# PutBucketMetricsConfiguration
Sets a metrics configuration (specified by the metrics configuration ID) for the bucket. You can have up to 1,000 metrics configurations per bucket. If you're updating an existing metrics configuration, note that this is a full replacement of the existing metrics configuration. If you don't include the elements you want to keep, they are erased.
**Note**
**Directory buckets ** - For directory buckets, you must make requests for this API operation to the Regional endpoint. These endpoints support path-style requests in the format `https://s3express-control.region-code.amazonaws.com/bucket-name `. Virtual-hosted-style requests aren't supported. For more information about endpoints in Availability Zones, see [Regional and Zonal endpoints for directory buckets in Availability Zones](https://docs.aws.amazon.com/AmazonS3/latest/userguide/endpoint-directory-buckets-AZ.html) in the *Amazon S3 User Guide*. For more information about endpoints in Local Zones, see [Concepts for directory buckets in Local Zones](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-lzs-for-directory-buckets.html) in the *Amazon S3 User Guide*.
Permissions
To use this operation, you must have permissions to perform the `s3:PutMetricsConfiguration` action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see [Permissions Related to Bucket Subresource Operations](https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-with-s3-actions.html#using-with-s3-actions-related-to-bucket-subresources) and [Managing Access Permissions to Your Amazon S3 Resources](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-access-control.html).
+ **General purpose bucket permissions** - The `s3:PutMetricsConfiguration` permission is required in a policy. For more information about general purpose buckets permissions, see [Using Bucket Policies and User Policies](https://docs.aws.amazon.com/AmazonS3/latest/dev/using-iam-policies.html) in the *Amazon S3 User Guide*.
+ **Directory bucket permissions** - To grant access to this API operation, you must have the `s3express:PutMetricsConfiguration` permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn't supported. This operation can only be performed by the AWS account that owns the resource. For more information about directory bucket policies and permissions, see [AWS Identity and Access Management (IAM) for S3 Express One Zone](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-express-security-iam.html) in the *Amazon S3 User Guide*.
HTTP Host header syntax
**Directory buckets ** - The HTTP Host header syntax is `s3express-control.region-code.amazonaws.com`.

## URI Request Parameters
The request uses the following URI parameters.
** [Bucket](#API_PutBucketMetricsConfiguration_RequestSyntax) **
The name of the bucket for which the metrics configuration is set.
**Directory buckets ** - When you use this operation with a directory bucket, you must use path-style requests in the format `https://s3express-control.region-code.amazonaws.com/bucket-name `. Virtual-hosted-style requests aren't supported. Directory bucket names must be unique in the chosen Zone (Availability Zone or Local Zone). Bucket names must also follow the format ` bucket-base-name--zone-id--x-s3` (for example, ` DOC-EXAMPLE-BUCKET--usw2-az1--x-s3`). For information about bucket naming restrictions, see [Directory bucket naming rules](https://docs.aws.amazon.com/AmazonS3/latest/userguide/directory-bucket-naming-rules.html) in the *Amazon S3 User Guide*
Required: Yes
** [id](#API_PutBucketMetricsConfiguration_RequestSyntax) **
The ID used to identify the metrics configuration. The ID has a 64 character limit and can only contain letters, numbers, periods, dashes, and underscores.
Required: Yes
** [x-amz-expected-bucket-owner](#API_PutBucketMetricsConfiguration_RequestSyntax) **
The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code `403 Forbidden` (access denied).
For directory buckets, this header is not supported in this API operation. If you specify this header, the request fails with the HTTP status code `501 Not Implemented`.
## Request Body
The request accepts the following data in XML format.
** [MetricsConfiguration](#API_PutBucketMetricsConfiguration_RequestSyntax) **
Root level tag for the MetricsConfiguration parameters.
Required: Yes
** [Filter](#API_PutBucketMetricsConfiguration_RequestSyntax) **
Specifies a metrics configuration filter. The metrics configuration will only include objects that meet the filter's criteria. A filter must be a prefix, an object tag, an access point ARN, or a conjunction (MetricsAndOperator).
Metrics configurations for directory buckets do not support tag filters.
Type: [MetricsFilter](API_MetricsFilter.md) data type
Required: No
** [Id](#API_PutBucketMetricsConfiguration_RequestSyntax) **
The ID used to identify the metrics configuration. The ID has a 64 character limit and can only contain letters, numbers, periods, dashes, and underscores.
