Azure Virtual Machines

A Microsoft Azure Virtual Machine (VM) provides scalable computing capacity in the Microsoft Azure cloud.

When an Azure VM entity is selected, Cisco Cloud Observability implicitly monitors Azure VM Scale Sets (VMSS) that are used for K8s worker nodes. See What are virtual machine scale sets? in the Microsoft Azure documentation for more information.

You must configure cloud connections to monitor this entity. See Configure Azure Cloud Connection.

Cisco Cloud Observability displays Azure entities on the Observe page. Metrics are displayed for specific entity instances in the list and detail views.

Detail View

To display the detail view for an Azure Virtual Machine instance:

Navigate to the Observe page.
Under Compute, click a Hosts group.
The Hosts list view now displays.
Click the Azure tab to display only Azure hosts.
Click a host Name to display the detail view.
The detail view displays metrics, key performance indicators, and properties (attributes) related to the instance you selected.
(Optional) If you have set up Host Monitoring, you can use the Data Source dropdown to choose a data source for your metrics. Selecting All Sources from the dropdown displays metrics from Microsoft Azure VMs (including Azure VM Scale Set Instances) and Cisco AppDynamics (Infrastructure Collector). Select the host from the dropdown to display metrics from a single source.

Metrics and Key Performance Indicators

Cisco Cloud Observability displays the following metrics and key performance indicators (KPIs) for Azure Virtual Machines. See Supported metrics with Azure Monitor.

Display Name	Source Metric	Description
CPU Utilization (%)	`Percentage CPU`	The percentage of time the CPU was busy processing system or user requests.
Disk Throughput (KiB/Sec)	`Disk Read Bytes` `Disk Write Bytes`	The amount of data per second read from all disk devices. The amount of data per second written to all disk devices.
Disk IOPs (Ops/Sec)	`Disk Read Operations/Sec` `Disk Write Operations/Sec`	The number of read operations per second performed on all disk devices. The number of write operations per second performed on all disk devices.
Network Throughput (KiB/Sec)	`Network In Total` `Network Out Total`	The amount of data per second received by all monitored network interfaces. The volume of data sent per second by all monitored network interfaces.
CPU Credits (vCPU-minutes)	`CPU Credits Remaining` `CPU Credits Consumed`	The number of credits available for the instance to spend to burst beyond its baseline CPU utilization. Only available on burstable cloud instances. The number of CPU credits spent (or consumed) by the instance for CPU utilization. Only available on burstable cloud instances.

Properties (Attributes)

Cisco Cloud Observability displays the following properties for Azure Virtual Machines.

Display Name	Property Name	Description
Location	`cloud.region`	The geographical region where the resource is running.
Host Name	`Name`	The name of the virtual machine instance.
Host ID	`Id`	The Azure-assigned ID of the virtual machine.
VM Size	`VmSize`	The size of the virtual machine.
OS Name	`OsName`	The name of the operating system used by the virtual machine.
OS Version	`OsVersion`	The version of the platform image or marketplace image used to create the virtual machine.
Proximity Placement Group	`Proximity`	Specifies information about the proximity placement group that the virtual machine should be assigned to.
Resource Group	`ResourceGroup`	The resource group that the virtual machine instance belongs to.
Subscription ID	`SubscriptionId`	The subscription ID of the operating system used by the virtual machine.
Private IP Address	`PrivateIpAddress`	The private IPv4 addresses of the virtual machine instance. This property depends upon the Infra Agent.
VM Scale Set Instance	`VmScaleSet`	A value of `true` indicates that the VM is part of a virtual machine scale set. If the VM is part of a general Azure VM, the value is `false` or blank.

Retention and Purge Time-To-Live (TTL)

For all cloud and infrastructure entities, the retention TTL is 180 minutes (3 hours) and the purge TTL is 525,600 minutes (365 days).
