Azure Subscriptions Test

An Azure subscription is the basic unit where all resources are contained. It also defines several limits within Azure, such as number of cores, resources, etc.

In order to help administrators to keep track of the resources allocated to the target subscription and the resources that remain inactive and are not available for use, the eG Enterprise provides you with the Azure Subscriptions test.

This test helps administrators to figure out the state of the monitored subscription and the total number of resources allocated to that subscription, the number of geographic locations allocated to each subscription, etc. Using this test, administrators can figure out the number of inactive resources on a target subscription. This way, resources that are seldom used can be identified.

Target of the Test: A Microsoft Azure Subscription

Agent deploying the test: A remote agent

Output of the test: One set of results for the Microsoft Azure Subscription being monitored

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed.

Host

The host for which the test is to be configured.

Subscription ID

Specify the GUID which uniquely identifies the Microsoft Azure Subscription to be monitored. To know the ID that maps to the target subscription, do the following:

  1. Login to the Microsoft Azure Portal.

  2. When the portal opens, click on the Subscriptions option (as indicated by Figure 1).

    Figure 1 : Clicking on the Subscriptions option

  3. Figure 2 that appears next will list all the subscriptions that have been configured for the target Azure AD tenant. Locate the subscription that is being monitored in the list, and check the value displayed for that subscription in the Subscription ID column.

    Figure 2 : Determining the Subscription ID

  4. Copy the Subscription ID in Figure 2 to the text box corresponding to the SUBSCRIPTION ID parameter in the test configuration page.

Tenant ID

Specify the Directory ID of the Azure AD tenant to which the target subscription belongs. To know how to determine the Directory ID, refer to Configuring the eG Agent to Monitor a Microsoft Azure Subscription Using Azure ARM REST API.

Client ID, Client Password, and Confirm Password

To connect to the target subscription, the eG agent requires an Access token in the form of an Application ID and the client secret value. For this purpose, you should register a new application with the Azure AD tenant. To know how to create such an application and determine its Application ID and client secret, refer to Configuring the eG Agent to Monitor a Microsoft Azure Subscription Using Azure ARM REST API. Specify the Application ID of the created Application in the Client ID text box and the client secret value in the Client Password text box. Confirm the Client Password by retyping it in the Confirm Password text box.

Proxy Host and Proxy Port

In some environments, all communication with the Azure cloud be routed through a proxy server. In such environments, you should make sure that the eG agent connects to the cloud via the proxy server and collects metrics. To enable metrics collection via a proxy, specify the IP address of the proxy server and the port at which the server listens against the Proxy Host and Proxy Port parameters. By default, these parameters are set to none, indicating that the eG agent is not configured to communicate via a proxy, by default.

Proxy Username, Proxy Password and Confirm Password

If the proxy server requires authentication, then, specify a valid proxy user name and password in the Proxy Username and Proxy Password parameters, respectively. Then, confirm the password by retyping it in the Confirm Password text box.

VM Snapthot Age in Days

By default, this parameter is set to 365 days by default. This means that, by default, this test will consider any snapshot that was created over 1 year ago as an 'old snapshot'. The count of such snapshots will be reported as the value of the Old VM snapshots measure. You can change the value of this measure, if you want to increase or decrease the age at which a snapshot becomes 'old' or 'obsolete', so it can be removed to conserve space.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measures reported by the test:
Measurement Description Measurement Unit Interpretation

Status

Indicates the current state of the subscription.

 

The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
Enabled 1
Unknown 0

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the current state of this subscription. In the graph of this measure however, the same is represented using the numeric equivalents only - 0 or 1.

With the help of the detailed diagnosis of this measure, you can determine the display name and Quota ID of the monitored subscription.

Total GEO locations

Indicates the number of geographic locations allocated to the subscription.

Number

The detailed diagnosis of this measure lists the name of the geographic locations that are allocated to each subscription.

Total resources

Indicates the total number of resources that can be allocated to the subscription.

Number

 

Active resources

Indicates the number of resources that are currently active on the subscription.

Number

The detailed diagnosis of this measure lists the name of the resource provider and the name of the resources provided through each resource provider that are active for each subscription.

Inactive resources

Indicates the number of resources that are currently inactive on the subscription.

Number

The detailed diagnosis of this measure lists the name of the resource provider and the name of the resources provided through each resource provider that are inactive for each subscription.

Other resources

Indicates the number of resources that are currently in other states on the subscription.

Number

Use the detailed diagnosis of this measure to know which resources of the target subscription are in states other than Enabled or Unknown.

Active resource groups

Indicates the number of resource groups that are currently active on the subscription.

Number

Use the detailed diagnosis of this measure to know which resource groups of the target subscription are currently active.

Unused disks

Indicates the number of disks that are currently not used by the subscription.

Number

One of the major reasons your Azure storage costs may be higher than you expect is the presence of unused virtual hard disks (VHDs) in your Azure subscription. A key Azure cost management best practice is to find and delete all of these unused resources.\

Unused disks can accumulate after migration projects, diagnostic drives of VMs, or backups, but most unused disks are orphaned disks. When VMs are deleted, the disks are not deleted automatically, which leaves behind what are known as orphaned disks. These orphaned disks take up space and incur charges that most Azure users don’t even know they’re paying.

To identify unused disks, use the detailed diagnosis of this measure.

Unused network interfaces

Indicates the number of unused network interfaces.

Number

A network interface enables an Azure Virtual Machine to communicate with internet, Azure, and on-premises resources.

