Host Template: Cloud - Azure - DNS Zones
Overview Copied
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 (Metric: 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: |
% |
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.
