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 Route 53 receives for a specified public hosted zone, such as the following:
-
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
orServFail
- 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 Route 53 console, Route 53 performs these operations automatically.
-
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 Amazon Web Services 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 Amazon resources, such as 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.
-
-
Create a CloudWatch Logs resource policy, and give it the permissions that Route 53 needs to create log streams and to send query logs to log streams. You must create the CloudWatch Logs resource policy in the us-east-1 region. 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/*
To avoid the confused deputy problem, a security issue where an entity without a permission for an action can coerce a more-privileged entity to perform it, you can optionally limit the permissions that a service has to a resource in a resource-based policy by supplying the following values:
-
For
aws:SourceArn
, supply the hosted zone ARN used in creating the query logging configuration. For example,aws:SourceArn: arn:aws:route53:::hostedzone/hosted zone ID
. -
For
aws:SourceAccount
, supply the account ID for the account that creates the query logging configuration. For example,aws:SourceAccount:111111111111
.
For more information, see The confused deputy problem in the Amazon IAM User Guide.
Note
You can't use the CloudWatch console to create or edit a resource policy. You must use the CloudWatch API, one of the Amazon SDKs, or the Amazon CLI.

- Log Streams and Edge Locations
-
When 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 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 Route 53 Global Network" on the Route 53 Product Details
page. -
- Queries That Are Logged
-
Query logs contain only the queries that DNS resolvers forward to 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 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.

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