Azure Virtual Machines
The Azure Virtual machines are monitored based on the parameters or the attributes listed below. These attributes provide information about the functioning of Azure Virtual machines. You can also configure thresholds to the numerical attributes based on these details and get notified when the thresholds are violated.
Monitored Parameters
Go to the Monitors Category View by clicking the Monitors tab. Click on Azure Virtual Machines under the Cloud Apps Table. Displayed is the Azure Virtual Machine bulk configuration view distributed into 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.
