AWS Route53
Introduction
Amazon Route 53 is a scalable and highly available Domain Name System (DNS) web service designed to route end-user requests to internet applications. With Amazon Route 53, developers can effortlessly register domain names, manage DNS settings, and perform health checks to ensure reliable application performance. The service integrates seamlessly with other AWS offerings, providing a unified experience for traffic management and routing at any scale. Whether used for simple websites or complex, global applications, Amazon Route 53 delivers low-latency, high-availability DNS solutions to meet diverse needs.
Getting Started
Compatibility
vuSmartMaps support monitoring of your Cloud DNS that uses AWS Route53, the metrics are fetched using AWS Cloudwatch API interface.
Data Collection Method
vuSmartmaps collects health and performance data for given DNS service using Telegraf Agent. This agent collects data based on the source's configuration which carry the region of Route53 deployment and AWS Credentials with the required AWS IAM permissions.
Prerequisites
Dependent Configuration
To configure this O11ySource, create a 'credential' of type 'aws' under the 'Definition' tab.
Inputs for Configuring Data Source
- Data Source Name: Data source name to uniquely identify the source.
- AWS Credential: AWS credential that provides Access key and Secret key to access Cloudwatch.
- Polling Frequency: Specifies the interval in minutes at which data is collected. Data collection occurs once every specified period.
Firewall Requirement
To collect data from this O11ySource, ensure the following ports are opened:
| Source IP | Destination IP | Destination Port | Protocol | Direction |
|---|---|---|---|---|
| IP address(es) of the vuSmartmaps Server | AWS CloudWatch Endpoint | 443 | TCP | Outbound |
*Before providing the firewall requirements, please update the port based on the customer environment.
Configuring the Target
Health and Performance metrics of Route53 DNS is collected through AWS CloudWatch service. So AWS CloudWatch services must be enabled in your AWS account. AWS Route53 should have APIs configured for which monitoring is enabled. Please enabled detailed metrics if you want to see resource and method level metrics for HTTP APIs.
An IAM role or user with the following permissions to access CloudWatch metrics.
- cloudwatch:GetMetricData
- cloudwatch:ListMetrics
- cloudwatch:GetMetricStatistics
- sts:GetCallerIdentity
- tag:GetResources
- tag:GetTagKeys
- ec2:DescribeAvailabilityZones
Configuration Steps
- Enable the O11ySource.
- Select the Sources tab and press the + button to add a new Apache host to be monitored.
- Populate all the configurations.
- Click on Save to create the instance.
