Amazon Route 53
API Reference

CreateQueryLoggingConfig

Creates a configuration for DNS query logging. After you create a query logging configuration, Amazon Route 53 begins to publish log data to an Amazon CloudWatch Logs log group.

DNS query logs contain information about the queries that Amazon Route 53 receives for a specified public hosted zone, such as the following:

  • Amazon Route 53 edge location that responded to the DNS query

  • Domain or subdomain that was requested

  • DNS record type, such as A or AAAA

  • DNS response code, such as NoError or ServFail

Log Group and Resource Policy

Before you create a query logging configuration, perform the following operations.

Note

If you create a query logging configuration using the Amazon Route 53 console, Amazon Route 53 performs these operations automatically.

  1. Create a CloudWatch Logs log group, and make note of the ARN, which you specify when you create a query logging configuration. Note the following:

    • You must create the log group in the us-east-1 region.

    • You must use the same AWS account to create the log group and the hosted zone that you want to configure query logging for.

    • When you create log groups for query logging, we recommend that you use a consistent prefix, for example:

      /aws/route53/hosted zone name

      In the next step, you'll create a resource policy, which controls access to one or more log groups and the associated AWS resources, such as Amazon Route 53 hosted zones. There's a limit on the number of resource policies that you can create, so we recommend that you use a consistent prefix so you can use the same resource policy for all the log groups that you create for query logging.

  2. Create a CloudWatch Logs resource policy, and give it the permissions that Amazon Route 53 needs to create log streams and to send query logs to log streams. For the value of Resource, specify the ARN for the log group that you created in the previous step. To use the same resource policy for all the CloudWatch Logs log groups that you created for query logging configurations, replace the hosted zone name with *, for example:

    arn:aws:logs:us-east-1:123412341234:log-group:/aws/route53/*

    Note

    You can't use the CloudWatch console to create or edit a resource policy. You must use the CloudWatch API, one of the AWS SDKs, or the AWS CLI.

Log Streams and Edge Locations

When Amazon Route 53 finishes creating the configuration for DNS query logging, it does the following:

  • Creates a log stream for an edge location the first time that the edge location responds to DNS queries for the specified hosted zone. That log stream is used to log all queries that Amazon Route 53 responds to for that edge location.

  • Begins to send query logs to the applicable log stream.

The name of each log stream is in the following format:

hosted zone ID/edge location code

The edge location code is a three-letter code and an arbitrarily assigned number, for example, DFW3. The three-letter code typically corresponds with the International Air Transport Association airport code for an airport near the edge location. (These abbreviations might change in the future.) For a list of edge locations, see "The Amazon Route 53 Global Network" on the Amazon Route 53 Product Details page.

Queries That Are Logged

Query logs contain only the queries that DNS resolvers forward to Amazon Route 53. If a DNS resolver has already cached the response to a query (such as the IP address for a load balancer for example.com), the resolver will continue to return the cached response. It doesn't forward another query to Amazon Route 53 until the TTL for the corresponding resource record set expires. Depending on how many DNS queries are submitted for a resource record set, and depending on the TTL for that resource record set, query logs might contain information about only one query out of every several thousand queries that are submitted to DNS. For more information about how DNS works, see Routing Internet Traffic to Your Website or Web Application in the Amazon Route 53 Developer Guide.

Log File Format

For a list of the values in each query log and the format of each value, see Logging DNS Queries in the Amazon Route 53 Developer Guide.

Pricing

For information about charges for query logs, see Amazon CloudWatch Pricing.

How to Stop Logging

If you want Amazon Route 53 to stop sending query logs to CloudWatch Logs, delete the query logging configuration. For more information, see DeleteQueryLoggingConfig.

Request Syntax

POST /2013-04-01/queryloggingconfig HTTP/1.1
<?xml version="1.0" encoding="UTF-8"?>
<CreateQueryLoggingConfigRequest xmlns="https://route53.amazonaws.com/doc/2013-04-01/">

</CreateQueryLoggingConfigRequest>

URI Request Parameters

The request does not use any URI parameters.

Request Body

The request accepts the following data in XML format.

CreateQueryLoggingConfigRequest

Root level tag for the CreateQueryLoggingConfigRequest parameters.

Required: Yes

CloudWatchLogsLogGroupArn

The Amazon Resource Name (ARN) for the log group that you want to Amazon Route 53 to send query logs to. This is the format of the ARN:

arn:aws:logs:region:account-id:log-group:log_group_name

To get the ARN for a log group, you can use the CloudWatch console, the DescribeLogGroups API action, the describe-log-groups command, or the applicable command in one of the AWS SDKs.

Type: String

Required: Yes

HostedZoneId

The ID of the hosted zone that you want to log queries for. You can log queries only for public hosted zones.

Type: String

Length Constraints: Maximum length of 32.

Required: Yes

Response Syntax

HTTP/1.1 201
Location: Location
<?xml version="1.0" encoding="UTF-8"?>
<CreateQueryLoggingConfigResponse>
   <QueryLoggingConfig>
      <CloudWatchLogsLogGroupArn>string</CloudWatchLogsLogGroupArn>
      <HostedZoneId>string</HostedZoneId>
      <Id>string</Id>
   </QueryLoggingConfig>
</CreateQueryLoggingConfigResponse>

Response Elements

If the action is successful, the service sends back an HTTP 201 response.

The response returns the following HTTP headers.

Location

The unique URL representing the new query logging configuration.

Length Constraints: Maximum length of 1024.

The following data is returned in XML format by the service.

CreateQueryLoggingConfigResponse

Root level tag for the CreateQueryLoggingConfigResponse parameters.

Required: Yes

QueryLoggingConfig

A complex type that contains the ID for a query logging configuration, the ID of the hosted zone that you want to log queries for, and the ARN for the log group that you want Amazon Route 53 to send query logs to.

Type: QueryLoggingConfig object

Errors

For information about the errors that are common to all actions, see Common Errors.

ConcurrentModification

Another user submitted a request to create, update, or delete the object at the same time that you did. Retry the request.

HTTP Status Code: 400

InsufficientCloudWatchLogsResourcePolicy

Amazon Route 53 doesn't have the permissions required to create log streams and send query logs to log streams. Possible causes include the following:

  • There is no resource policy that specifies the log group ARN in the value for Resource.

  • The resource policy that includes the log group ARN in the value for Resource doesn't have the necessary permissions.

  • The resource policy hasn't finished propagating yet.

HTTP Status Code: 400

InvalidInput

The input is not valid.

HTTP Status Code: 400

NoSuchCloudWatchLogsLogGroup

There is no CloudWatch Logs log group with the specified ARN.

HTTP Status Code: 404

NoSuchHostedZone

No hosted zone exists with the ID that you specified.

HTTP Status Code: 404

QueryLoggingConfigAlreadyExists

You can create only one query logging configuration for a hosted zone, and a query logging configuration already exists for this hosted zone.

HTTP Status Code: 409

Examples

Example Request

The following request creates a configuration for the hosted zone Z1D633PJN98FT9. DNS query logs are sent to the log group with the ARN arn:aws:logs:us-east-1:111111111111:log-group:example.com:*.