It is important to identify and delete unused network interfaces, as it helps save cloud costs. Usually, it is the orphaned NICs that stay unused for a long time. When you delete a VM in Azure, the NIC attached to the VMs will only be disassociated but it will not be deleted automatically and they will be left as Orphaned NICs. To identify such NICs, use the detailed diagnosis of this measure.

Unused unavailability sets

Indicates the number of availability sets that are unused.

Number

An availability set is a logical grouping of VMs that allows Azure to understand how your application is built to provide for redundancy and availability.

Like other Azure resources, unused availability sets also add to your cloud usage costs. To save costs, its best to identify unused availability sets and delete them. The detailed diagnosis of this test sheds light on the unused availability sets, and for how long they have not been used. If any availability set has been unused for a considerably long time, you may want to consider deleting that set.

Unused public Ips

Indicates the number of public IPs that the subscription is not using currently.

Number

Use the detailed diagnosis of this test to identify Public IPs that the subscription is not using, understand how long they have remained unused, and decide whether/not such IPs can be removed. Unused resources like public IPs often add to costs, and hece should be deleted.

Unused network security groups

Indicates the number of network security groups that the subscription is not using currently.

Number

You can use an Azure network security group to filter network traffic to and from Azure resources in an Azure virtual network. A network security group contains security rules that allow or deny inbound network traffic to, or outbound network traffic from, several types of Azure resources. For each rule, you can specify source and destination, port, and protocol.

Typically, empty groups with no rules and groups that are not associated with any subnets or network interfaces will not be used to filter network traffic. It is best if such unused groups are identified and deleted, as they will be unnecessarily adding to your cloud costs. To quickly identify the unused network security groups and understand how long they have been unused, use the detailed diagnosis of this measure.

Unused resource groups

Indicates the number of resource groups not used by the subscription presently.

Number

A resource group is a container that holds related resources for an Azure solution. The resource group can include all the resources for the solution, or only those resources that you want to manage as a group.

Unused resource groups impact Azure costs. To reduce this cost impact, it is recommended that you identify the unused groups and remove them. Use the detailed diagnosis of this measure for this purpose. With the help of detailed metrics, you can isolate the unused groups and the duration for which they have been idle. Based on this information, you can decide whether/not the resource group needs to be removed.

Unused route tables

Indicates the number of unused route tables.

Number

Azure automatically routes traffic between Azure subnets, virtual networks, and on-premises networks. If you want to change any of Azure's default routing, you do so by creating a route table.

One of the common reasons for a route table being unused is that it may not be associated with any subnet. Regardless of the reason for the poor usage, it is good practice to identify unused route tables and remove them, as such route tables needlessly escalate Azure costs. The detailed diagnosis of this measure leads you to unused route tables and how long they have not been used. This will help you figure out whether/not these route tables should be removed.

Unused load balancers

Indicates the number of load balancers that this subscription is not using currently.

Number

The detailed diagnosis of this measure leads you to the unused load balancers, reveals for how long they were idle, and thus, helps you determine whether/not they should be deleted to save Azure costs.

Unused app service plans

Indicates the current number of App Service Plans that are unused.

Number

An Azure App Service plan provides the resources that an App Service app needs to run.

App Service plans that have no apps associated with them still incur charges because they continue to reserve the configured VM instances. Likewise, an App Service Plan will continue to be billed, even if the app associated with that plan is not run, or does not use the resources in the plan. To minimize Azure costs therefore, use the detailed diagnosis of this measure to identify such unused plans, learn how long they ahve been unused, and then decide whether/not you want to delete them.

Virtual networks without subnets

Indicates the number of virtual networks that do not have subnets.

Number

Subnets enable you to segment the virtual network into one or more sub-networks and allocate a portion of the virtual network's address space to each subnet. You can then deploy Azure resources in a specific subnet. Just like in a traditional network, subnets allow you to segment your VNet address space into segments that are appropriate for the organization's internal network. This also improves address allocation efficiency.

Use the detailed diagnosis of this measure to identify those virtual networks that are not segmented using subnets, and determine how well such virtual networks have been utilized for communication. If the detailed metrics reveal virtual networks that have been idle for too long, you can atrribute the poor usage to the absence of subnets.

Traffic manager profiles without endpoints

Indicates the number of traffic manager profiles that are not configured with endpoints.

Number

Microsoft Azure Traffic Manager allows you to control how network traffic is distributed to application deployments running in different datacenters. You configure each application deployment as an 'endpoint' in Traffic Manager. When Traffic Manager receives a DNS request, it chooses an available endpoint to return in the DNS response. Traffic manager bases the choice on the current endpoint status and the traffic-routing method configured in the Traffic Manager Profile.

For the Azure Traffic Manager to work efficiently, you need to add one/more endpoints to a Traffic Manager Profile. Profiles without endpoints serve no purpose other than adding to your Azure costs. To minimize costs therefore, you need to identify those profiles that are not tied to any endpoints. The detailed diagnosis of this measure points you to such profiles and also reveals the duration for which such profiles were unused. Based on these detailed metrics, you can choose either to add endpoints to a profile and promote its usage, or to simply delete the profile and optimize costs.

Disabled traffic manager profiles

Indicates the number of traffic manager profiles that are currently disabled.

Number

Use the detailed diagnosis of this measure to identify those profiles that are disabled.

Old VM snapshots

Indicates the number of VM snapshots that are of or above the age configured against the VM Snapshot Age in Days parameter.

Number

Use the detailed diagnosis to know which are the old snapshots and how much storage space they occupy. You may want to consider deleting those old snapshots that are hogging storage space.

With the help of the detailed diagnosis of the Status measure, you can determine the display name and Quota ID of the monitored subscription.
