Azure DNS Zone Monitoring

Host Template: Azure DNS Zone Monitoring

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

Azure DNS is a hosting service for DNS domains. It provides name resolution using the Microsoft Azure infrastructure and allows efficient management of DNS records using the same credentials, APIs and tools as other Azure services. Since the Azure DNS service is based on the Azure Resource Manager, it provides the same Resource Manager features, such as; role based access control, activity logs and resource locking. As well as this, Azure DNS also supports private DNS domains, allowing you to use your own custom domain names.

This Host Template allows you to monitor all the metrics you need to efficiently run Azure DNS Zones on Microsoft Azure. After installation, you'll be able to check the number of queries served, the number of record sets as well as the percentage of record set capacity utilized by a DNS Zone.

This Host Template includes the following Service Checks:

Service Check Name	Description	Default Thresholds (Warning, Critical)	UOM
Azure - DNS Zone - Query Volume	Total number of Bytes transmitted within time period [Default Timespan = 240mins, Default Check Interval = 60mins]	N/A	N/A
Azure - DNS Zone - Record Set Capacity	Percent of Record Set capacity utilized by a DNS zone [Default Timespan = 240mins, Default Check Interval = 60mins]	record_set_capacity_utilization=70,90	%
Azure - DNS Zone - Record Set Count	Number of Record Sets in a DNS zone [Default Timespan = 240mins, Default Check Interval = 60mins]	N/A	N/A

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.

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:

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

--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 - DNS Zone - Query Volume	`Az.Net.DNS.Query.Volume`
Azure - DNS Zone - Record Set Count	`Az.Net.DNS.Record.Count`
Azure - DNS Zone - Record Set Capacity	`Az.Net.DNS.Record.Capacity`
