Amazon Route 53

Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service. Route 53 connects user requests to internet applications running on AWS or on-premises.

Cisco Cloud Observability supports monitoring the following Amazon Route 53 entities:

Health Check: Monitors the health and performance of your web applications, web servers, and other resources.
Resolver DNS Firewall Rule Group: Defines a named, reusable collection of DNS Firewall rules for filtering DNS queries.

You must configure cloud connections to monitor this entity. See Set up Cisco AppDynamics Cloud Collectors to Monitor AWS.

Cisco Cloud Observability displays AWS 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 Amazon Route 53 instance:

Navigate to the Observe page.
Under Networking & App Delivery, click AWS Route 53 Health Checks or AWS Route 53 DNS Resolver FRGs.
The list view now displays.
From the list, click an instance Name to display the detail view.
The detail view displays the metrics, key performance indicators, and properties (attributes) related to the instance you selected.

Metrics and Key Performance Indicators

Cisco Cloud Observability displays the following metrics and key performance indicators (KPIs) for Amazon Route 53. For more information, see:

Display Name	Source Metric Name	Description
Health Check Percentage (%)	`HealthCheckPercentageHealthy`	The percentage of Route 53 health checkers that consider the selected endpoint to be healthy.
SSL Handshake Time (ms)	`SSLHandshakeTime`	The average time, in milliseconds, that it took Route 53 health checkers to complete the SSL handshake.
Time To First Byte (ms)	`TimeToFirstByte`	The average time, in milliseconds, that it took Route 53 health checkers to receive the first byte of the response to an HTTP or HTTPS request.
Child Health Check - Healthy Count	`ChildHealthCheckHealthyCount`	For a calculated health check, the number of health checks that are healthy.
Health Check Status (Binary)	`HealthCheckStatus`	The status of the health check endpoint that CloudWatch is checking. 1 indicates healthy, and 0 indicates unhealthy.
Connection Time (ms)	`ConnectionTime`	The average time, in milliseconds, that it took Route 53 health checkers to establish a TCP connection with the endpoint.

Display Name	Source Metric Name	Description
Firewall Rule Group Query Volume (Query)	`FirewallRuleGroupQueryVolume`	The number of DNS Firewall queries that match a firewall rule group (specified by `FirewallRuleGroupId`).
Firewall Rule Group Query Volume by VPC ID (Query)	`FirewallRuleGroupVpcQueryVolume`	The number of DNS Firewall queries from a VPC (specified by `VpcId`).
Firewall Rule Group Query Volume by FDL ID (Query)	`FirewallRuleQueryVolume`	The number of DNS firewall queries that match a firewall domain list (specified by FirewallDomainListId) within a firewall rule group (specified by FirewallRuleGroupId).

Properties (Attributes)

Cisco Cloud Observability displays the following properties for Amazon Route 53.

Display Name	Property Name	Description
Type	`aws.route53.health_check.config.type`	The type of health check that you want to create, which indicates how Amazon Route 53 determines whether an endpoint is healthy.
Port	cloud.health_check.config.port	The port on the endpoint to perform health checks on.
FQDN	cloud.health_check.config.fqdn	The fully qualified DNS name of the endpoint to perform health checks.
Configured Regions	cloud.health_check.config.regions	List of regions which the health check is configured to monitor the endpoint.
Resource Path	cloud.health_check.config.resource_path	The path to performing health checks.
Request Interval	`aws.route53.health_check.config.request_interval`	The number of seconds between the time that Amazon Route 53 gets a response from your endpoint and the time that it sends the next health check request.
Health Threshold	`aws.route53.health_check.config.health_threshold`	The number of child health checks that are associated with a `CALCULATED` health check that Amazon Route 53 must consider healthy for the `CALCULATED` health check to be considered healthy.
Caller Reference	`aws.route53.health_check.caller_reference`	A unique string that you specified when the health check was created.
Service Principal	`aws.route53.health_check.service_principal`	Specifies if the health check or hosted zone was created by another service or the service that created the resource.

Measure Latency	`aws.route53.health_check.config.measure_latency`	Specifies if you want Amazon Route 53 to measure the latency between health checkers in multiple Amazon Web Services regions and your endpoint.
Failure Threshold	`aws.route53.health_check.config.failure_threshold`	The number of consecutive health checks that an endpoint must pass or fail for Amazon Route 53 to change the current status of the endpoint from unhealthy to healthy or vice versa.
Inverted	`aws.route53.health_check.config.inverted`	Specifies whether you want Amazon Route 53 to invert the status of a health check.
Disabled	`aws.route53.health_check.config.disabled`	Specifies if the health check is disabled.
