Amazon Route 53 Resolver is a scalable and fully managed DNS service from AWS that provides DNS resolution for resources within your VPCs and across hybrid cloud environments. It supports both inbound and outbound DNS queries, as well as DNS Firewall for enhanced protection. Monitoring Route 53 Resolver is essential to ensure reliable DNS performance, maintain compliance, and strengthen security against unauthorized or malicious DNS activity.
To learn how to create a new AWS Route 53 Resolver monitor, refer here.
Go to the Monitors Category View by clicking the Monitors tab. Click on the Route 53 Resolver instance available under Amazon in the Cloud Apps section. Displayed is the Amazon Route 53 Resolver bulk configuration view distributed into the following tabs:
By clicking a monitor from the list, you'll be taken to the AWS Route 53 Resolver dashboard which includes the following tabs:
| Parameter | Description |
|---|---|
| RESOLVER ENDPOINT INFORMATION | |
| Overall Resolver Endpoint Status | A code that specifies the current status of the Resolver endpoint. Possible values: CREATING | OPERATIONAL | UPDATING | AUTO_RECOVERING | ACTION_NEEDED | DELETING. |
| Endpoint Direction | Indicates whether the Resolver endpoint allows inbound or outbound DNS queries. Possible values: INBOUND, OUTBOUND, INBOUND_DELEGATION. |
| IP Address Count | The number of IP addresses that the Resolver endpoint can use for DNS queries. |
| Resolver Endpoint Capacity Status | The capacity status of the Resolver endpoint indicating the ENI utilization levels at the time of polling. Possible values: OK, Warning, Critical. |
| HEALTH OF ELASTIC NETWORK INTERFACES | |
| Healthy Elastic Network Interfaces | The average number of elastic network interfaces in the OPERATIONAL status at the time of polling. This means that the Amazon VPC network interfaces for the endpoint are correctly configured and able to pass inbound and outbound DNS queries between your network and resolver. |
| Unhealthy Elastic Network Interfaces | The average number of elastic network interfaces in the AUTO_RECOVERING status at the time of polling. This means that the resolver is trying to recover one or more of the Amazon VPC network interfaces that are associated with the endpoint. |
| PERCENTAGE OF UNHEALTHY ENIs | |
| Percentage of Unhealthy ENIs | The average percentage of ENIs in the AUTO_RECOVERING status at the time of polling. |
| INBOUND QUERIES RATE | |
| Inbound Queries Rate | For inbound endpoints, the number of DNS queries forwarded from your network per minute to your VPCs through the specified endpoint between the poll interval (in Queries/min). |
| Inbound Queries | For inbound endpoints, the number of DNS queries forwarded from your network to your VPCs through the specified endpoint between the poll interval. |
| OUTBOUND QUERIES RATE | |
| Outbound Queries Rate | For outbound endpoints, the number of DNS queries forwarded from your VPCs per minute to your network through the specified endpoint between the poll interval (in Queries/min). |
| Outbound Queries | For outbound endpoints, the number of DNS queries forwarded from your VPCs to your network through the specified endpoint between the poll interval. |
| AGGREGATE OUTBOUND QUERIES RATE | |
| Aggregate Outbound Queries Rate | For outbound endpoints, the total number of DNS queries forwarded from Amazon VPCs per minute to your network, including queries from shared Resolver rules between the poll interval (in Queries/min). |
| Aggregate Outbound Queries | For outbound endpoints, the total number of DNS queries forwarded from Amazon VPCs to your network, including queries from shared Resolver rules between the poll interval. |
| IP Addresses | |
| IP Address | The IP address associated with the Resolver endpoint. |
| IP Address ID | The ID of the IP address associated with the Resolver endpoint. |
| Status | A status code that gives the current status of the IP address. Possible values: CREATING | FAILED_CREATION | ATTACHING | ATTACHED | REMAP_DETACHING | REMAP_ATTACHING | DETACHING | FAILED_RESOURCE_GONE | DELETING | DELETE_FAILED_FAS_EXPIRED | UPDATING | UPDATE_FAILED | ISOLATED |
| Subnet ID | The ID of the subnet associated with the IP address. |
| Aggregate Inbound Queries | For each IP address associated with an inbound endpoint, the number of DNS queries forwarded from your network to the specified IP address between the poll interval. |
| Aggregate Outbound Queries | For each IP address associated with an outbound endpoint, the total number of DNS queries forwarded from Amazon VPCs to your network, including queries from shared Resolver rules, between the poll interval. |
| Parameter | Description |
|---|---|
| Endpoint ID | The ID of the Resolver endpoint. |
| Host VPC ID | The ID of the VPC in which the Resolver endpoint is created. |
| Resolver Endpoint Type | The Resolver endpoint IP address type. Possible values: IPV6, IPV4, DUALSTACK. |
| Creation Time | The date and time that the endpoint was created. |
| Modification Time | The date and time that the endpoint was last modified. |
