Monitor AWS Route53

Overview

Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service. Route 53 is used to perform three main functions in any combination: domain registration, DNS routing, and health checking. The Route53 plugin enables you to monitor the performance of Route53 by gathering metrics and its functions using sfPoller and display the metrics within SnappyFlow dashboard.

Prerequisites

To collect metrics from Route53, it is necessary to have an IAM Role with CloudWatch access and sfPoller set up within your AWS environment. Click here to learn more about setting up sfPoller in your AWS environment.

Configure sfPoller to Collect Metrics

Follow the below step to add endpoints and plugins in sfPoller.

1. Go to the Application tab of sfPoller and navigate to your Project > Application.

2. Select the Application, it will take you to the Endpoint page.

   

3. In the Endpoint page, select the Add Endpoint button, add the following data, and save.

   • Service Type: Select AWS Service
   • Account Name: Select aws
   • Endpoint Type: Select Route53
   • Name: Give a name to the endpoint
   • Instance Name: Give the instance name

4. In the Plugins window, select the +Add button.

   

5. In the Add Plugin window, select the below details and save.

   • Plugin Type: Select Metric
   • Plugin: Select cloudwatch-route53
   • Interval: Choose an interval value. The minimum value for the interval is 300
   • Status: By default, the status is Enabled

6. Click the global Save button in the window's top right corner to save all the changes made so far.

View AWS Route53 Metrics

Follow the below steps to view the metrics collected from Route53.

1. Go to the Application tab in SnappyFlow and navigate to your Project > Application > Dashboard.

note

Once plugin is added to sfPoller, they will be automatically detected within the Metrics section. However, if the plugins are not detected, you can import template to view the corresponding metrics.

3. To access the unprocessed data gathered from the plugins, navigate to the Browse data section and choose the Index: Metric, Instance: Endpoint, Plugin, and Document Type.

Template Details

Template	Plugin	Document Type	Description
Route53	cloudwatch-route53	healthCheckMetrics, hostedZoneMetrics, resolverEndpointMetrics	Collects metrics from Route53

Metric List

Health Check Metrics

Metric	Description
ConnectionTime	The average time, in milliseconds, that it took Route 53 health checkers to establish a TCP connection with the endpoint.
HealthCheckPercentageHealthy	The percentage of Route 53 health checkers that consider the selected endpoint to be healthy.
HealthCheckStatus	The status of the health check endpoint that CloudWatch is checking. 1 indicates healthy, and 0 indicates unhealthy.
SSLHandshakeTime	The average time, in milliseconds, that it took Route 53 health checkers to complete the SSL handshake.
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.

Hosted Zone Metrics

Metric	Description
DNSQueries	For all the records in a hosted zone, the number of DNS queries that Route 53 responds to in a specified time period.
DNSSECInternalFailure	Value is 1, if any object in the hosted zone is in an INTERNAL_FAILURE state. Otherwise, value is 0.

Resolver Endpoint Metrics

Metric	Description
EndpointHealthyENICount	The number of elastic network interfaces in the OPERATIONAL status. This means that the Amazon VPC network interfaces for the endpoint (specified by EndpointId) are correctly configured and able to pass inbound or outbound DNS queries between your network and Resolver.
InboundQueryVolume	For inbound endpoints, the number of DNS queries forwarded from your network to your VPCs through the endpoint specified by EndpointId.
OutboundQueryVolume	For outbound endpoints, the number of DNS queries forwarded from your VPCs to your network through the endpoint specified by EndpointId.
OutboundQueryAggregateVolume	For outbound endpoints, the total number of DNS queries forwarded from Amazon VPCs to your network.
