Microsoft Azure Virtual Machine Scale Sets

Microsoft Azure Virtual Machine Scale Sets - An Overview

Microsoft Azure Virtual Machine Scale Sets (VMSS) is a service in Microsoft Azure that allows users to deploy and manage a group of identical virtual machines (VMs) as a scalable set. VMSS is designed to help you build and manage large-scale, high-availability applications with ease. Monitoring Microsoft Azure Virtual Machine Scale Sets is crucial to ensure the performance, availability, and reliability of your applications that use the same. Use Applications Manager's Azure Virtual Machine Scale Sets Monitoring tool to monitor your Virtual Machine Scale Sets instances and their underlying infrastructure with ease.

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 VM Scale Sets monitor from the displayed tooltip. This action will display the bulk configuration view for Azure VM Scale Sets 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.

Microsoft Azure monitor provides a brief detail of the Azure Virtual Machine Scale Sets under the given subscription. Following are the list of metrics monitored in Azure VM Scale Sets Monitoring in their corresponding tabs:
