Azure Virtual Machines


Azure Virtual Machines - An Overview

The Azure Virtual Machines are monitored based on the parameters or the attributes listed below. These attributes provide information about the functioning of the Azure Virtual Machine. Using Applications Manager's Azure Virtual machines monitoring tool, you can also configure thresholds to the numerical attributes based on these details and get notified when the thresholds are violated.

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 Machine monitor from the displayed tooltip. This action will display the bulk configuration view for Azure Virtual Machine 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.

Click on the monitor name to see all the server details listed. Following are the list of metrics monitored in Azure Virtual machines monitoring in their corresponding tabs:

Note:
  • Data collection for the following metrics is done via the following methods:
    Metrics to be monitoredData collection methodRequired Privileges
    Azure monitor Via Azure APIs ---
    Diagnostic Extension Via Storage Table APIs Diagnostic Extension should be enabled for the virtual machines. (Windows and Linux)
    Guest OS Via PowerShell scripts PowerShell remoting should be enabled.
  • Guest OS metrics will be available only for Windows installations of Applications Manager for Windows VMs alone.
  • Reader role-based applications used for monitoring have constraints when it comes to fetching Diagnostic Extension metrics in Azure VM Monitor.
  • Applications Manager can collect diagnostic metrics from Storage accounts in both public and private links, as long as the storage account is accessible from the machine where Applications Manager is installed. For additional information, please refer to this link.
