Azure VM Scale Sets Monitoring

Host Template: Cloud - Azure - Virtual Machines Scale Sets

This host template is one of 31 developed by Opsview to provide the most comprehensive Azure monitoring in the industry.

Azure Virtual Machine Scale Sets are groups of individual virtual machines (VMs) within the Microsoft Azure public cloud that Information Technology (IT) administrators can configure and manage as a single unit.

This Host Template includes the following Service Checks:

Service Check Name	Description	Default Thresholds (Warning, Critical)	UOM
Azure - VMSS - Bytes Read	The number of bytes read by the VMSS [Default Timespan = 5mins, Default Check Interval = 5mins]	N/A	B
Azure - VMSS - Bytes Written	The number of bytes written by the VMSS [Default Timespan = 5mins, Default Check Interval = 5mins]	N/A	B
Azure - VMSS - Bytes Read Operations	The number of bytes read operations by the VMSS per second [Default Timespan = 5mins, Default Check Interval = 5mins]	N/A	per_second
Azure - VMSS - Bytes Write Operations	The number of bytes write operations by the VMSS per second [Default Timespan = 5mins, Default Check Interval = 5mins]	N/A	per_second
Azure - VMSS - Network In	The number of bytes received by the VMSS [Default Timespan = 5mins, Default Check Interval = 5mins]	N/A	B
Azure - VMSS - Network Out	The number of bytes sent by the VMSS [Default Timespan = 5mins, Default Check Interval = 5mins]	N/A	B
Azure - VMSS - Percentage CPU	The percentage CPU usage [Default Timespan = 5mins, Default Check Interval = 5mins]	percentage_cpu=70,90	%

NOTE: The "Default Timespan" given for these Service Checks refers to the time period we use when retrieving metrics from Azure.

NOTE: See details about Nagios thresholds here.

Usage Instructions

To use this Host Template you will need to provide access to the subscription you wish to monitor

Navigate to the Subscriptions section and select your Subscription.

In the Subscription to be monitored, click Access Control (IAM).

Then click the Add button, select the required role and select the application, once for each of the following roles: * Reader

Repeat these steps for each subscription you wish to monitor.

Step 1: Add this Host Template

Add the Cloud - Azure - Virtual Machines Scale Sets Host Template to your Opsview Monitor host. If the resource you're monitoring has no hostname or public IP, then open the Advanced settings pane and change Host Check Command to Always assumed to be UP.

For more information, refer to Opsview Knowledge Center - Adding Host Templates to Hosts.

Step 2: Add and configure variables required for this Host Template

The Service Checks in this Host Template use the following variables, and they will be added to your Opsview Monitor instance when you import the Opspack:

AZURE_CREDENTIALS

The Value is not used and therefore can be set to anything. Override the arguments with your Azure Credentials.

Parameter	Position in Variable	Name	Description
--subscription-id	Arg1	Subscription ID	The Subscription ID of your Azure Subscription
--client-id	Arg2	Client ID	The Client ID of your Azure Subscription
--secret-key	Arg3	Secret Key	The Secret Key of your Azure Subscription
--tenant-id	Arg4	Tenant ID	The Tenant ID of your Azure Subscription

AZURE_RESOURCE_DETAILS

The Value is not used and therefore can be set to anything. Override the arguments with your Azure Resource Details.

--resource-group	Arg1	Resource Group	Name of the Azure resource group to be monitored
--resource-name	Arg2	Resource Name	Name of the Azure resource to be monitored

For more information, refer to Opsview Knowledge Center - Adding Variables to Hosts.

For mode-specific help, run the plugin with the -h -m <mode> flags. This will list the required and optional Variable Arguments for that mode. The appropriate mode for each Service Check is listed here:

Service Check Name	Mode
Azure - VMSS - Bytes Read	`VMSS.BytesRead`
Azure - VMSS - Bytes Written	`VMSS.BytesWritten`
Azure - VMSS - Bytes Read Operations	`VMSS.ReadOperations`
Azure - VMSS - Bytes Write Operations	`VMSS.WriteOperations`
Azure - VMSS - Network In	`VMSS.NetworkIn`
Azure - VMSS - Network Out	`VMSS.NetworkOut`
Azure - VMSS - Percentage CPU	`VMSS.PercentageCPU`
