Azure Virtual Machines is one of several types of on-demand, scalable computing resources that Azure offers. An Azure virtual machine gives you the flexibility of virtualization without having to buy and maintain the physical hardware that runs the virtual machine. Azure Virtual Machines lets you create and use virtual machines in the cloud.

Azure Virtual Machines lets you create and use virtual machines in the cloud. Providing what's known as Infrastructure as a Service (IaaS), virtual machine technology can be used in variety of ways. Some examples are:

Virtual machines (VMs) for development and test : Development groups commonly use VMs because they offer a quick, easy way to create a computer with specific configurations required to code and test an application. Azure Virtual Machines provides a straightforward and economical way to create these VMs, use them, then delete them when they're no longer needed.

Running applications in the cloud : It makes economic sense to run some applications in the public cloud. One example is an application that has large spikes in demand. Although you could equip your own data center with enough hardware to handle peak demand, that hardware might be underutilized much of the time. Running this application on Azure lets you pay for extra VMs only when you need them and shut them down when you don't. Or, suppose you're a start-up that needs on-demand computing resources quickly and with no commitment. Once again, Azure can be the right choice.

Extending your own datacenter into the public cloud : When you use Azure Virtual Network, your organization can create a virtual network (VNET) that's an extension of your own on-premises network and add VMs to that VNET. This allows running applications such as SharePoint, SQL Server and others on an Azure VM. This approach might be easier to deploy or less expensive than running them in VMs your own datacenter.

Disaster recovery : Rather than paying continuously for a backup datacenter that's rarely used, IaaS-based disaster recovery lets you pay for the computing resources you need only when you really need them. For example, if your primary datacenter goes down, you can create VMs running on Azure to run essential applications, then shut them down when they're no longer needed.

When multiple virtual machines are hosted on the Azure cloud, administrators may often want to figure out if each virtual machine in the cloud is used optimally. In order to closely monitor the virtual machine and figure out the resource utilization of each virtual machine, administrators can use the AzureVmPerfTest test.

This test monitors the current state and the amount of resources that each virtual machine on the Azure cloud is taking up. Using the metrics reported by this test, administrators can determine which virtual machine in the cloud is taking up most CPU, which virtual machine is generating the most network traffic, which virtual machine has the maximum IOPS, etc.

Note:

eG Enterprise cannot auto-discover and monitor the Virtual Machines deployed through the Azure Resource Manager whereas Virtual Machines deployed in Azure Classic mode can be monitored.

Output of the test : One set of results for each virtual machine of the target Microsoft Azure being monitored

First level Descriptor : Virtual Machine

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
VmStatus Indicates the current status of this virtual machine.   The values reported by this measure and its numeric equivalents are mentioned in the table below:

Numeric Value Measure Value
1 RoleStateUnknown
2 CreatingVM
3 StartingVM
4 CreatingRole
5 StartingRole
6 Running
7 BusyRole
8 StoppingRole
9 StoppedRole
10 StoppingVM
11 StoppedVM
12 RestartingRole
13 CyclingRole
14 FailedStartingRole
15 FailedStartingVM
16 UnresponsiveRole
17 StoppedDeallocated
0 Offline

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the current status of this virtual machine. The graph of this measure however, represents the status of a server using the numeric equivalents only - 0 to 17.

DiskRead Indicates the rate at which data is read from the disks of this virtual machine. MB/Sec A high value of this measure indicates that the disks are experiencing high I/O activity.
DiskWrite Indicates the rate at which data is written from the disks of this virtual machine. MB/Sec  
NetOut Indicates the amount of data bytes received by all the network interfaces connected to this virtual machine. MB Comparing the value of this measure across the virtual machines will help you to identify the virtual machine that is hogged with incoming network data.
NetIn Indicates the amount of data bytes sent through all the network interfaces connected to this virtual machine. MB Comparing the value of this measure across the virtual machines will help you to identify the virtual machine through which maximum amount of data traffic passes through.
CpuPercent Indicates the average percentage of CPU utilized by this virtual machine. Percent A very high value of this measure indicates that the VM is currently utilizing high memory resources.
CpuCores Indicates the total number of CPU cores allocated to this virtual machine. Number  
Memory Indicates the amount of memory that is configured for this virtual machine. GB  
MaxDiskSizes Indicates the maximum amount of disk space allocated for this virtual machine. GB  
TempDiskSizes Indicates the amount of temporary disk space that is allocated for this virtual machine. GB  
MaxDataDisks Indicates the maximum number of data disks allocated to this virtual machine. Number  
MaxIOPS Indicates the maximum amount of data space allocated for IOPS on this virtual machine. GB
