateway types.

Monitored Parameters

Navigate to the Category View by clicking the Monitors tab. Hover over 'Child Monitors' under Microsoft Azure in the Cloud Apps table, and then select the Virtual Network Gateways monitor from the displayed tooltip. This action will display the bulk configuration view for Azure Virtual Network Gateway in three tabs:

Availability tab gives the Availability history for the past 24 hours or 30 days.
Performance tab gives the Health Status and events for the past 24 hours or 30 days.
List view enables you to perform bulk admin configurations.

The Microsoft Azure monitor provides a brief detail of the Azure Virtual Network Gateway under the given subscription. Following are the list of metrics monitored in Azure Virtual Network Gateway Monitoring in their corresponding tabs:
